Diammonium Phosphate (DAP) is a common yeast nutrient which is a great source of nitrogen for yeast. Use 1/2-3/4 grams per gallon (1/2 tsp per 5 gallons) of must to aid yeast and help reduce later problems with hydrogen sulfide. There is a superior nutrient regimen (using Go-Ferm and Fermaid K) for wine making: A rough approximate of weight is 1 tsp = 3.1 grams.

How much yeast do I need? – Simply multiply the number of gravity points by the multiplier you selected above, and then multiply by your batch size in gallons. Five gallons (19 liters) of 1.050 ale will need (0.007 packs per gallon per gravity point) × (50 gravity points) × (5 gallons) = 1.75 liquid yeast packs.
How much yeast nutrient should I add for beer?
Product details – Yeast Nutrient is a mixture of diammonium phosphate and food-grade urea that nourishes yeast, ensuring that it remains healthy throughout fermentation. Add one teaspoon per gallon recommended for wine, mead, seltzer, and cider.
How many grams of yeast nutrient per gallon?
Fermax Yeast Nutrient,1 lb > > > > Fermax Yeast Nutrient,1 lb $ 9.59 In stock (available) Fermax Yeast Nutrient is a proprietary yeast food in powder form. Containing diammonium phosphate, magnesium sulfate, yeast hulls, B vitamins and calcium salts, it supplies all important nutrients that yeast require for a healty fermentation. It is not usually necessary to add nutrients to a fermenting grape must, but nearly all wineries do so because without sophisticated laboratory testing it is impossible to tell which grape musts are nutrient deficient prior to the start of fermentation.
Thus, in order to avoid any potential problem, the supplement is almost always added. It is recommended that it definitely be used in making fruit wines, as they are usually deficient in one or more nutrients. The use of a proper nutrient will also minimize the possibility of sulfide formation during fermentation.
Typical use is between 1 and 4 grams (1 teaspoon) per gallon. Divided doses are recommended, with half added at the start of fermentation and the remainder added midway through fermentation. : Fermax Yeast Nutrient,1 lb
Can you use too much yeast nutrient?
Yeast assimilable nitrogen – The major yeast nutrient we are concerned with in the grape is yeast assimilable nitrogen. YAN is composed of inorganic nitrogen (ammonia) and organic nitrogen (primary amino acids). It is important to know the YAN level in fruit prior to fermentation so that you can make appropriate additions.
- Often, by the time you notice a problem fermentation, it is too late to add nutrients.
- This is because increasing ethanol concentrations hinder amino acid uptake late in fermentation.
- You also do not want to add excessive nutrients at the beginning of fermentation.
- Large additions of nutrients early in the ferment may lead to overvigorous fermentations and alter the aroma compounds produced by the yeast.
In addition, residual nutrients in the wine may contribute to microbial spoilage during aging. So, how much YAN do you need? It depends. The general recommendation is between 120 and 220 mg/L for a 21 Brix must. If you have higher Brix must or are using a high nutrient demand yeast strain, you may want to consider higher YAN levels.
How much yeast do I need for 5 gallons of must?
Each 5 gram packet is enough to start 5 gallons of wine by direct addition. Packets may be stored at room temperature or in the refrigerator.
Can you put too much yeast in beer?
, How much yeast does it take to make beer? The yeast you pitch into your wort is made up of billions of individual yeast cells. Ideally each cell is alive and ready to begin fermenting as soon as you add it to your cooled and oxygenated wort. The individual cells are far too small to see and count without a microscope, but it is important to get the number right.
Imagine you were planting a field of corn. You want to plant exactly the right amount of seeds to optimize your yield: if you plant too few, you will end up with less corn and more open space for weeds to occupy. If you plant too many, the plants will crowd each other and may exhaust the nutrients in the soil, reducing the yield.
Exactly the same is true for yeast: add too little and fermentation will take a long time to get started, increasing the risk that bacteria will outcompete the yeast. Add too much, and the yeast will turn quickly to fermentation without having made many new yeast cells.
- Since all those growing yeast cells release complex compounds like esters, the finished beer will have a less complex flavor and aroma.
- Brewers use formulas to figure out how many yeast cells to add.
- They are slightly different depending on the type of beer being brewed, but all have the following factors: number of yeast cells per milliliter of wort per degrees Plato of the wort.
Degrees Plato is a measurement of the specific gravity of the wort, which in turn is simply a measurement of how much sugar and other compounds are dissolved in the wort. For comparison’s sake, the specific gravity of water is (by definition) equal to one.
