Yeast cells are the active ingredient to convert organic material into alcohol. Ethanol fermentation (production of alcohol) takes place when oxygen is not present in yeast cells and they still need to produce energy. The yeast cells well take monosaccarides such as glucose or fructose and break them down to form energy the by products are carbon dioxide and alcohol.
