What Temps Are Best For Bread Yeast In Moonshine?

Moonshine Rum and Bourbon Recipes SPIRITS RECIPES Distilling spirits is as much the art of preparing the fermented wash to distill as it is the actual distilling. These recipes were prepared so that the beginning distiller can have early success in producing quality spirits.

These recipes are for 5 gallons of fermented wash and the ingredients can be adjusted proportionally for greater or lesser quantities. You will need a stock pot and a fermentation vessel large enough for the batch you wish to produce. Equipment used for home brewing beer is typical. Rum Rum is usually the spirit first recommended to the new distiller.

It is the easiest to produce with ingredients locally available to everyone. Rum is the distilled fermentation of molasses. Molasses is the by product of refining sugar cane into white granulated sugar. Molasses still contains sugar ranging from 40% sugar content in blackstrap molasses to as high as 55% in light table molasses.

While it can be argued that the best rum comes from a fermentation of pure table molasses and water, the quantity of molasses required for such becomes very expensive for the hobby distiller. Brown sugar is white sugar with a coating of molasses (use only “Cane” sugar, if the package doesn’t say “Cane Sugar” then it is beet sugar).

Brown sugar (use the dark variety) can produce very tasty rum at far less expense than using pure molasses. Be aware that we are using two pounds of brown sugar per gallon. If you have access to reasonable cost unsulphered table molasses the recipe could be altered to substitute two 12 oz jars of molasses per pound of the sugar.

• Ingredients:
• 10 lbs of pure cane dark brown sugar
• 4 gallons (approximate) of prepared water (see other distilling information)
• 1 sacket of Rum Yeast (for substitution see other distilling information)
• Procedure:

Heat 2 to 3 gallons of the water to boiling in a large stock pot then reduce heat. Dissolve the brown sugar and/or molasses in the water. Hold temp above 165F for 10 minutes to kill bacteria. Pour the sugar water into your fermentation vessel. Top off with cool water to a total volume of 5 gallons.

Let cool to 80 F. Sprinkle yeast across surface, allow to stand for 15 – 20 minutes and then gently stir in. Ferment for 5 to 7 days (as long as fermentation continues). Siphon into your still boiler keeping as much of the yeast sediment from entering the still as possible. Distill per still instructions.

Age for 30 days at distilled strength shaking once a day. Dilute with aerated distilled water to 80 proof. Enjoy!

1. Easy Bourbon Recipe
2. Ingredients:
3. 4 lbs corn meal (grocery store grade)
4. 3.3 lb can of unhopped malt extract syrup (from any homebrew shop)
5. 8 lbs of pure cane sugar (if it doesn’t say “cane” then it is beet sugar)
6. 1 packet (4g) of alpha amylase enzyme
7. 1 sacket Whisky Yeast w/AG (the amyloglucosidase is important for max yield)
8. 12 toasted oak chips (for aging)
9. Procedure Overview:

Heat 2 to 3 gallons (3 will be easier to stir than 2) of the water to approximately 200 F (just shy of boiling) then reduce heat. Slowly pour in the corn meal while stirring. Continue to cook and stir until corn is fully gelatinized (10-15 minutes). Dissolve the sugar and the malt syrup in the corn meal/water porridge. Turn off heat and allow to cool to 165F. Stir in the alpha amylase enzyme. Allow to rest for 1 hour. Pour the mash into your fermentation vessel. Top off with cold (chlorine free) aerated water to just over 5 gallons (approx. a quart over). Let cool to <85 F. Sprinkle room temperature whiskey yeast across top of mash. Wait 15-20 minutes until yeast has rehydrated then stir in gently. Cover and ferment at 75-80F until fermentation is completed (4-7 days). Strain mash into the still boiler using a large straining bag or clean white pillow case. Distill per instructions provided with the still. Age at distilled strength with the oak chips for 30 days or longer shaking once daily. Strain off oak chips and dilute with aerated distilled water to 80 proof. Enjoy! OTHER INFORMATION FOR PREPARING A WASH Water: The quality of your water is important to making good spirits. The water should be clean, chlorine free (chlorine can kill yeast), ideally have some calcium content (but devoid of iron content) and be approximately 5.5 to 6 on a PH scale (just slightly acid). PH can be measured and adjusted with supplies purchased from a homebrew shop. If you want to proceed without actually measuring the PH most municipal water supplies and bottled store water have a neutral PH of 7 to 8. Add ¼ tsp of lemon juice per gallon and then your water will likely be in the ballpark. Calcium content can be increased by adding 1/8 tsp of gypsum per gallon. Aeration can be accomplished by filling a sealable container half full with your water and shaking it vigorously for 60 seconds. Aeration can also be done with an aquarium air pump used with new clean tubing and a new clean bubbler stone. Pump bubbles through your wash or mash for 20 minutes. Yeast: Different yeasts can be used successfully. Bread yeast does work but it will die at a lower alcohol percentage than distilling yeast strains and settles out poorly. Inconsistent results using bread yeast are due to the fact that all brands and types within each brand are different and bread yeast manufacturers never reveal which yeast strain they are using. Bread yeast will require added nutrients to complete a proper fermentation. Turbo yeasts already include the nutrients (no additional nutrients required) that are required for fermentation and can be used with most any type of spirit. Specific turbo yeasts designed with the right nutrients for the application (whiskey, vodka, rum, etc.) are perhaps the easiest and most foolproof to use. Generic distillers yeast (DADY) works well in grain mashes and in particular for the production of ethanol fuel. It requires added nutrients in sugar type mashes. Wine yeast is often obtainable rather economically (try Lalvin EC-118) and will also require added nutrients in sugar washes. Wine yeasts are sold in small sackets so you will need one for every 2 gallons of wash. Homebrew beer yeasts can be used for grain mashes but they are typically not used very often for distilling purposes as they are generally limited to lower alcohol fermentations and typically develop flavor profiles which do not suit many types of spirits. For yeast nutrients you will need something that includes both vitamins/minerals and DAP (diammonium phosphate) or buy the two separately. If nothing else is available to you can add a small can of tomato paste and throw a few raisins into your wash to add nutrients. Grain mashes typically require less added nutrients as the grain supplies them. Fermentation Temperature: Yeast works in a very narrow temperature range, Most all yeasts will die at high temperatures (above 85 F) and work very slowly (if at all) at low temperatures (below 65 F). Keep your ferment around normal room temperature (72 to 78 F) for optimum results. Be aware that the fermentation process itself generates some heat particularly with large batches. It may be necessary to keep your fermentation vessel in a cooler place than your desired temperature especially for the first few days. Fermentation Time: Complete fermentation can take from 3 days to two weeks depending on the ingredients, the yeast being used, and the temperature of the fermentation. Rigorous fermentation will be obvious during the 2 nd and 3 rd days after tossing your yeast but will become much more subtle after that. The best way to tell when fermentation has ceased is to use a fermentation vessel with an air lock. That way you will see when the air lock stops bubbling entirely. Generally speaking it is OK to leave a wash sealed in the fermentation vessel for a few days if needed before you distill. : Moonshine Rum and Bourbon Recipes

