How to Use Turbo Yeast For Alcohol – There are a couple of things you should know about turbo alcohol yeast. First off, all strains of yeast go dormant when at a certain temperature too cold for them to thrive. They will become inactive at a certain temperature too hot for them to survive.
All our packets of yeast come with instructions on how much water and sugar to use with the yeast. As well as, what temperature it should stay at while fermenting. You should expect to not have your mash go above 80F (27C) for most of our yeasts. Don’t dip below 65F (18C). Another important note is that the whole process of fermentation happens when the yeast runs out of oxygen and needs the dextrin in the sugars in order to keep “surviving”.
With this said, make sure when fermenting, your bucket lid stays completely sealed on the bucket, and your airlock is snug and in place. It should take no more than 2 days for your airlock to start bubbling as carbon dioxide releases. If your airlock is not bubbling, something might be wrong with the fermentation.

What is the best yeast to use for fruit moonshine?
What Type of Yeast To Use For Fermenting Fruit Mash? – Yeast selection is very important, I would recommend you use k1v-1116 to ferment fruit mashes. I wrote an article on : Yeast selection for fermentation of sugar, grain and fruit wash. It talks about selecting the proper yeast for fruit, grain mashes and sugar washes.
What is the best yeast for distilling spirits?
What Distiller’s Yeast Is Best For Different Distillates? – It seems we answer this question multiple times a day. Although distiller’s yeast are normally labeled as being more appropriate for whiskey, rum, vodka or whatever you are making, our experience has shown that one distiller’s strain can make multiple types of quality distillates.
At Wilderness Trail Distillery for example, we use the same yeast strain to make Bourbon whiskies as we do for our rum and vodka. Ferm Solutions, as well as other companies that supply yeast, have already selected excellent distilling strains; so the slight nuances from one strain to the next are really up to the producer to decide which one is the best for a particular application.
Out of the nine distiller’s yeast strains Ferm Solutions offers, you could pick any one to start with and you would be satisfied with the resulting distillate–no matter which spirit you are making. Then, once you establish a baseline on performance and flavor, you might choose to switch to a different strain and see for yourself what slight changes that will make in your final product. If we were making beer, then there would be a very specific strain we’d use depending on if you wanted an ale, lager, pilsner, or seasonal (a.k.a saison) beer, plus what level of attenuation or flocculation you desired (this just means whether or not yeast cells sink to the bottom or remain colloidal in the beer).
Out of the nine distiller’s strains available from Ferm Solutions, we probably use the FermPro 927 (FP927) the most. This strain has excellent temperature tolerance and can ferment to completion in as little as two days, producing an award-winning distillate.921, 917, 900, 048 and FP1 are also excellent choices.
Depending on your desired flavors, costs, and process, our experts at Ferm Solutions can walk you through which would be best for your unique distillery’s needs.
What kind of yeast is used to make alcohol?
1. Introduction – Fermentation is a well-known natural process used by humanity for thousands of years with the fundamental purpose of making alcoholic beverages, as well as bread and by-products. Upon a strictly biochemical point of view, fermentation is a process of central metabolism in which an organism converts a carbohydrate, such as starch or sugar, into an alcohol or an acid.
For example, yeast performs fermentation to obtain energy by converting sugar into alcohol. Fermentation processes were spontaneously carried out before the biochemical process was fully understood. In the 1850s and 1860s, the French chemist and microbiologist Louis Pasteur became the first scientist to study fermentation, when he demonstrated that this process was performed by living cells.
Fermentation processes to produce wines, beers and ciders are traditionally carried out with Saccharomyces cerevisiae strains, the most common and commercially available yeast. They are well known for their fermentative behavior and technological characteristics which allow obtaining products of uniform and standard quality. Central metabolism of fermentation in yeasts. The schematic chemical equation for the production of ethanol from glucose is as follows: C 6 H 12 O 6 ( glucose ) ⟶ 2 C 2 H 5 OH ( ethanol ) + CO 2 ( carbon dioxide ) Under absence or oxygen-limited conditions, ethanol is produced from acetaldehyde, and two moles of ATP are generated.
