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". 10 12 BX beer can generate 3344kJ of heat, which is equivalent to the heat generated by 3 ~ 5 eggs or 2 10g bread. A light manual worker who can drink 1L beer a day can get one-third of the calories he needs.
Name source:
The name "beer" is translated from a foreign homonym. Take the word "beer" as an example, it didn't exist in China's dictionary in the past.
Later, some people called beer "Bier" according to foreign names such as Germany and the Netherlands. Britain calls it "beer"; France calls it "Biere"; Italy is called "Birre"; Romania calls it "Beria" and so on. These foreign languages all contain the sound of "beer", so translating the word "beer" into Chinese created this foreign language, and because of its certain alcohol content, the word "beer" was used in translation and has been used ever since. Because barley malt is the main raw material, the Japanese also call beer "ale".
