Where did beer originate? How many years?

1. Beer originated in Germany. In 786 A.D., a German monk tried to use hops in beer production, which improved the quality of beer. But it was not until the 15th century that hops were formally identified as the spice of beer. 1850-1880, France's Pasteur established the physiological view of microorganisms and created the famous pasteurization method: in 1878, Lorentz Enzger developed a filtration device, which removes turbid substances from beer; in 1881, the Danish Emile Kristian Hansen discovered a large number of beer products. In 1881, the Dane Emil Christian Hansen discovered a large number of fermenting bacteria strains, which he successfully cultivated soon afterward: subsequently, freezers also began to be used in the beer industry. These new technologies enabled beer brewing to move into a new phase of industrialized scale, and modern beer was basically finalized. It is one of the oldest alcoholic beverages of mankind, and is the third most consumed beverage in the world after water and tea. Beer was introduced to China at the beginning of the twentieth century, and is a foreign type of alcohol. Beer is based on the English Beer translated into Chinese "beer", called it "beer", used today.

2, beer to barley malt, hops, water as the main raw material, by the yeast fermentation brewed from the carbon dioxide-filled low alcohol wine, known as "liquid bread", is a low concentration of alcoholic beverages. Beer has the lowest ethanol content, so drinking beer is not only not easy to get drunk and hurt people, but a small amount of drinking on the contrary, it is good for health. Now most of the international beer are added auxiliary raw materials.

3, some countries stipulate that the amount of auxiliary raw materials totaling no more than 50% of the amount of malt. In Germany, except for the export of beer, Germany's domestic sales of beer do not use the auxiliary raw materials. In 2009, Asia produced about 58.67 million kiloliters of beer, surpassing Europe for the first time as the world's largest beer producer.