What temp should yeast be for moonshine?

Video Transcription – Howdy folks, and welcome back for another Heads episode. In this episode we are going to be discussing the turbo yeast mash. While there is a lot of bad rep around turbo yeast, we definitely recommend starting this way for new distillers.

• It’s so easy, and it’s super cheap, so you can really get the process under your belt with a couple batches without really breaking the bank, and to be honest I still use turbo yeast mashes, especially when I am doing something like using one of my essences.
• Turbo yeast mashes are really pretty simple.

You just mix sugar with water, add the yeast, let it ferment, and you should be good to go with the distilling process. There’s a couple optional extras that we can add in that we will discuss later on in this video. But, to begin with, we’ve just got three gallons of warm water and 18 pounds of sugar.

1. We add the sugar to the water and stir it all in.
2. Again, we used warm water just to help the sugar dissolve and we will be adding the other two gallons of water later on.
3. So, now that we’ve got the sugar mostly dissolved, we are going to add back in our cool water to help cool back down the mash.
4. Generally, you want to add until there is about 5 or 6 gallons of total liquid.

With all the sugar dissolved and the cool water added, it is just about lukewarm temperature which should be fine to add your yeast. Cut open the yeast packet, and pour the entire thing in. give it a quick stir to mix the yeast in, put the lid on, and you should be ready for fermentation.

With our 48-hour turbo yeast, it will generally take about 48 hours to reach 14% alcohol by volume, and 5 days total to reach about 20% alcohol by volume. Generally, you want to ferment it at a little bit warmer temperatures than you would a typical, beer yeast or wine yeast, at 70-85 degrees Fahrenheit.

Optimal temperature would be about 77 degrees Fahrenheit. At temperatures higher than 77 degrees Fahrenheit, the yeast are going to produce more byproducts, giving your final distillate a slightly funkier flavor. So, as you can see, turbo yeast mashes are very easy and simple to do.

• They are also very cheap since a 25 pound bag of sugar at Costco costs about $10, and the bag of yeast costs about $4.
• As a beginning distiller, this is a very cost effective way for you to get your feet under you and learn about distilling without breaking the bank.
• Hopefully you found this informative and good luck to you.

And as always, thanks for tuning in!.

What temperature do you distill with bakers yeast?

Types of Yeast – There are many different types of yeast. Most types are varieties of a species of yeast called Saccharomyces Cerevisiae, and while they have a lot in common, they can behave very differently from one another. It can seem a little counterintuitive for one species to be so diverse, but a good analogy is to think about the different varieties of apples and how different they can be.

1. All yeasts need similar nutrients, but some can tolerate more heat, some can convert the sugar into alcohol more quickly, and some can handle higher ABV.
2. A major consideration is the amount of nutrients that you pitch in with the yeast and how that can affect the flavor in the ferment.
3. Ideally, all the nutrients will be consumed by the yeast, but there are times when that doesn’t happen or the fermentation process gets stuck and you get an incomplete conversion of sugar to ethanol.

This can be catastrophic for beer production, but when you’re making spirits, you have additional processing steps that may or may not remove some of the off-putting flavors. Yeast needs to be in its “Goldilocks zone”, where it’s not too hot or too cold for the yeast to do its thing.

Too cold and the yeast goes dormant. Too hot, and they’ll be killed off. Most yeast thrives at temperatures above 65°F and below 80°F, but each variety has a different sweet spot. There are some strains of yeast that can survive outside this temperature range, but this is where most varieties are happy.

Even if a yeast can technically survive in a temperature range, it doesn’t mean that it’s happy there or that it will provide you with the best flavors. Always make sure to check your supplier’s recommendations on optimal temperatures for the yeast varieties you’re using.

What temperature do you pitch bread yeast in mash?

100°–110°F is the ideal temperature for Active Dry Yeast.120°–130°F is the ideal temperature for RapidRise ® and Bread Machine Yeast.

What is the alcohol tolerance of bread yeast?

Can I use bakers yeast to produce wine? Over the centuries, many new yeast species and strains have been discovered, bred and then chosen to perform specific tasks such as rising bread, producing alcohol, biofuels and probiotics. This is due to each strain having unique characteristics causing them to perform better in certain situations compared to others.

• Baker’s yeast is the common name for yeast strains used in bread and other bakery products, serving as a leavening agent which causes the bread to rise (expand and become lighter).
• Fermentable sugars within the bread are converted into CO2 and ethanol which causes the rising effect.
• Although bakers and wine yeast are mostly from the same genus and specie, Saccharomyces Cerevisiae, they are all different strains.

