2. Beer is the oldest alcoholic beverage of mankind 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 rich in carbon dioxide, which is made of barley malt, hops and water by yeast fermentation.
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 (German: Bier), 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.
