Ethyl Alcohol Fermentation is used by wineries and brewing companies to produce commercially consumable alcholo beverages. Grapes are fermentated for wines, and wheat/barley is fermented for producing beers.

Lactic acid fermentation using anaerobic bacteria results in the production of foods like yogurt or sauerkraut. Sugars are converted into ATP for the bacteria to live and they produce lactic acid as a waste product. Yogurt is produced this way, and this acid gives yogurt its sour flavor. Sauerkraut gets its flavor from this acidity as well as simple alcohols and other hydrocarbons that are formed after fermentation occurs. Yeast will anaerobically convert carbohydrates to carbon dioxide and alcohol. This is the alcohol found in such beverages as beer and wine. Ethanol is the alcohol produced by fermentation. The yeast also produce carbon dioxide gas as a bi-product of this reaction. The baking industry relies on yeast to allow dough to rise. Yeasts convert carbohydrates in the dough into alcohol and carbon dioxide. As this gas escapes, the bread rises and the alcohol evaporates during baking.
