Beer:
Beer is an alcoholic beverage made from malt, barley malt and hops by liquid gelatinization and saccharification and then liquid fermentation. Beer has low alcohol content, including carbon dioxide, various amino acids, vitamins, low molecular sugar, inorganic salts and various enzymes. Among them, low molecular weight sugars and amino acids are easily digested and absorbed, which produces a lot of heat energy in the body, so beer is often called "liquid bread".