- The specific gravity of, say, molasses, is around 1.4.
- Most worts have a specific gravity of about 1.04 to 1.05 — in other words, about 4-5% higher than pure water.
- Pitch rates are calculated to add enough yeast to reproduce for a few days with that amount of nutrients before turning to fermentation.
- The fermentation, therefore, will take place with many more yeast cells than were originally added, and those new yeast cells will be young and healthy, leading to a vigorous fermentation.
Companies that sell yeast to home brewers grow it from pure cultures under standardized conditions and provide it in packets that contain the correct number of yeast cells to inoculate 5 gallons of standard wort (that’s about 100 billion yeast cells!).
- Buying new yeast for each batch of beer ensures that you know exactly how many cells you’re adding, and that the cells are at the right life stage and healthy.
- However, it is also possible to re-use — or re-pitch — yeast from batch to batch.
- After all, not only are most of the original yeast cells still alive, but they will have budded off several generations of new yeast cells.
The risk, however, is that the yeast that is left at the end of fermentation is not exactly the same as the yeast you started with; along with young, newly budded cells, there will be dead yeast cells, cells that have already budded off so many offspring that they can no longer reproduce, and cells that have undergone various mutations.
Furthermore, the yeast that was originally pitched was not genetically identical, but contained billions of individuals that each differed very slightly from each other. The genetic variants that were most successful in the particular conditions of that fermentation will be slightly more frequent in the next generation; that’s evolution at work.
Over time, the character of the yeast can change substantially. Judging how much of the leftover yeast to re-pitch, and how often, is something of an art. In general, it is recommended to re-pitch no more than 5 to 10 times. :, How much yeast does it take to make beer?
How much nutritional yeast should I use?
– You should keep nutritional yeast in a cool, dark place to preserve its vitamin content. Furthermore, seal the container tightly to keep moisture out. When properly stored, it can last up to 2 years. Here are a few uses for nooch:
as a seasoning for popcorn, pasta, salad, or casserole dishesas an umami flavor in soups, stews, or chilias a savory, cheesy flavor in vegan saucesas a thickener for soups and saucesas an ingredient in smoothies as a pet food additive
Serving sizes for nutritional yeast depend on the recipe, but you typically use 2–4 teaspoons (5–10 grams). Summary Nutritional yeast is shelf-stable for up to 2 years when stored properly. You can add it to many foods for a nutty, cheesy, or savory flavor, as well as extra vitamin and mineral content.
How often should I add yeast nutrient?
Honey is an amazing thing, and it makes a fine alcoholic beverage, but it does have one little problem. Unlike grapes or barley, honey is a nutrient-poor substance. It lacks some of the necessary compounds and elements that yeast needs. What this means for mead-making is that if you try to ferment honey and water alone, the yeast will often become stressed, stop fermenting too soon and start producing undesirable off-flavors.
This commonly appears as burnt rubber or rubbing alcohol flavors in the young mead. Often these bad flavor compounds will diminish with time, but by treating your yeast well and keeping them healthy you can avoid them altogether. Here’s what you need to know about nutrients and mead. Honey especially lacks a source of nitrogen.
Mead makers counteract this by providing the fermentation with Diammonium Phosphate during the first few days. A simple nitrogen source such as this is usually called Yeast Nutrient. There are many other nutrients that yeast need in smaller quantities.
- Our Yeast Energizer is an excellent supplement to the Yeast Nutrient.
- Together they can supply everything that the yeast needs to keep going and stay healthy.
- For many years brewers just added all of the required nutrients at the start of fermentation.
- More recently it has become common practice to split the nutrients into smaller amounts and add them at intervals during the first few days of fermentation.
Spreading out the nutrients in this way is called “staggered nutrient additions”, and it helps keep the yeast healthy and reduce off-flavors. Our 5-gallon mead kits recommend adding 1/2 teaspoon yeast nutrient and 1/4 teaspoon yeast energizer at the beginning of fermentation and adding the same amounts once per day for the following 3 days.
Be careful when adding dry powders to fermenting mead! The sudden release of co2 can cause the mead to foam out of the fermentor. Removing a small portion of the mead to combine with the nutrients first can help, as can stirring to release co2 before adding the nutrients in. Following this method, you’ll have great success fermenting honey whether it’s your own recipe or a mead making kit,

Should you always add yeast nutrient?