What is the best yeast for high alcohol content?
When brewing high gravity beers (i.e. high alcohol beers), the beer yeast needs to work a little harder to convert the extra sugar into alcohol. Not all beer yeast strains are cut out for the job. Some get tired, some can’t handle the extra booze. (Sounds like some people I know!) Here are five beer yeast strains to consider using when brewing high gravity beers. High Gravity Yeast Strains
Wyeast 3787: Liquid Beer Yeast: Trappist High Gravity – Wyeast 3787 is great for brewing high gravity Belgian style beers such as Dubbels, Tripels, and Belgian Strong Ales. This beer yeast strain tolerates alcohol content up to 11-12% ABV or higher and produces the fruity flavors and aromas characteristic of Belgian ales.
Wyeast 1388: Liquid Beer Yeast: Belgian Strong Ale – Wyeast 1388 is another good option if brewing high gravity Belgian ale beers, especially Golden Strong Ales. It can tolerate up to about 12-13% ABV.
Mangrove Jack’s: Craft Series Beer Yeast / Workhorse / M10 – Mangrove Jack’s Workhorse can handle up to 9% alcohol by volume and is useful for a wide variety of beer styles. Its clean flavor profile will work well for many American and English ales.
Wyeast 1728: Liquid Beer Yeast: Scottish Ale – Neutral and clean at the recommended temperature range, Wyeast 1728 is ideal for a malty Scotch ale, but it also works well for Barleywine, Old Ale, Russian Imperial Stout, and other big beers. It’s tolerant up to about 12% ABV.
Red Star Pasteur Champagne Yeast – When going where a normal high gravity beer yeast won’t (say, higher than 12% ABV), a champagne or wine yeast can help reach those higher levels of alcohol content. If going for a super high gravity beer, pitch a standard beer yeast strain for the primary fermentation, then add more fermentable ingredients, such as simple syrup or dissolved candi sugar, along with a pack of champagne yeast during secondary fermentation to achieve that higher alcohol content.
Tips for Brewing High Gravity Beers
As important (if not more so) than picking the right beer yeast strain, is pitching enough healthy yeast to completely ferment the wort. A beer yeast starter will help ensure that there are enough yeast cells to get the job done. Use a yeast pitch calculator to figure out how many packets of yeast or the volume of yeast starter you need.
Also use yeast nutrient and be sure to aerate the wort well prior to pitching the beer yeast.
If you’re trying to get above ~10-12% alcohol by volume, consider adding more fermentable ingredients to the secondary fermenter, combined with an additional yeast pitch using a different yeast strain.

Another possible source of methanol in traditionally fermented alcoholic beverage is the fermenting microbes. The ethanol fermenting yeast S. cerevisiae dominated traditional fermentation followed by Lactobacillus (Table 1 ). Jespersen ( 2003 ) also observed this trend in African indigenous fermented beverages and foods.
- Saccharomyces cerevisiae have been used as catalysts for the production of ethanol for thousands of years.
- But recent studies have shown that there are different strains of S.
- Cerevisiae involved in traditional ethanol fermentation (Hayford and Jespersen 1999 ; Jespersen 2003 ; Kuhle et al.2001 ; Pataro et al.2000 ; Guerra et al.2001 ; Ezeronye and Legras 2009 ).
The big question is ‘have the traditional ethanol producing yeast evolved into the production of methanol in addition’? Professor Benito Santiago, University of Spain (Personal communication, July 2015) opined that some years ago, methanol at low concentration was desirable in beer and wines.
- However, we were unable to find literature confirming this claim.
- Pectins are a group of heterogeneous polysaccharides found in the intercellular regions and cell walls of most fruits and vegetables (Siragusa et al.1988 ), with its greatest abundance in citrus particularly orange, grape, limes and lemons (Siragusa et al.1988 ).