Different strains will have different fermentation capabilities, including by-product production, certain tolerances towards alcohol concentrations and osmotic stress and the type of raw material used for fermentation. Tolerance towards alcohol: Wine yeast has a high alcohol tolerance for it can survive conditions up to 15 -16 % v/v.

1. Bread yeast, on the other hand, can probably produce alcohol up to 6-8 % v/v.
2. This means that bread yeast cannot survive the high alcohol content desired by winemakers.
3. If you are producing beer, cider or any low alcoholic strength drinks at home, bread yeast will be more than capable.
4. Osmotolerance: Baker’s yeast are normally not known to have a high osmotic tolerance (not able to withstand high sugar concentrations).

Excess sugar, as well as other dissolved solids in a fermentation medium, will pull water out of the yeast cells, desiccating and killing them. This will result in stuck and incomplete fermentation. Grapes are known for having a natural high concentration of sugar at full ripeness and this might be above what bread yeast can tolerate.

• By product production: During fermentation, many other products are produced, but in much smaller quantities.
• These products usually contribute to the aroma and flavour of your fermented product.
• In the wine industry, the aromatic profile of the wine is extremely important and thus, yeast selection is done thoughtfully.

Bread yeast is not known to be uniquely aromatic compared to wine yeast strains and would thus not be able to satisfy the required aroma complexity for wine production. Raw material: Bread yeast is used to ferment grains whereas wine yeast is used to ferment fruits.

1. The composition of fruits and grains differs, which includes the type of sugars and nutrients naturally present.
2. Clarity of fermented product: As fermentation slows down, you will notice wine yeast clumping together and settling at the bottom of the fermenter causing the wine to become clear – a process called flocculation.

Baker’s yeast, on the other hand, does not clump and flocculate as readily as wine yeast. Instead, it slowly settles to the bottom as a fine haze that will not be able to be cleared out completely. Settling can take days or even weeks. Wine made from baker’s yeast will thus remain hazy for long periods, making it unattractive for consumers while imparting a yeasty taste.

What temperature is too hot for yeast to ferment?

What Temperature Kills Yeast – Bob’s Red Mill Blog

What Temperature Kills Yeast

Select a Category Recipes Healthy Living Special Diets , on February 21 2018 by Bob’s Red Mill Making bread is an art. Or perhaps a science. In any case, with breadmaking, there are two kinds of leaveners typically used in the baking process. One is baking soda or powder, and the other is yeast. Yeast is a live fungal organism made of a single cell.

• Yeast has over 160 different species that live in us and all around us.
• The type of yeast that is used when making bread is usually the kind that comes in little paper packets.
• It looks like beige colored granules that essentially lie dormant until they come into contact with warm water at just the right temperatures.

When the warm water hits the yeast, it reactivates it and “wakes it up.” Then it begins to eat and multiply. The yeast organism feeds on the simple sugars found in flour. As they feed, they release chemicals and gases like carbon dioxide and ethanol, along with energy and flavor molecules.

This is part of the process used to give bread its rise, and it is sometimes referred to as the fermentation process. As the carbon dioxide gas expands, the bread dough rises. This process of rising happens a lot slower though with yeast than it does with baking powder or baking soda used as the leavening agent.

Yeast is also what imbues the bread with all of its yummy flavors and smells. Some professional bakers believe that carbon dioxide is the sole rising agent, while ethanol is the sole flavoring agent, but it’s not entirely so black and white. Ethanol is formed in equal parts to the carbon dioxide, so ethanol also contributes to the fermentation process every bit as much as carbon dioxide does. Not only does the yeast help produce carbon dioxide and ethanol, it also assists in the development of gluten. Gluten is the substance that traps gas bubbles and gives the dough its structure. With no-knead recipes, this process is even more important, because as these gas bubbles move around inside the dough, it helps to push and rearrange the proteins into the necessary structure without any kneading required.

1. The short story is that without yeast, your bread won’t rise properly, and you won’t get the same look or flavor that you would when yeast is used.
2. How do you prepare the yeast to be mixed into your next batch of dough? This process is sometimes referred to as proofing the yeast.
3. It is when you add yeast to water, then feed it sugar and stir it together.

As the yeast sits in the water, it begins to dissolve and the yeast is activated. Once the yeast has been activated or “awakened,” it will begin to feed on the sugar in the water. The next step when proofing yeast is to let the yeast mixture sit for several minutes.

• A good benchmark is to allow 2 to 3 minutes for it to completely dissolve, and then an additional 2 or 3 minutes for the yeast to start growing and show signs of life.
• Signs of lively yeast include little surface bubbles on the top of the water.
• Depending on the variety of yeast, sometimes the mixture may expand even more than you expect! If you do all of these steps and find that nothing is happening and you are sure you kept your water at an appropriate temperature, then it could be a sign that you need a new batch of yeast, as the batch you’re trying to use may be too old.

Yeast that is older and doesn’t respond to the proofing process is sometimes referred to as “tired” yeast. The reasoning behind the whole method of proofing your yeast is so that you can prove the yeast is viable and ready to do its job before you mix it into your bread dough.

• Once your yeast has been proved, the next step is to begin stirring in your flour and salt.
• Be careful that you stir in the flour first as a bit of a buffer, because yeast organisms don’t like salt.
• If you pour the salt in first, then your yeast organisms will not be happy campers! At what temperature can you see the best results when proofing your yeast? Good question.

Yeast is a finicky little single-celled organism. With dry yeast, if your water is too cold, the yeast will not activate. Or, if they do wake up, they might release a substance that hinders the formation of gluten. Then again, if your water is too hot, you will kill the little buggers and they will be useless.