What is usable as a substitute for Yeast Nutrient? –
Orange or lime peel. Lemon juice. A cup of strong black tea. A cup of chopped raisins. Grape nuts boiled in water, then strained and the liquid added to the must. Bread yeast is boiled in water for 15 minutes to kill it.
If you have been brewing for any time, you may have heard of yeast nutrients. It is a ubiquitous additive for many wine recipes but rarely in beer recipes. Several yeast companies produce their brand of yeast nutrients, but what exactly is it, and when should you use yeast nutrients.
Brew Mart will cover what yeast nutrients are and why you need them. Yeast Nutrients The health of the yeast is an important consideration when making homebrew beer, wine, cider or mead. After all, it is the main reason for alcohol production. Yeast is necessary for converting sugars to alcohol, but it is also imperative because it has a significant influence on the flavour of the finished beverage.
Yeast produces many different compounds when fermenting a beer or wine, significantly affecting the flavour. Wheat beer yeast, for instance, produces clove, banana and bubblegum like flavours, which is desirable for the most part, but if they are not healthy, they can have undesirable flavours.
Undesirable flavours to your homebrew from unhealthy yeast can contribute to tastes such as harsh alcohol flavours or buttery flavours from diacetyl or apple flavours from acetaldehyde. These are all symptoms of insufficient yeast cells or poor yeast health. Yeast Nutrients is an aid to the Health Of Yeast Cells.
When making beer, wine, cider or mead, add yeast nutrients to ensure that the building blocks required by the yeast are present. When yeast reproduces, they require nitrogen, amino acids, vitamins and fatty acids to produce new cells. If these components are not present when you add yeast to your wort or must, it can lead to problems at the start or during fermentation.
- What Is In Yeast Nutrient? Most blends of yeast nutrients contain a few different compounds; however, it is good to check the label to see what is in the mixture.
- Some yeast nutrients may only provide one thing, such as nitrogen.
- The most common ingredient found in yeast nutrients is Diammonium Phosphate.
Diammonium Phosphate is a salt that provides a source of free amino nitrogen (FAN). FAN is an ingredient in many yeast nutrient blends, and it is vital for yeast health. Malt has a large amount of FAN when making beer, so this nutrient is often not needed.
- Yeast Hulls : These are essentially dead yeast that acts as a source of lipids and fatty acids vital in providing new yeast cell production resources.
- Vitamins, Thiamin and Biotin : Yeast requires specific vitamins for cell growth and reproduction.
- These vitamins are added to nutrient blends to provide these critical ingredients.
When making country wine, Biotin, a B-vitamin, is recommended. Magnesium, Zinc : These ingredients are added to yeast nutrients to increase the cell count and magnesium aids yeast metabolism. Do You Need To Use Yeast Nutrients? Brew Mart always recommends using yeast nutrients if the recipe has them listed in the ingredients and sometimes even if it isn’t.
- There are a few examples where it is unnecessary, so let’s explore these.
- Is Yeast Nutrient Required In Beer Making When making beer, it does have a lot of the nutrition yeast needs.
- When producing a wort for beer, you create it with nutrient-rich ingredients like malted barley.
- Using malted barley means adding yeast nutrients is not necessary.
When you are brewing particular beers, there may be certain instances that adding yeast nutrients will be beneficial. The time to think about using yeast nutrients would be in some of the following cases: When Beer Is A Particularly High Gravity Beer : Each yeast strain has a certain tolerance for alcohol.
- Depending on the type you use, you may get closer to this tolerance, making it more challenging for the yeast.
- Adding yeast nutrients in beers over 8% ABV will help ensure the fermentation will not run into problems causing yeast stress and stalling.
- If Beer Production Uses A High Portion of Adjuncts : If the beer uses many adjuncts, particularly if a sizeable fermentable product comes from plain sugar.
Sugar alone has no natural nutrients for the yeast, so in cases where 25% or more of the fermentable materials come from adjuncts, yeast nutrients may be a good idea. Unless you are brewing a beer like this, using a yeast nutrient for beer making is unnecessary.
- Most wort is nutrient-rich and will contain everything needed to produce healthy yeast.
- Nutrients for Yeast Starters If you regularly make yeast starters, you may consider yeast nutrients.
- Increasing yeast cell numbers is intensive and requires plenty of nutrition to create new cells.
- Using a yeast nutrient with vitamins, nitrogen, zinc, and magnesium is very beneficial to aid the process and speed it up.
