Beer is one of the oldest alcoholic beverages and the third largest beverage in the world after water and tea. Beer was introduced to China in the early 20th century, and it is an imported wine. Beer is translated into Chinese "beer" according to English beer, which is called "beer" and is still in use today.

Beer is a low-alcohol wine full of carbon dioxide, which is made from malt, hops and water by yeast fermentation. It is called "liquid bread" and is a low-concentration alcoholic beverage. Beer has the least ethanol content, so drinking beer is not only not easy to poison people and harm the body, but also beneficial to the body. At present, most beers in the world have added auxiliary materials.

Some countries stipulate that the total amount of auxiliary raw materials should not exceed 50% of malt consumption. In Germany, except for exporting beer, all beer sold in Germany does not use auxiliary raw materials. In 2009, the beer production in Asia was about 58.67 million kiloliters, surpassing Europe for the first time and becoming the largest beer production place in the world.

Pottery found in Mijiaya archaeological site in northern China contains beer ingredients about 5,000 years ago. Archaeologists found yellow residues in pottery funnels and wide-mouthed pottery pots, indicating that many ingredients fermented together include millet, barley, coix seed and tuber crops.