• Typically, hot water somewhere in the range of 105° and 115°F is ideal for proofing dry yeast.95°F is often recommended for live yeast, but it may not be hot enough at 95°F for activating the dry yeast.
• At this temperature, once you pour it into the bowl and dissolve the sugar, it will cool a little bit and be the perfect temperature range for dissolving and activating your bread risers.

Not sure if your water is the right temp? One way to test this is to do the wrist test. Drizzle a few drops of your water onto the inside of your wrist. If it is warm and comfy for you, then it will no doubt be warm and comfy for your yeast too. However, if it is not warm and instead feels hot, it most likely will be too hot for your yeast to survive.

By the same token, if it is too cold, then your yeast will simply remain dormant. If you’re using fresh yeast, then you can shoot for temperatures that range between 95° and 100°F for the proofing process. This is because fresh yeast (sometimes called cake yeast), doesn’t need to be dissolved in the water.

It simply needs to be combined with water, and when it is combined, it will start feeding and growing right away. Regardless of the type of yeast you use, if your water reaches temperatures of 120°F or more, the yeast will begin to die off. Once water temps reach 140°F or higher, that is the point where the yeast will be completely killed off.

1. If you’re doing the wrist test, 120°F feels pretty hot, whereas 140°F feels extremely hot.
2. If you don’t trust the wrist test, you can always use a candy thermometer to test the temperatures and get a more accurate reading that way.
3. Is there ever a time you can use higher water temperatures? Yes, but only when you are using instant yeast.

Instant yeast, sometimes referred to as rapid rise yeast, doesn’t require proofing with warm water before using it. This type of yeast is mixed with flour first, instead of water right away, so the temperatures that are suggested are much higher and can range from 120° to 130°F.

• Eep in mind that even though this type of yeast doesn’t require proofing, you can proof it if you suspect it might not be lively.
• You would simply proof it the same way you would proof the active dry yeast.
• Also, since flour is usually around room temperature, this could be the reason higher temperatures are tolerated.

The guide below will give you a rough idea of ideal water temperatures for proving your yeast.

Water at -4°F means your yeast will be unable to ferment. Water at 68° to 104°F means that your yeast’s ability to grow will be hindered, and its growth rate will be reduced. Water at 68° to 81°F are probably the most favorable range for the yeast to grow and multiply in. Water at 79°F are considered the optimum temperature for achieving yeast multiplication. Water at 81° to 100°F is the optimum temperature range for the fermentation process. Water at 95°F is the fermentation temperature that yields the best result. Water at 140°F or higher is the kill zone for yeast. At temps like this or higher, you will have no viable live yeast left.

Of course, these tentative estimations can be higher or lower depending on the type of yeast you are using, and whether it is, live yeast, or rapid rise yeast. The bottom line is that yeast thrives in warm water, sleep in cold water, and die in hot water.

Can bread yeast be used to ferment alcohol?

Every so often we run across someone who is making wine with bread yeast. Yes, I’m talking about the plain ole’ yeast you pick up in the baking section of your local grocery store. And every time I hear of someone using bread yeast, the question that always screams in my head is, “why?” There are so many advantages to using wine yeast and so many disadvantages to using bread yeast that I can’t imagine why anyone would want to use it.

• The only conclusion I can come up with is that there is a strong misunderstanding about what yeast really are and what they do.
• Yeast is what turns sugar into alcohol.
• Yeast cells are living organisms that consume and digest the sugars.
• As a result, they excrete alcohol and CO2 gas.
• Along with these two compounds also comes various trace amounts of enzymes, oils, acid, etc.

These are the things that give different alcohols their different characters. The point is all yeast are not the same. How one strain responds to the sugars varies from the next. There are literally thousands of different strains that have been identified or developed as hybrids, all with varying characteristics that make them suitable or not-so-suitable for performing a particular task, whether it be fermenting wine or raising bread. Another reason making wine with bread yeast is not a good idea is that bread yeast do not clear out very readily or settle very firmly, either. They typically will form a low layer of hazy wine in the bottom of the fermenter that will never completely clear out.

• Even more importantly, bread yeast produce alcohol that is plagued with a lot of off-flavors.
• The bread yeast becomes so stressed and has to work so hard that off-flavored enzymes and fatty acids are produced along with the alcohol.
• There are several other issues with using bread yeast to make your wine, but these are the big ones: the alcohol, the clearing, and the flavor.

There are many, many different strains of wine yeast, These yeasts are bred over time to produce something of a ‘super’ wine yeast. Each one becoming the ultimate choice for tackling the particular type or style of wine. Some wine yeast ferment to total dryness better than others.

Some have better alcohol tolerance than others. Some put off fruitier aromas than others. Some pack more firmly to the bottom of the fermenter than others. Some wine yeast even have flavor qualities that make them ideal for fermenting one type of fruit over another. The list goes on and on. And it goes without say, they all do it better than bread yeast.

On our website, we have a wine yeast profile charts listed for each line of wine yeast we carry: Red Sta r, Lalvin and Vintner’s Harvest Wine Yeast. You can view these profile charts from a link on the product page for each of these wine yeasts. The last thing I’d like to point out is that buying actual wine yeast to make your wine is not expensive.

1. Currently, you can purchase wine yeast for as little as $2.00.
2. I haven’t priced bread yeast recently, but there can’t be that much difference in price.
3. So if you value your time and effort at all go with the wine yeast.
4. Don’t try making your wine with bread yeast.

What happens to yeast at 50 degrees?

At the higher temperature 45 to 50 degrees Celsius, enzymes begin to denature, so the reaction slows down. But the other end, between five and 30 degrees Celsius, there is simply less thermal energy, so the reaction is slower.