Citrus contains 7–10 % pectin (Siragusa et al.1988 ). Chaiyasut et al. ( 2013 ) compared pectin levels in fermented beverage containing Morinda citrifolia (9.89 %) with that of other fruits including guava (4.36 %), tomato (0.3 %), apple (0.5 %), carrot (0.8 %) and cherries (0.4 %).
- During ripening, pectin in fruits is broken down by PME resulting in the formation of methanol (Chaiyasut et al.2013 ; Micheli 2001 ).
- However, pectin has not been reported in palm wine.
- Plant cell wall degrading enzymes including pectinases are ubiquitous among pathogenic and saprophytic bacteria and fungi (Prade et al.1999 ).
Pectin enzymes are widely distributed in nature and are produced by yeast, bacteria, fungi and plants (Sieiro et al.2012 ). Methanol is a major end product of pectin metabolism by microorganisms (Schink and Zeikus 1980 ). Human colonic bacteria, Erwinia carotovora is able to degrade pectin releasing methanol (Siragusa et al.1988 ).
- Anaerobic bacteria, particularly Clostridium butyricum, Clostridium thermocellum, Clostridium multifermentans, and Clostridium felsineum produce methanol from pectin (Ollivier and Garcia 1990 ).
- Schink and Zeikus ( 1980 ) reported various pectinolytic strains of Clostridium, Erwinia and Pseudomonas,
Dorokhov et al. ( 2015 ) listed at least 20 species of human colonic microbes capable of producing methanol endogenously. The authors in a comprehensive review presented at least five different pathways of methanol synthesis in humans and four pathways of methanol clearance from the body and they also demonstrated the presence of gene regulation in methanol synthesis.
- Readers are advised to consult this literature for details on metabolic methanol in human systems.
- Pectinolytic enzymes are classified into esterases and depolymerase (lyases and hydrolases).
- Hydrolysis of pectin by lyases produces oligo- or mono-galacturonate, while hydrolysis of pectin by esterases produces pectic acid and methanol (Sieiro et al.2012 ).
Some authors have identified strains of Saccharomyces that produces the three types of pectinolytic enzymes namely pectin methyl esterase (PME, EC: 3.1.1.11), pectin lyase (PL), and polygalacturonase (PG) (Gainvors et al.1994a, b ; Naumov et al.2001 ).
Fernandez-Gonzalez et al. ( 2005 ) genetically modified S. cerevisiae strain having pectinolytic activity. Analysis of S. cerevisiae among many traditional fermented beverages in Africa shows that they vary according to the location and types of substrates (Jespersen 2003 ). Strains of S. cerevisiae having PME activity could produce methanol during fermentation.
Methanol is produced during fermentation by the hydrolysis of naturally occurring pectin in the wort (Nakagawa et al.2000 ; Mendonca et al.2011 ). PME de-esterify pectin to low—methoxyl pectins resulting in the production of methanol (Chaiyasut et al.2013 ; Micheli 2001 ).
Jespersen ( 2003 ) reported the roles of S. cerevisiae in the traditional fermentation to include fermentation of carbohydrate to ethanol, production of aromatic and flavor compounds, stimulation of lactic acid bacteria and probiotic activities among others. Saccharomyces cerevisiae also inhibit the mycotoxin producing fungi and cause the degradation of poisonous cyanogenic glycosides and produces tissues degrading enzymes such as cellulose and pectinase.
The volume of ethanol produced during fermentation is dependent on the strains of yeast used. For instance, the total alcohol (ethanol and methanol) produced from orange juice fermentation was 3.19 % w/v with S. cerevisiae var. ellipsoideus and 6.80 % w/v with S.
- Carlsbergensis (Okunowo and Osuntoki 2007 ).
- During the production of sugarcane beverage called cachaca in Brazil, S.
- Cerevisiae produced no methanol while contaminating yeasts ( Pichia silvicola and P.
- Anomala ) produced 0.5 % methanol (Dato et al.2005 ).
