What natural process is used to produce beverage alcohol?

The process of fermentation is a natural biological reaction where yeast or bacteria convert sugars into alcohol and carbon dioxide. This occurs when yeast metabolizes the sugars present in various sources such as grapes for wine, grains for beer, or fruits for spirits. During fermentation, the yeast consumes the sugars and produces ethanol as a byproduct, which is the alcohol found in beverages.

This process is foundational to the production of many alcoholic beverages and is crucial because it not only creates the alcohol content but also contributes to the flavor profile and complexity of the drink. For instance, the type of yeast used, the sugars fermented, and the fermentation conditions can all influence the taste and characteristics of the final product.

While distillation is another process that can increase the alcohol concentration of a beverage produced through fermentation, it is not the process that directly creates alcohol from sugars; rather, it is a method used afterward to purify and concentrate the alcohol. Oxidation refers to a chemical reaction that can occur after fermentation and may affect the flavor of wines and beers but does not produce alcohol. Concentration is a general term that does not specifically relate to the production of alcohol in this context.
