In the process of producing alcoholic beverages, different substrates can be used like grape juice, sugar cane, cereals, etc. Yeast (Saccharomyces cerevisiae) transforms or ferments the sugars present in them into alcohol and carbon dioxide anaerobically. This process is called alcoholic or ethanol fermentation.

Depending on the type of the raw material used for fermentation of alcoholic beverages and the type of processing i.e with or without distillation, various types of alcoholic drinks are obtained:
Wine and beer are produced without distillation
Whisky, brandy and rum are produced by distillation of the fermented broth.