- Stringini et al.
- 2009 ) studied yeast diversity during tapping and fermentation of oil palm wine from Cameroon and found S.
cerevisiae, Saccharomyces ludwigii, Schizosaccharomyces bailli, Candida parapsilosis, Pichia fermentans, Hanseniaspora uvarum and Candida fermentati in addition to lactic acid bacteria and acetic acid bacteria. Literature abounds on the microbiology of traditionally fermented beverages.
- Aramoko et al.
- 2012 ) isolated yeasts, mould and bacteria including Bacillus, Brevibacterium, Micrococcus and Escherichia coli,
- Rokusu and Nwisienyi ( 1980 ) isolated lactic acid bacteria ( Lactobacillus, Streptococcus and Leuconostoc ) and Acetic acid bacteria ( Acetobacter and Aerobacter ).
- Stringini et al.
( 2009 ) using molecular techniques reported the diversity of yeasts involved in palm wine fermentation including S. cerevisiae and other yeast such as Candida parapsilosis, C. fermentati and Pi c hia fermentans, Similarly, the microbiology of other traditionally fermented alcoholic beverages and foods have been well documented (Ogbadu et al.1997 ; Muyanja et al.2003 ; Namuguraya and Muyanja 2009 ; Quattara et al.2015 ; Koffi-Marcellin et al.2009 ; Ashmaig et al.2009 ; Eze et al.2011 ).
- Since traditional fermentation occur via spontaneous inoculation from the substrate and processing equipment (Ohimain et al.2012 ; Jespersen 2003 ), hence mixed cultures usually carry out the fermentation.
- Therefore, contaminating microbes including other yeasts, fungi and bacteria could result in the production of several other products including methanol.
And because methanol has a lower boiling point (65 °C) than ethanol (78 °C), it could be further concentrated in the beverage during distillation. Though, there are some disadvantages of mixed culture fermentation, the use of mixed culture in ethanol production will offer the advantage of production at low cost since a large range of substrates may be metabolized into ethanol.
Moreover, the high cost associated with operations of process plants with pure cultures could be drastically minimized when mixed cultures are used. As previously stated, mixed fermentation could result in the production of diverse products. Even pure culture fermentation can result in the production of diverse products depending on the operating conditions.
Hence, beverages produced via spontaneous fermentation by mixed culture could produce greater variety of products. Table 2 listed some volatile congeners produced in selected alcoholic beverages beside methanol. Some of these compounds are also very poisonous e.g.
What happens if you put too much yeast in moonshine 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.

Can you use too much yeast in moonshine?

Does any body have experimented that? Is there any other possible problems? If it does not create problems, I recommend this procedure.
It can ferment 4kg of sugar/18 L in less than 4 days! But I still waiting to see the final result after distillation. I have used 21 grams in a 5 gallon batch. Too much can cause stress to the yeast, and affect flavor, and give ya some wicked heartburn.
Will any yeast make 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.
Currently, you can purchase wine yeast for as little as $2.00. I haven’t priced bread yeast recently, but there can’t be that much difference in price. So if you value your time and effort at all go with the wine yeast. Don’t try making your wine with bread yeast. —– Ed Kraus is a 3rd generation home brewer/winemaker and has been an owner of E.C.

What is the alcohol tolerance of distillers yeast?
Alcohol Tolerance – Alcohol is toxic to all microorganisms, and this includes yeast. The alcohol tolerance of a given yeast strain determines how much alcohol it can produce before it reaches toxic levels and kills the yeast cells. Yeast has adapted to tolerate higher percentages of alcohol than most other microbes, and some strains tolerate alcohol better than others.
This is a result of the selection pressure imposed on the yeast used for different beverages. For example, wine yeasts can tolerate a high percentage (around 15% ABV). Beer yeasts are generally less tolerant, with some examples tolerating 8% ABV but some others up to 18% ABV. Baker’s yeast can be highly resistant to heat but cannot resist high alcohol concentrations (between 6-8 % ABV).
