Edible alcohol
Edible Alcohol, also known as fermented distilled spirits, is mainly made from potatoes, grains, and sugars as raw materials through cooking, saccharification, fermentation and other treatments. It is used in the food industry to produce hydrous alcohol. The four parts, aroma, taste and body, refer to the content of the four main impurities in distilled wine, aldehydes, acids, esters and alcohols. Different tastes and gases will make the flavor of distilled wine different.
