The transformation of various grains, fruits, and vegetables into ethanol or alcohol can only be achieved through fermentation and complete fermentation of yeast is crucial for alcohol production. Active yeast starts the metabolism process within the mixture of water and other ingredients that result in the conversion of sugars into alcohol.
Yeast is classified as micro-organisms from the fungi family. These yeasts are available in a wide range and they contribute greatly in the creation of various alcohols ranging from mild ones such as beer to medium ones such as wine to stronger ones such as vodka. Thus, brewer’s yeast such as saccharomyces cerevisiae yeast or ale yeast as it is also known is used to ferment beer. Similarly, yeast saccharomyces is used to ferment lager beer. On the other hand wine is fermented using wine yeast while strong distillers yeast such as vodka yeast is used to produce strong spirits such as vodka.
Even before the addition of yeast into the mixture, other processes need to be executed to make the mixture ready for fermentation. This mixture is usually a combination of water along with wheat or grapes or corn or rice or sugar or barley or any other source rich in starch, based on the alcohol or spirit that needs to be produced and also based on the region where it is to be produced. There is usually a primary starch source used while a secondary starch source is also added in some types of alcohol production.
The initial processes of milling, mashing, boiling and cooling results in the release of certain enzymes such as amylase that help in converting starches into sugars including glucose, sucrose, fructose, etc, depending on the constitution of the mixture. The mixture has to be cooled to temperatures below 27 degrees Celsius since regular yeast cannot ferment above these temperatures. However, improved yeast forms such as turbo yeast performs well even in a higher range of yeast temperature as well as offers better alcohol tolerance. Such yeast can easily survive in temperatures of up to 38 degrees Celsius while still providing stronger alcohols.
The fermentation of yeast results in each molecule of glucose getting transformed into two molecules of ethanol and two molecules of carbon dioxide. This carbon dioxide is usually also used to carbonate the final alcoholic beverage. The sugar fermentation process also determines the strength of the ethanol alcohol while also playing a large part in determining the color and taste of the final product. Some alcohol drinks also require another round of alcohol fermentation so as to produce a stronger drink or to increase the clarity of the drink.
There are also various methods in the fermentation yeast process such as warm fermentation, cold fermentation, etc. Various breweries and distilleries use different temperature settings during the fermentation process although better yeast alternatives in the form of turbo yeast can help producers increase their alcohol yield as this instant yeast can ferment in higher temperatures as well as produce top quality alcohols and spirits even from weak mixtures.
Alcohol or ethanol production requires several processes including fermentation so as to convert all starch present in the ingredients into sugar before it is ultimately converted into alcohol. This process requires producers to maintain ideal temperature settings as well as ensure constant monitoring over the strength of alcohol that is to be produced. Complete fermentation of yeast is crucial for alcohol production so as to get rewarded with alcoholic drinks that have that perfect color, character, clarity, and strength.