Yeast Nutrients For Wine, Mead & Cider Making Yeast nutrients become more vital for home winemakers and mead makers where the ingredients aren’t as nutrient-dense as malted barley and wheat. When making country wines where more than 90% of the fermentable sugars come from simple sugars, the yeast needs yeast nutrients to reproduce and thrive.
The same is valid for making mead. Honey is a simple sugar and will require a boost of nutrients for the yeast to ferment at its best. Brew Mart would recommend using yeast nutrients when making cider, wine, and mead in most instances. The homebrewer has no way of knowing what nitrogen is available in the ingredients they are using or what other micronutrients may be present.
A home test is unavailable to test these things. In contrast, beer makers have malt specifications to ensure something like FAN. How Much Yeast Nutrient To Use? Dosages of yeast nutrients are available on the package they come in, so always follow the advice and recommendations from the manufacturer.
Do you need yeast nutrient for beer?
The Oxford Companion to Beer Definition of yeast nutrients The Oxford Companion to Beer definition of Yeast Nutrients are compounds and elements that are essential to vigorous yeast health and viability. Brewers must ensure optimum yeast health to avoid slow or stuck fermentations, off-flavors, and other problems with beer.
- The key yeast nutrients are carbohydrates, amino acids, vitamins, and minerals.
- Malted barley naturally contains a balanced set of these, but high-gravity worts, especially those containing high levels of adjuncts in the form of refined sugars, may not be properly balanced, and yeast performance in these environments may be sluggish.
Yeast cultures that have been repitched many times may be particularly prone to inefficient uptakes of nutrients, especially in demanding environments. Many fermentations can be aided by the addition of yeast nutrient preparations, even in all-malt worts.
- Simple carbohydrates such as glucose, fructose, sucrose, and maltose and often maltotriose are easily metabolized by brewer’s yeast.
- Yeast cannot, however, assimilate higher polysaccharides (namely dextrins).
- Therefore, these stay in the finished beer.
- Amino acids, also referred as free amino nitrogen (FAN), are the yeast’s main nitrogen source, whereas yeast cannot metabolize peptides and proteins.
FAN is incorporated into new yeast proteins but the FAN levels influence the yeast’s fermentation performance. Especially for beers with high levels of alcohol, judicious additions of a nitrogen source may be indicated. Vitamins such as biotin, panthotenic acid, thiamine, and inositol are essential for enzyme function and yeast growth.
- Minerals including phosphate, potassium, calcium, magnesium, and especially zinc are crucial to yeast health and thus successful fermentations.
- Zinc can be deficient even in all-malt worts, because most of it tends to be lost during lautering.
- Extra zinc can be added in mineral form (ZnSO 4 or ZnCl 2 ), or it can be incorporated in inactive yeast for a more complete nutritional product.
German brewers technically adhering to the Reinheitsgebot, which does not allow the addition of mineral salts, have found many ingenious ways to ensure that their yeast gets the zinc it needs. These range from zinc fittings inside the kettle or lauter tun, zinc chains attached to the paddles in the mash mixer, or the old brewer’s trick of adding some live yeast to the kettle.
- Sometimes a block of zinc is simply hidden at the brewery; shavings will occasionally be taken from it.
- Weissbier fermentations are particularly susceptible to zinc deficiencies because wheat is rich in manganese, which can block zinc uptake by yeast cells.
- Finally, yeast needs oxygen to synthesize sterols and unsaturated fatty acids in the yeast cell membrane.
This, in turn, allows for ample cell divisions during the yeast’s aerobic phase. Yeast nutrients, judiciously applied, can speed fermentations and promote better attenuation, better flocculation, better yeast storage capability, and better overall beer flavor.
- As such they have become a standard part of the brewer’s husbandry of yeast.

Does yeast nutrient make a difference?
Although every product is different, here are some of the most common constituents of a good nutrient blend. Work with yeast (or microbiologists) for any appreciable length of time, and you’re bound to hear about the benefits of yeast nutrient. Added to a starter, nutrient helps promote healthy growth of the colony.
