The development of world beer industry is closely related to the origin of grain. It has been more than 8,000 years since people made alcoholic beverages from grains. The oldest known wine literature is the method of making sacrificial beer carved by Babylonians with clay tablets around 6000 BC.
In 4000 BC, there were 16 kinds of beer made of barley, wheat and honey in Mesopotamia. Bitter agents have been used since 3000 BC. In the 8th century BC/KLOC-0, there were detailed records about beer in the code issued by King Hammurabi of Babylon (BC 1750). Around 1300 BC, Egyptian beer developed highly as an excellent industry under state management.
The hieroglyphics on the Rosetta stone discovered by Napoleon's Egyptian Expeditionary Force in Egypt show that beer feasts were very popular in this area around BC 196. Although bittering agents have been used for a long time, hops were first used as bittering agents in 768 AD. Beer brewing technology was introduced into western Europe from Egypt through Greece. The ancient Roman politician Pliny (62 ~ 1 13) mentioned the methods of making beer, including the use of hops. Before the Middle Ages, beer was mostly brewed by women at home.
By the Middle Ages, beer brewing had changed from family production to workshop production in monasteries and villages, which became an important part of monasteries' life. The main food in the monastery is bread and beer. Medieval monasteries improved the brewing technology of beer, and the trade relationship of beer was also established and controlled by priests. In the Middle Ages, beer could be used to pay tithes to churches, trade and pay taxes to governments in Europe.
In medieval Germany, beer brewing owners formed a powerful trade association. German beer using hops as bittering agent is also exported abroad, and cities such as Bremen and Hamburg have prospered. 17 ~ 18 century, German beer prevailed, which once depressed wine. /kloc-At the beginning of the 9th century, British beer production was industrialized on a large scale, with an annual output of 20Ml. /kloc-In the middle of the 0/9th century, the following fermentation methods began to appear in Bavaria, Germany, and the brewed beer gradually became popular throughout the country because of its good flavor. At present, in Germany, 92% of beer is produced by the following fermentation methods.
/kloc-in the 0/9th century, Germany promulgated laws to strictly regulate the raw materials of stele wine in order to maintain the purity of beer. Moreover, due to the subsequent fermentation method and regular yeast pure culture, the quality of beer has been improved, which has become the basis of modern Munich beer's reputation. In the New World of America, Protestants from the Netherlands and Britain introduced beer technology in the early17th century, and the first brewery was established in Massachusetts in 1637.
Soon, beer developed rapidly as a modern industry, making the United States a beer producer that surpassed Germany. /kloc-in the 0/9th century, winemakers elaborated winemaking technology one after another. 1857, L. Pasteur established the theory of biological fermentation; 1845, C. J. Bahrain expounded the theory of fermentation degree; 188 1 year, E hansen invented the pure culture method of yeast, which made the science of beer brewing advance by leaps and bounds, from mystery and empiricism to science. The application of steam engine and the invention of 1874 Linde refrigerator made the industrialized production of beer a reality. At present, the annual output of beer ranks first among all kinds of wines in the world, which has exceeded 100000Ml. 1986 10 1588.7Ml beer was produced all over the world.