Distillers Yeast and turbo yeast can tolerate up to 18% and 21% ABV respectively. The higher the alcohol tolerance (and sugar tolerance) of the yeast, the more sugar you can add to your wash before fermentation in order to have a higher alcohol yield during distillation.
Can you make alcohol with any type of yeast?
Dry Active Yeast – Well, part of that packaging process also often includes drying out the yeast. There is no real difference between wet, live yeast and dry active yeast except that dry yeast has undergone a chemical process known as dehydration. In essence, it removes virtually all of the water from the yeast cells, making the yeast go dormant for a longer shelf life and easier shipping and handling.
Most yeast for wine, beer, and bread comes from the same basic strain, Saccharomyces cerevisiae, but there are hundreds of strains within that strain. So while you can absolutely use dry active yeast for wine, in fact there is dry active yeast made specifically for wine, you likely want to steer clear of dry active yeast made for bread, or baker’s yeast.
You can of course still use bread yeast as all yeast performs the same function – converting sugar to alcohol – but your wine will likely have a much lower alcohol content than normal. The yeast best suited for baking has a lower alcohol tolerance, so it will stop fermenting after alcohol levels reach about 8%.
What yeast do breweries use?
Beer Fundamentals – Beer has yeast in it? – Allagash Brewing Company Next to brewing, the most important part of a beer’s life cycle is fermentation. Like kombucha, wine, or your favorite bread, beer is fermented. Yes, every beer. From the lightest of light beers to the funkiest of wild and sour beer. Using grain and water, the brewer creates a sugary liquid called wort and then adds yeast to it.
Open fermentation in an oak foudre (basically a giant barrel). Yeast is a living organism—a unicellular fungi, to be more precise. The majority of beers use a yeast strain called Saccharomyces. This translates from Latin to “sugar fungus.” It’s apt, given that the yeast that goes into beer looooooves sugar.
- Within that genera, there are two specific species of Saccharomyces yeast that get the most use: lager yeast and ale yeast.
- Saccharomyces cerevisiae is a top-fermenting ale yeast, and most likely the yeast that brewers were inadvertently brewing with over 3,000 years ago.
- By top-fermenting, we mean that the yeast likes to rise up to the top of the beer as it eats (and creates alcohol, carbonation, etc.).
Ale yeast also tends to ferment best at hotter temperatures, with most preferring temperatures between 50°F and 70°F—with some saison yeasts getting up into the nineties at the peak of fermentation. Ale yeasts are responsible for a huge range of beer styles like,, ambers,,, IPAs, and so many more. An oak barrel filled with beer in the midst of fermentation. Saccharomyces pastorianus is a bottom-fermenting lager yeast. This type of yeast was originally found, and cultivated, by Bavarian brewers a little over 200 years ago. Bottom fermentation means it sits on the bottom of the tank as it ferments—this is also what happens during “lagering.” Lager yeast prefers much lower temperatures than an ale yeast: between 48°F and 58°F.
- Saccharomyces pastorianus is absolutely the most-used yeast when it comes to the raw amount of beer produced around the world.
- This yeast is responsible for beer styles like,, märzens, bocks, and more.
- A brief caveat, yeast is actually all around us.
- Similar to how bakers make sourdough bread, we can actually brew spontaneously fermented beer with and souring microbiota floating through the air.
You can read a whole lot more about the process of spontaneous fermentation on this page all about our How long does yeast take to ferment? Really, that depends on the beer. A beer like Allagash White normally takes around a week to ferment—and then another week to, which is a process of in-package refermentation that we won’t get into here.
What yeast for bourbon mash?
Which Type of Distillery Yeast Do Bourbon Distillers Use? – All bourbons use one yeast species known as Saccharomyces cerevisiae. However, this species exists in many different strains. Each strain is unique, and yeasts will produce various bourbon distillations.
- A distillery may use many different yeast strains and combinations for its bourbon.