What is the optimal growth temperature for Baker’s yeast?

DISCUSSION – In this study, optimum pH value necessary for growth of S. cerevisiae Kalecik 1 and S. cerevisiae Narince 3 was found as 4.00, since maximum values for specific growth rate and dry mass were obtained at this pH. It can be seen from the results that, growth of the yeasts were adversely affected at lower and higher pH values.

There were considerable decreases in dry mass especially at high pH levels. It is reported that, most of the yeasts grow very well between pH 4.5-6.5, but nearly all species are able to grow in more acidic or alkaline media ( 17 ). Low or high pH values are known to cause chemical stress on yeast cell, which is demonstrated in our study.

It is determined that glycerol production by S. cerevisiae Kalecik 1 was positively affected by increasing pH. Maximum glycerol concentration and glycerol yield tended to increase with increasing pH, that the best results were obtained at pH 6.46. Specific glycerol production rate reached its maximum value at pH 5.92.

For the strain Narince 3, both maximum glycerol concentration and glycerol yield remained constant between pH range of 4.00- 5.98, but they considerably increased above pH 5.98. Maximum glycerol concentration was obtained at pH 6.48, while maximum specific glycerol production rate was obtained at pH 6.27.

The positive effect of high pH on glycerol production may be explained in relation with the activity of the enzyme aldehyde dehydrogenase. It is reported that, activity of the enzyme aldehyde dehydrogenase is increased at high pH values and acetic acid is produced ( 18 ).

• This oxidation generates a molecule of NADH, which requires reoxidation to maintain the redox balance of the cell.
• Then, glycerol is formed by the reduction of dihydroxyacetone phosphate to glycerol-3-phosphate, and then to glycerol.
• It is indicated in the studies concerning industrial glycerol production by S.

cerevisiae that, higher glycerol yields were obtained under alkaline conditions. Thus, alkali-steered process is one of the processes which is used commercially for substantial overproduction of glycerol ( 16, 18 ). Therefore, increase in glycerol production amount with increasing pH is an expected result in our study.

When it is thought that S. cerevisiae Kalecik 1 and S. cerevisiae Narince 3 are wine yeast strains, glycerol production amount of those strains at pH values of grape must (3.5-4.2) should be also taken in to account. It is reported that the most available pH range for alcohol fermentation in wine production is 3.8-4.2.

This pH range provides the conditions for S. cerevisiae to be dominant species of the fermentation, and also for inhibition of wild yeasts ( 18 ). In the present study, it was determined that in the range of pH values of grape must (3.5-4.2), maximum glycerol concentrations obtained in synthetic medium were 8.0 and 7.2 gL −1 for Kalecik 1 and Narince 3 strains, respectively.

1. Since the obtained glycerol levels are similar to those expected for wine, this might give the opinion that the strains could be selected as glycerol producing ones after further investigations.
2. In the experiments concerning the effects of temperature, optimum yeast growth was observed at 30°C for both of the strains.

Dry mass and specific growth rates were maximum at 30°C, and with increasing the temperature to 35°C, these values decreased. Temperature is accepted as one of the most important physical parameters influencing yeast growth. It is known that most laboratory and industrial yeasts generally grow best between 20-30°C ( 17 ).

It is reported that wine yeasts grow well between 25-33°C; temperatures between 25-30°C is more available for cell reproduction, and 30-37°C for alcohol production ( 1, 13 ). In the present study, it can be observed that maximum glycerol concentration was obtained at 30°C for both of the strains. Specific glycerol production rate did not change significantly between 25-30°C for the strain Kalecik 1, while maximum glycerol concentration increased.

There was not any important change in maximum glycerol concentration between the temperature range of 30-35°C for Kalecik 1 strain. Maximum concentrations of glycerol produced by S. cerevisiae Narince 3 was not significantly affected between 20-25°C, while specific glycerol production rate increased.

1. Maximum levels for glycerol concentration, glycerol yield, and specific glycerol production rate were obtained at 30°C for that strain.
2. It is reported the amount of glycerol formed during fermentation generally increases with increasing temperature, and the optimum temperature for glycerol production by yeasts is apperantly similar to the optimum growth temperature of the organism ( 15, 18 ).

The data obtained in the present study are supported by several studies which indicate that wine yeast strains of S. cerevisiae have an optimum temperature between 20°C and 32°C for glycerol production ( 5, 15, 18 ). In a study carried out with S. cerevisiae and other yeasts in natural grape juice, S.

1. Cerevisiae was found to dominate in the fermentation at 25°C and pH 3.0-3.5, that cell population reached to 10 7 -10 8 cell mL −1 in three days ( 6 ).
2. When the results obtained by the two strains are compared, it can be observed that there are similarities in the responses of the strains to different pH and temperature levels.

When it is thought that both of the strains are originated from grape, similar behaviour at various conditions could serve as an expected result. It was determined that glycerol concentrations obtained by the strain Kalecik 1 were slightly higher than those obtained by Narince 3, at almost all conditions used.

1. There are several studies indicating the effect of yeast strain on glycerol production ( 14, 15 ).
2. The individual growth and glycerol production behaviour of two different strains were also pointed out in the present study.
3. In conclusion, this study demonstrated growth and glycerol production characteristics of two indigenous wine yeasts at different pH and temperatures.

It is thought that the obtained data give idea about some of the important technological properties of the yeasts. It is known that, glycerol production could be controlled by the choice of optimized cultivation conditions and/or selection of appropriate strains.

The strains used in the study are originated from wine grapes grown in Turkey and have a potential use in wine production. Maximum glycerol concentrations were obtained between 6.5-9.1 gL −1, which were changed between 6.5-8.0 gL −1 at pH values similar to pH of grape must. In a study by Remize et al.