Diammonium phosphate (DAP) is a water-soluble salt that is often included in plant fertilizer to increase the pH of soil. It also delivers valuable nitrogen and phosphate to yeast cells. Wort is generally rich in nitrogen, but a little supplementation can help high-gravity beers complete fermentation. Phosphates also help ensure smooth fermentation of worts that contain large portions of non-malt adjuncts. Amino acids are necessary for creating proteins and for reproduction. Yeasts can actually make most of their own amino acids, but there are a handful, termed essential amino acids, that cells must pull in from the wort they’re in. If wort happens not to have enough for one reason or another, a little boost of yeast nutrient can help keep your yeast cells happy. Vitamins and minerals of all kinds—biotin, pantothenic acid, calcium, magnesium, potassium, and many others—are necessary for the reactions that create the compounds yeasts need to do their job. They also serve as catalysts in many of the reactions that take place during fermentation, and some even aid in flocculation and cell wall preservation. Zinc, which falls under the mineral umbrella is one of the less common essential minerals found naturally in all-malt wort. Zinc plays a vital role in the production of ethanol, which we can all agree is pretty key to the whole beer thing. Yeast ghosts, or yeast hulls, are basically the water-insoluble skeletons of dead yeast cells, and they’re included in many nutrient formulations, as well as available on their own. Live yeast cells cannibalize these dead cells and feed off the nutrients they contain. Gross, eh?
In most standard gravity all-malt worts, you need not worry about yeast nutrient (except perhaps zinc), but it can’t hurt to throw in a pinch or two for good measure. I usually don’t bother with nutrient in the main wort unless I’m brewing high-gravity or high-adjunct beer, but I always add a little to my yeast starters.
You’ll still make great beer without nutrient. But if you find that your beers seem a little underdone, for lack of a better term, try a pinch or two of nutrient. It might just be the boost your yeast cells need. Go beyond smack packs and yeast starters with Craft Beer & Brewing Magazine®’s online class: Advanced Yeast Management.

Will adding yeast nutrient help a stuck fermentation?
How to Restart a Stuck Beer Fermentation It doesn’t happen often to homebrewers, but every once in while, a beer fermentation stalls out. It’s called a stuck fermentation. Why does this happen? Any fermentation that is stressed has a chance at getting stuck.
Sources of stress can be a lack of yeast nutrition, being too high or too low, or the yeast itself is not of good enough quality or quantity to complete the fermentation. One of the best things you can do is to avoid a stuck beer fermentation in the first place: build a healthy, use yeast nutrient, and keep the fermenter within the recommended temperature range for the yeast you’re using.
When all else fails, however, you may need to take measures to resolve a stuck fermentation. How to Restart a Stuck Beer Fermentation
Make sure you actually have a stuck fermentation. Check the hydrometer readings on your beer at least three days apart. Make sure you’ve cleared the hydrometer sample of bubbles, which can affect the reading (just pour the sample a few times between a couple beer glasses). If the reading hasn’t changed and you’re still a ways (more than 5 points) from your estimated final gravity, proceed. But if the reading has changed, just give the beer more time. On the other hand, if the hydrometer reading is static and within about five points of your final gravity, fermentation may just be complete.
Check the fermentation temperature, The yeast may have stalled because the fermentation temperature is too cold. Try moving the fermenter to a warmer area. A five-degree rise in fermentation temperature may convince the yeast to “wake up” and get back to work.
Rouse the yeast, You can also try mixing the yeast back into solution to restart a stuck beer fermentation. Swirl the fermenter or gently stir the beer with a sanitized spoon. Take care not to slosh or stir too vigorously – you don’t want to introduce air into the beer this late in fermentation.
Add yeast energizer. contains nutrients that will often restart a stuck beer fermentation. Start with 1/2 tsp. per gallon, adding directly to the fermenting beer. More can be added later if your fermentation needs an extra boost.
If none of the above work, try racking the beer into a new fermenter and pitching a fresh batch of yeast. Remember to sanitize all of your equipment before doing so.
Stuck fermentations may not happen very often, but knowing what to do when one comes your way will help make sure you don’t miss out on a tasty batch of homebrew. How do you usually restart a stuck beer fermentation? ———————————– David Ackley is a writer, brewer, and craft beer marketing consultant.

How much yeast do I add to 5 gallons of mash?
For a 5 gallon mash: (201) –
5 gallons soft, filtered water. 7 lbs (3.2kg) cracked corn.6-8 pieces/kernel is the proper crack. If using bird feed, make sure it is perishable, or in other words is free of preservatives. 7 lbs (3.2kg) of granulated sugar. 1 tbsp yeast (distillers yeast if available.)
How much yeast do I need for a 5 gallon batch of mead?
I recommend 1-2 grams of nutrient per liter of must and 10 grams of yeast per 5-6 gallon batch.