- Many bourbon producers have their proprietary yeast strain, and each of those distilleries treats that information as a closely guarded secret.
- Everyone who tours these facilities must keep their hands visible, lest someone swipe a sample of the yeast strain.
Distilleries must keep their yeast strains in cryogenic freezers at negative 80 degrees Celsius, so storage is no small feat. These careful producers store their yeast strains in multiple locations, lest one suffer a power failure or burn down. Other bourbon distilleries purchase their yeasts from mass producers who supply yeast products to multiple companies.
What yeast is used in bourbon?
Pretty much every whiskey lover knows that without the addition of yeast to the cooked mash, all you would have is a pretty tasty, multi-grain porridge. After the starches in the corn, rye, and malted barley are converted to sugar by the enzyme amylase released from the malted barley, a multitude of single-celled fungi are added to the cooled mash.
- They proceed to gobble up those sugars, resulting in the production of alcohol and the release of carbon dioxide gas.
- You can see the bubbles of CO2 in the fermentation tanks.
- Your tour guide will issue a friendly warning not to lean too far over the tank for too long, not because the gas is toxic, because it is not.
But the cloud of CO2 has crowded out any oxygen above the tank. In short, you could pass out from lack of oxygen. (And wouldn’t you feel simply terrible about ruining a fermentation batch if you fell in?) But more is being produced by those busy little yeasties than alcohol and carbon dioxide.
- One of the chemical by-products of the activity is a class of aromatic compounds called esters.
- These are the molecules that lend fruits and flowers their various characteristic scents.
- For example, bananas smell like bananas because they contain the ester pentyl acetate.
- Oranges contain octyl acetate.
And apples get their odor from methyl butyrate. The essential oils of herbs and sweet spices also get their scent from esters. Rosmarinic acid is found in rosemary. Cinnamon oil’s is ethyl cinnamate. The reason bourbons vary in their detectable aromatics is that even though all are fermented by the same species of yeast, Saccharomyces cerevisiae, each distillery uses its own proprietary yeast strain.
Slight genetic variations within S. cerevisiae mean that different strains produce different esters. For example, a lot of people can detect the scent of banana on the nose of Old Forester expressions. Peach is a commonly identified aromatic on the nose of Elijah Craig. Famously, Four Roses Distillery has five different proprietary yeast strains, variously characterized as delicately fruity, lightly spicy, richly fruity, floral, and herbal.
In short, if you change the yeast strain you change the whiskey. Most of the major distilleries have laboratories where they employ microbiologists to propagate their yeast strains, which are stored in cryogenic freezers at minus 80 degrees Celsius. They are also usually stored at multiple sites in case of a prolonged power failure at one.
Since all forms of life have a pesky habit of evolving over generations, yeast, which like other microorganisms can produce multiple generations in a matter of hours, not decades, the distilleries’ scientists also monitor the yeast populations for mutations. Smaller distilleries simply buy their yeast from laboratories that specialize in developing and propagating different strains that produce different esters once they settle on the one with the aromatics they are looking for in their whiskeys.

Why is Jack Daniels not bourbon?
A bourbon must be distilled at no more than 160 proof, or 80% alcohol by volume. Jack is well under that. It comes over the still at 140 proof, or 70% alcohol.
Which yeast is used in fruit juice fermentation?
1.1.1. Sugars – Fruit juices contain high (8–20% wb) concentrations of sugars, typically sucrose, fructose, glucose, maltose, mannose, and maltotriose, Sugar concentration can be measured via density measurement (commonly reported as specific gravity or °Brix), or by identifying each sugar individually via high-performance liquid chromatography (HPLC).
The average Brix values for common fruit juices are listed by the United States Code of Federal Regulations (CFR) to provide a standard reference (21 CFR 101.30). Sugar is one of the major factors in overall flavor perception ; understanding the composition and concentration of sugars is part of identifying consumer preferences, as well as fermentability and economic advantages.