( 14 ), glycerol production of some commercialized wine yeasts were investigated. Maximum glycerol concentrations of the examined strains were reported as 6.4-8.9 gL −1 in a synthetic medium, which were similar to our results. The obtained glycerol concentrations demonstrate the potential of the yeasts for improving wine quality.

How long does bread yeast take to ferment alcohol?

Download Article Download Article Many people are attracted to the idea of making their own alcoholic beverages. Luckily, it is straightforward and inexpensive to make alcohol from table sugar (sucrose). You need a fermentation vessel, sugar, and yeast for the fermentation process, and the ability to purify the alcohol you’ve made. Once you’ve produced the alcohol, you can use it to make liquors or mixed drinks.

1. 1 Use materials safe for consumption. You should only use food grade plastic buckets or glass carboys as your fermentation vessel. Make sure that the lid is food grade as well. A 7.5 gallon (28 L) vessel will allow for 5.5 to 6 gallon (21 to 23 L) batches. Keep in mind that you may occasionally need to stir the batch, so containers such as buckets are often ideal.
2. 2 Leave extra room. You need about 1.5 to 2 gallons (5.7 to 7.6 L) worth of space in a 7.5 gallon (28 L) vessel. This allows room for the foam and gases that form during fermentation. If you don’t leave enough room, the pressure can build and pop the lid on the vessel, leading to contamination. Advertisement
3. 3 Prepare the lid. You need to make a hole in the lid that is the right size for a rubber grommet and airlock. Push the grommet into the hole. Then fit the airlock into the top of the grommet. Install a rubber gasket around the lip of the lid to form an airtight seal between the lid and the container.
4. 4 Clean and/or sanitize the equipment. The fermentation vessel (and rubber stopper for glass vessels or lid for a plastic bucket), airlock, and a large spoon should be cleaned and sanitized. Fill the fermentation vessel to the brim with a sanitizer, such as iodophor, that is made for brewing and winemaking, All these items are available at homebrewing and wine-making shops.

1. 1 Determine how much sugar (sucrose) to use. More sugar will result in more alcohol as long as the yeast can process it all. If you want a weaker batch (less alcohol) you can use less sugar. As a general guide, each packet of yeast will have directions that indicate how much sugar can be used.
   • If making two batches, be sure to use twice as much yeast (two packets).
2. 2 Dissolve the sugar. Mix the sugar into a pot of warm water to dissolve it. You can use tap water or bottled water. The water should be about 90 °F (32 °C). Use roughly 7 to 9 kilograms (15 to 20 lb) of sugar.
   • For a cleaner alcohol, use purified water.
3. 3 Pour the sugar solution into the vessel. When all of the sugar has been dissolved, carefully pour the sugar and water solution into the plastic bucket or glass carboy that you are using as a fermentation vessel. For a 7.5 gallon (28 L) vessel, pour 1.5 to 2 gallons (5.7 to 7.6 L) of solution. This sugar will be broken down by the yeast to produce alcohol.
   • It is not necessary to sterilize the sucrose solution before fermenting, but if desired this can be done by boiling the sucrose solution for fifteen to twenty minutes. Take into account that some of the water will evaporate, so add a little more water before boiling.
4. 4 Add the yeast. Open the yeast packet and dump the yeast into the sugar water solution. If using a plastic bucket, stir to get an even mixture. Use a sanitized, dry funnel to help prevent a mess when adding the yeast to the narrow opening of a carboy.
   • Use one packet of yeast. More yeast can speed up the process, but it will not lead to a better yield of alcohol.
   • Do not put the yeast into the sugar water until it has cooled. If the water is too hot it will kill the yeast.
5. 5 Wait one day. In the first days of fermentation, the yeast will expend most of its energy multiplying itself. Since this process requires oxygen, leave the lid off for the first 24 hours. If you cut off oxygen to the yeast immediately, the fermentation process will take much longer and may proceed sluggishly.
6. 6 Affix the lid to the bucket. If using a plastic bucket, tightly push the lid onto the bucket so that an airtight seal is formed. This may be somewhat difficult and may require some leverage. An airtight seal is necessary for proper fermentation.
   • Fermentation is an anaerobic (lacking oxygen) process.
7. 7 Add water to the airlock. If you haven’t already, push the airlock into the lid if using a plastic bucket. If using a carboy, now is the time to push the airlock through a drilled rubber stopper and fit the stopper snugly in the mouth of the carboy. Add clean water or vodka to the inside of the airlock so that carbon dioxide can be released from the fermenting solution while air is kept out. The drop in available oxygen will cause the yeast to stop multiplying and start producing ethanol and carbon dioxide.
8. 8 Let the mixture ferment. Keep the ambient temperature 70 to 80 °F (21 to 27 °C). This temperature will promote optimum performance from the yeast. It should take about two to ten days for the yeast to produce alcohol. The time required will vary depending on the type of yeast used, and on how much sugar was added. It will take longer to completely ferment more sucrose.
9. 9 Stop the process. The airlock will bubble a lot during active fermentation. The bubbling will slow as fermentation slows, and stop completely when all or most of the sucrose has been fermented. If you are unsure, leave the batch for another day or two. Once the fermentation is over, it is time to purify the alcohol.

