In the context of alcohol production, briefly outline the process of fermentation
Alcohol is produced by a process called fermentation, which was discovered thousands of years ago. Fermentation occurs when single-cell microorganisms called yeast metabolize the sugars found in fruits and grains, ultimately producing ethanol and carbon dioxide. Once the alcohol content of a beverage reaches a certain point, fermentation stops naturally. Depending on the strain of yeast used, fermentation usually stops naturally in a barley-based beer when alcohol by volume (ABV) reaches four to eight percent and in a grape-based wine when ABV reaches 11 to 14 percent.
