Ethanol contained in alcoholic beverages is produced by means of fermentation induced by yeast. Liquors are distilled from grains, fruits, vegetables, or sugar that have already gone through alcoholic fermentation. Alcohol products: Natural sugars present in grapes;
Kilju (Finnish pronunciation:) is the Finnish word for a mead-like homemade alcoholic beverage made from a source of carbohydrates (such as cane sugar or honey), yeast, and water, making it both affordable and cheap to produce. The ABV depends on the yeast that was used, and since it does not contain a sweet reserve it is completely dry.

People choose to brew their own beer for a variety of reasons. Many homebrew to avoid a higher cost of buying commercially equivalent beverages. [10] Brewing domestically also affords one the freedom to adjust recipes according to one's own preference, create beverages that are unavailable on the open market or beverages that may contain fewer calories, or less or more alcohol.
The more popular methods for production of ethanol and cellulosic ethanol use enzymes that must be isolated first to be added to the biomass and thus convert the starch or cellulose into simple sugars, followed then by yeast fermentation into ethanol. This process does not need the addition of such enzymes as these microorganisms make their own ...
Fermentation is the anaerobic metabolic process that converts sugar into acids, gases, or alcohols in oxygen starved environments. Yeast and many other microbes commonly use fermentation to carry out anaerobic respiration necessary for survival. Even the human body carries out fermentation processes from time to time, such as during long ...
