1, the brewing method of beer is very simple, which can be roughly divided into malting, saccharification, fermentation and canning. Firstly, malt is crushed, rice and other auxiliary materials and warm water are added, stirred, heated to a certain temperature, and impurities are filtered to obtain clear wort. Put these liquids into a boiling pot, add hops, boil, cool, and add beer yeast. At the beginning of fermentation, yeast will decompose the sugar in maltose into alcohol and carbonic acid gas. After a week of low-temperature fermentation, it will become tender beer.

2. There is a certain relationship between the origin of beer and the origin of grain. For thousands of years, people have been making drinks from grains. The oldest known wine literature is the method of making sacrificial beer carved by Babylonians with clay tablets around 6000 BC. Around 1300 BC, Egyptian beer, as an excellent industry under state management, has been highly developed. The hieroglyphics on the Rosetta stone discovered by Napoleon's Egyptian Expeditionary Force in Egypt show that beer feasts have been popular since BC 196. /kloc-At the end of 0/9th century, beer entered China, but at that time, the beer industry developed slowly, was not widely distributed, and the output was not large.