1. 1 Clarify the fermented alcoholic liquid. After fermentation is complete, use a fining agent such as isinglass to remove suspended yeast and other material that may be present. Try to find isinglass that doesn’t contain sulphites, as some people are allergic to sulphites.
   • Use 0.5 to 1.0 gram of isinglass per 5 gallons (19 L) of batch.
2. 2 Siphon or pour off the alcoholic liquid. Siphon or carefully pour off the liquid into a glass carboy or other airtight container such as a cornelius keg. Leave the unwanted sediment behind in the fermentation vessel. You can also pour the liquid through a pad or membrane filter, such as a wine filter, to further clarify the liquid and remove residual yeast. Bottle the alcohol to preserve it.
   • Don’t store the alcoholic liquid in a carboy for more than a month as it can become oxidized over time.
   • Filter through a carbon filter if desired. Use a food-grade carbon filter to remove unwanted volatiles to further purify the alcohol. If flavors were added before this point, don’t use the carbon filter because it will most likely strip out the flavors.
3. 3 Drink responsibly. Add your alcohol directly to jungle juice or add liqueur flavorings. You can also age the alcohol in sealed bottles to improve the flavor, especially if making liqueurs. New bottles can be found at home brewing shops.
   • Reuse liquor bottles, wine bottles, and beer bottles, or use mason jars.

• Question How can I add flavor to alcohol? Tom Blake manages the bartending blog, craftybartending.com. He has been a bartender since 2012 and has written a book named The Bartender’s Field Manual. Professional Bartender Expert Answer Infuse the resulting mix with any ingredients you like. Add sugar to make it a liqueur. For instance, add strawberries and extra sugar to the mix and let it ‘steep’ for a few days, similar to how you would with tea.
• Question Is this legal? Would it be classified as moonshine? Anthony Kolka Community Answer It’s legal if you don’t sell it or distill it. it is illegal to distill alcohol without having either a “distilled spirits permit” or a “federal fuel alcohol permit” in the US.
• Question Does it give off a smell while making it? It can give off a couple of smells. Sometimes, if the yeast isn’t wine yeast and it’s just regular bread yeast it can give off a rotten egg smell but that goes away when it’s done fermenting.

• If the fermenting bucket is sealed without an airlock to vent the fermentation gases, the bucket will explode and most likely make a huge mess.
• You can substitute soda for fruit juice.
• The optimum temperature of yeast cells to anaerobically respire at is actually 38C°.

Advertisement Article Summary X To make alcohol from common table sugar, you’ll need a carboy, an airlock, a pot, yeast, sugar, and water. Before you get started, sanitize all of your equipment so bacteria doesn’t ruin your batch. Then, measure out 1 ¼ cup (.25 kg) of granulated sugar for every 1 quart (1 liter) of water you want to use for your alcohol.

1. The more water and sugar you use, the more alcohol you’ll make.
2. Fill the pot with your desired amount of distilled water, then heat the water on a stovetop until it’s hot.
3. Gradually add the sugar to the water, stirring continuously until it’s all dissolved.
4. Next, take the sugar water off of the heat and let it cool to room temperature.

Funnel the sugar water into the carboy. Now prepare the yeast by mixing it with warm water per the instructions on the packet. Use 1 packet of yeast for every 2 quarts (2 liters) of water you’re using. Funnel the activated yeast into the carboy and stir everything thoroughly.

Secure the carboy with your airlock. The airlock will allow CO2 to escape from the carboy while preventing oxygen from getting in and disrupting the fermentation process. Finally, store the carboy in a dark, cool place for about 1-2 weeks. You’ll know the fermentation process is finished when you no longer see movement inside of the airlock, meaning no more CO2 is being emitted.

If your alcohol is cloudy, you can add a clarifying agent to clear away the suspended yeast. Siphon or pour your alcohol into a sanitized glass container for storage, leaving behind any sediment.

What temperature do you pitch yeast in Celsius?

Brewer: Jesse Williams, New Albanian Brewery in New Albany, IN – Monitoring temperature and responding appropriately to shifts throughout the brew cycle, particularly during the fermentation period will make or break your beer. So, my first tip, if you do not already possess one, get yourself a thermometer! A typical bi-metal meat thermometer will suffice, but many floating and digital models are also available.

Whatever thermometer you get, calibrate it to 32 ºF (0 ºC) degrees in 50/50 ice and water, and you’re ready to go. Yeast lives and dies according to the temperature, so be aware of yours! Most strains of brewer’s yeast can survive temperatures in excess of 110 ºF (43 ºC), but it’s not a good idea to let your brew get anywhere close to that extreme.

Unless your yeast strain is geared for warmer temperatures, pitching should be commenced around 70 ºF (21 ºC), with plenty of oxygen incorporated. A cold water fed garden hose and a wort chiller should get you close to this temperature. A little clear thinking can lessen the fluctuating fermentation temperatures common in homebrewing.

Never under any circumstances leave fermenting beer where the sun can get to it. UV light can skunk a hoppy beer while it’s still fermenting. A dark basement or closet that stays within a reasonable temperature range is a decent place. Yard sales and classified ads can also yield serviceable old refrigerators for the garage that make temperature controlled brewing much more convenient.

Home refrigerators always have some temperature fluctuation, but a small standing thermometer can give you a good idea what’s going on in there. Any working refrigerator has less temperature fluctuation than the floor of your garage. All right, so you still can’t control your temperatures and don’t feel like spending the money on your grandmother’s old refrigerator.

Does fermentation require darkness?

Place the Jar in a spot about 70ºF (not much above 72ºF and not much below 68ºF) and ferment for the time specified. Desirable LAB flourish optimally at about 70ºF while culturing most vegetables. Temperatures too low will slow down the fermentation process, and temperatures too high will either kill them, causing the fermentation process to proceed too quickly, and/or cause undesirable softening of the vegetable.

• Each species of LAB has an optimal temperature range (yogurt LAB like 105-112ºF).
• Follow the temperature suggestions in the recipe for optimal results.
• Cover the Jar with a dark kitchen towel.
• Lactic acid-producing bacteria (LAB) (the bacteria that do the work of fermentation) flourish in the dark, and light kills them.

UV Light in the amounts that penetrate the Jar seem to be beneficial to yeasts, and is to be avoided. Yeast, while not necessarily harmful, really interferes with the flavors and texture of a ferment. Wrap the Jar with a dark kitchen towel, or another light-blocking material, and set it in a location in the kitchen where the sun does not shine directly.

