Alcoholic drinks such as wine, beer, whiskey, rum, vodka, and many others need yeast to ferment the particular mixture of water combined with unfermented grains, vegetables or fruits, based on the beverage that needs to be developed. While milder alcohols such as beer and lager might be fermented by using brewing yeast such as yeast saccharomyces or saccharomyces cerevisiae yeast, more robust alcohols as well as spirits require robust yeast which can make it through inside higher proof levels.
