Detailed explanation-1: -Under anaerobic conditions, yeasts gain their energy from a similar process referred to as alcoholic fermentation.

Detailed explanation-2: -Alcoholic fermentation is the basis for the manufacturing of alcoholic beverages such as wine and beer. Control of fermentation is generally considered as a prerequisite to determine the quality of the final product.

Detailed explanation-3: -Alcohol fermentation has two steps: glycolysis and NADH regeneration. During glycolysis, one glucose molecule is converted to two pyruvate molecules, producing two net ATP and two NADH.

Detailed explanation-4: -Firstly, and after the grapes and/or must have been placed in vats, a first fermentation takes place that is common to all wines. In this fermentation, the sugars of the grape start to turn into ethanol in an oxygen and temperature-controlled environment. This fermentation is known as “alcoholic fermentation”.

Detailed explanation-5: -A Guide to Beer Fermentation. Fermentation is a process whereby yeast converts glucose in the wort to ethyl alcohol and carbon dioxide gas (CO2) to give beer its alcohol content and carbonation. The fermentation process starts when cooled wort is transferred to a fermenting vessel and yeast is added.