Be sure to keep the top of the Airlock uncovered to allow pressure to escape thru the tiny holes in the Airlock cap. Move the Jar to cool or cold storage at the indicated time. The time frames given are a guideline, When the bubbling looks like it has stopped, it is time to move it to cooler storage. Don’t move it to cool or cold storage while the ferment is still producing bubbles; likewise, don’t leave it at room temperature much longer when no more bubbles are being created.

I like to peek at my ferments a few times each day. There is something so satisfying about checking on the bubbles! To check for bubbles, I remove the towel that covers the Jar, slide the Jar towards me on the counter, and without lifting the Jar, grasp the lid and neck of the jar (without disturbing the Airlock) and rotate the jar back and forth a few times.

How do you know if you killed your yeast?

Instagram: jbatthegratefulgirlcooks – Trying to figure out if your dry yeast is still good for baking? It’s really simple to learn how to test yeast for viability in about 10 minutes.

• 2¼ teaspoons dry yeast
• 1 teaspoon granulated sugar
• ¼ cup water (heated to 110°F)

1. Measure out 2¼ teaspoons of dry yeast (active, quick rise, etc.) into a small bowl. Add 1 teaspoon of granulated sugar, and combine the two ingredients.
2. Now you will need to add warm water to the yeast and sugar, BUT there is a catch! The water needs to be at 110°F. to activate the yeast. If the water is too hot, it will kill the yeast. The way I do it is to bring some water to almost a boil, then pour out ¼ cup of it into a measuring cup. Let let the water slowly drop in temperature until it registers 110°F. on a digital thermometer. As soon as it hits 110 degrees, pour the water into the yeast mixture and stir well, to combine. Once combined, set the bowl aside for 10 minutes.
3. After 10 minutes, check on yeast. You should have a bubbly mixture that smells very “yeasty”. If bubbles are non-existent, the yeast is unfortunately dead as a doorknob. IF the yeast is bubbly and has a yeasty aroma, then it can still be used for recipes that call for yeast. Discard your yeast experiment, and use unused yeast to bake away!

What temperature do you add yeast to must?

How To Add Yeast To A Wine Must is an essential ingredient of any wine recipe. It is the critical ingredient that does all the work. Wine yeast consumes the sugars in the wine must and converts them into alcohol and CO2 gas. Without the yeast you would have no wine.

1. There are three different ways to add yeast to wine must.
2. Each method has its own advantages and disadvantages.
3. Here’s a brief overview of each of them: Add The Yeast Directly To The Wine Must: This is the most common method.
4. Simply open the packet of wine yeast and sprinkle it directly on top of the wine must.

There is no reason to the stir the yeast into the liquid. It will dissolve into the wine must just fine on its own. Sprinkle the yeast and let it be. The obvious advantage to this method is that it takes no effort. The disadvantage is that you do lose some of the yeast’s ability to ferment effectively at the very beginning of fermentation.

1. The result is a delay in the startup of fermentation – usually a matter of 3 or 4 hours.
2. Re-hydrate The Yeast.
3. Then Add To The Wine Must: The wine yeast that you get in little packets has been dehydrated.
4. All the moisture has been taken from the cells to make them inactive while in storage.
5. Re-hydrate means to add water back to the yeast.

When this process is done before adding the yeast to the wine must, you get a fermentation that takes off more quickly. It’s no coincidence that this is the method you will find directed on the side of most packets of wine yeast. The producers of these yeast packets would prefer you use this method.

The problem is that if you do not follow the directions “exactly” you can easily kill the wine yeast. Typical wine yeast re-hydration directions will read something like: “Put the yeast in two ounces of water that is between 104°F. and 109°F. for a period of 15 minutes.” This method works well if you follow it without wavering in time or temperature.

But if you don’t use a thermometer to verify the water’s temperature, or if you leave the wine yeast in the water for longer than directed, you can easily kill most or all of the wine yeast. Make A Yeast Starter. Then Add To The Wine Must: This method is often confused with re-hydration, but it’s not the same thing.

Re-hydration is getting the wine yeast back to its original state by adding water with it. But a yeast starter is actually letting the yeast ferment on a small amount of must before adding it to a batch of wine. A yeast starter usually take one or two days to get going before it is add to the entire batch.

Making a yeast starter is fairly straight-foreword. If the wine must is already prepared you can use it as the starter. One pint of wine must in a quart Mason jar and a packet of wine yeast works perfectly for a five gallon batch of wine. If your batch is larger, multiply the starter’s size proportionately.

Add a 1/4 teaspoon of yeast nutrient along with the yeast packet and cover it with a plastic wrap secured with a rubber band. Prick a pinhole in the plastic wrap to allow the gasses to escape. Regardless of the starter size or how it was made, you want the wine yeast to maximize its level of activity before adding it to the wine must.

You will see the yeast starter begin to foam up. I usually tell people to pitch the starter into the wine must once you see this foaming start to slow down. In other words, once the foaming has peaked. This is usually 12 to 18 hours after starting. When you make the yeast starter you can sprinkle the packet of yeast direction into it, but the purist will re-hydrate the wine yeast in water, first, before doing so.

1. The advantage with the method of adding yeast to a wine must is that you will get the quickest and most thorough fermentation.
2. Your yeast will also be under little stress, so the chance of the yeast producing any off-flavors is very minimal.
3. The disadvantage is that it is more work, and you do need to plan ahead since the starter needs a day or two to get going.

How you decide to add yeast to your wine must is entirely up to you. Any of these methods will work. Just consider the advantages and disadvantages of each one, and go with what works best for you. —– : How To Add Yeast To A Wine Must