How much yeast do I need for 1 Litre of beer?
Grams per Liter Approach – This approach is based on grams of yeast per liter of wort and coincides with the dosage instructions found of the Fermentis yeast analysis sheets. For all but there lager yeast, Fermentis recommends a dosage of 50 to 80 grams per hectoliter of wort. We can change this to liters easily by dividing by 100, which gives us 0.5 to 0.8 grams per liter.
Again, 19 liters in 5 gallons of beer, so: 0.5 x 19 = 9.5 grams 0.8 x 19 = 15.2 grams If you’ll notice, at 0.5 grams we get very close to the same amount as we did assuming 20 million viable cells, which I’m guessing is what whoever came up with that rule of thumb was working from. I only point this out to show there is some amount of consistency between the two approaches.
And we could even figure out the dosage of a single 11.5 gram pack.11.5 / 19 = 0.6 grams per liter; which falls within the manufacturers dosing rates, but using two packets (23 grams) puts your pitch rate at 1.2 grams per liter which is actually close to the upper range of what commercial breweries pitch.
What temperature kills yeast in beer?
At what temperature do most yeasts die off? As a general rule, yeasts will die between 105 and 108 F. During fermentation this terminal temperature will lower as a result of alcohol presence. As a wine approaches 10% alcohol content, the terminal temp for yeasts can be as low as 90F.
How long can beer sit before adding yeast?
Author Topic: Delay in pitching yeast (Read 5165 times) – I am doing a last minute brew and my local HBS didn’t have the yeast I need. Is it ok if I brew in the morning, go find the yeast at another store and pitch it later in the day? Like a few hours after cooling the wort? What’s the longest I can wait to add the yeast? Does the holding temp of the wort matter? I could probably find a way to keep it cool if need be. Logged The longer you wait to pitch the yeast the more chance there is for critters to get a footing and funkify the beer. You will likely be ok if it’s only a couple of hours, but you really want fermentation to get going as soon as possible after the wort is cooled from the boil to avoid infection.

How many grams of yeast for 5 gallons of mash?
How to Prepare Mash › › How to Prepare Mash AMOUNT Use this ratio – 2 to 4 grams of dried yeast for every gallon of mash. The foamy, rocky head of yeast called kraeusen, should form during the first four hours of fermentation. It could lag up to 24 hours which should be fine. You have to pitch in some more yeast if it takes longer than a day to form,
The ” 100 grams of dry yeast per 5 gallons ” rule only applies to a pure sugar mash where you aim to turn it into vodka or as a base spirit for liquors. with more than 4 grams of yeast per gallon will effect undesirable sulfur flavors that can be difficult to get rid of. However, take note that over pitching would be preferable than under pitching yeast.
Over pitching can get you some off flavors but they can be eliminated with a lot of exposure and secondary ferment. While, under pitching results to a long lag time that makes the mash at risk of contamination. NUTRIENTS During the fermentation, we want to keep the yeast happy so it can make the most out of our sugar.
So we keep them fed and provided with proper nutrition. By saying that, nitrogen must be present! DAP (Diammonium phosphate) is usually used as yeast nutrient. Ammonium salts or ammonia are also great sources of nitrogen. A sugar wash typically needs 2 ml. of ammonia per liter of mash. Also, do not supply the yeast with excessive nutrients, it won’t push them to work faster anyway.
It might even kill them. pH Your yeast requires a slightly acidic environment to survive and multiply, which also helps restrain bacterial contaminants. It is advisable to maintain the mash a pH of about 4.0-4.5 before fermentation. Citric or lactic acids will help you do that.
Lemon juice can be a great and cheap alternative! You can always double-check the pH using pH papers. TEMPERATURE Temperature is another key to successful alcohol yield. At some point, the temperature the yeast is submitted can degrade the flavor of the final distillate. When using ale yeast to make, the temperature should be between 60 to 70 F.
Lower than this range will hold back the yeast from converting sugar which makes the mash at risk of infection. Higher temperature will effect stress reactions on the yeast that causes higher alcohol formation and ester. The result is an undesirable solvent-like flavor that can sting the taste of the final alcohol.
Using a water bed heating pad, wrap the fermenter around and attach the thermostat to the side of it. Wrap them all up with a blanket. Keep the mash vessel inside a hot water cupboard. Submerged the fermenter in a drum filled with warm water and then secure an immersion heater to keep the water warm.