The ability to perceive sweetness is strongly impacted by sugar composition, as shown in Table 1, Sucrose is used as the reference standard for sugar sweetness, against which other sugars are measured, The quantity of each sugar also affects the perceived sweetness of the final product and should be taken into account when determining the impact of sugar on taste.
- Throughout fermentation, yeast obtain energy by converting sugar into ethanol and carbon dioxide.
- However, some sugars are not fermentable by traditional beer yeast.
- The most-used yeast species in brewing fermentation are Saccharomyces spp., which can utilize sucrose, fructose, glucose, maltose, and maltotriose, in this preferential order, with some overlap,
Sugars and similar compounds unfermentable by Saccharomyces spp. include dextrins (hydrolyzed starch or maltodextrins), sugar alcohols, lactose, and beta-glucans, Unfermentable components are often included in fermented products to either increase the perceived sweetness of the final product (e.g., lactose) or to increase the thickness and body and modify the mouthfeel (maltodextrin),
What is the best yeast for a fruit mead?
Interested in making your own mead at home? Since ancient times, mead has been made using two ingredients – honey and water. However, it is a fermented drink meaning that yeast is also required. Different yeast strains should be considered depending on your desired flavor or sweetness.
- The best yeast for mead is champagne or wine yeast, such as D-47.
- D-47 yeast produces a well-rounded mead, liked by many.
- Various types of yeast can be used to make mead, chosen based on the flavor profile, alcohol percentage, and carbonation you want.
- Baking yeast cannot be used for mead.
- While the main ingredients required for making mead are honey and water, yeast is used to quicken the fermentation process.
Selecting the correct yeast for the flavor profile and carbonation you want in your mead is essential.
What is the best yeast for fruit cider?
Adding Yeast – The most commonly used yeast is a champagne yeast. Being a very aggressive yeast, it ferments quickly to a very clean, dry flavor that suits the apple character very well. This yeast is cheap, easy to use, and makes a delicious, consistent beverage.
We always make sure to do a few carboys with the champagne yeast, so we know that no matter what else happens, we will have it as our benchmark to compare all other ciders against. In recent years, as cider has exploded in popularity, there have been great advances in the yeasts available to the home cider-maker.
We stock several cider-specific yeasts; Safcider by Fermentis and Mangrove Jack’s Cider Yeast are favorites. We are also enamored with the cider produced by the delicate CY-17 yeast; although it is slower and less vigorous than other cider yeasts, it leaves a lovely aroma and fruity taste in a cider that ferments under optimal conditions.
Another excellent yeast to use is the SN-9 wine yeast from Vintner’s Harvest. Although still dry, as indeed any home-fermented cider will be, it has a flavor that is a little sweeter and softer than the champagne yeast, and it is especially lovely when honey is used as the bottling sugar. There are others; Clos De Bois, for an aromatic sip, or CL-23, for a clean, crisp cider.
Any beer yeast will also create apple cider, however, some are much better than others. One of our favorites is the Safale US-05, which is a yeast commonly used to make pale ales and IPAs. It has a crisp, clean flavor. One of the best ciders I’ve ever tasted was made with a Belgian ale yeast; the typically fruity character of that yeast suited the apple perfectly, and left some sugars unfermented at the end, for a slightly sweeter cider.
It is with beer yeasts though that we have also had some of our least successful adventures. One year, in an effort to leave some sugars unfermented, we made something like 20 gallons of cider with S-04, an English ale yeast that does produce delicious beer. An English ale is typically a little sweeter, we reasoned, so perhaps this would lead to a sweeter cider? Alas, no.
It led to 20 gallons of dry cider, that had a beery, English ale aftertaste. Lesson learned. All in search of the perfect cider.
What kind of yeast do you use for fruit beer?
Yeast: – Pick a clean fermenting, high attenuating yeast. Using yeast with a complex profile is possible, but the yeast flavors and fruit flavors may not work well together. (Safale US-05 and Wyeast 1056 American Ale could both work.)
