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 earliest beer was just slightly fermented barley juice with a little wine flavor. According to the difference of temperature and yeast species (people didn't know what it was at that time), it was divided into Lager and Al. The difference between them lies in the different fermentation positions. Lager ferments at low temperature under the fermentation barrel, while Al ferments in the warm environment above. For example, when men see women, most of them will think in the lower half, so lager is more common than Al.
All beer in China, Heineken, Carlsberg, Budweiser and many German beers belong to this category, which is simple and has no moral integrity. But this is not the case. Lager is actually more difficult to ferment in small batches than Al, because the temperature requirement is lower, but later industrial production solved this problem. Lager beer has mild fermentation, pure body and light taste, which is the fundamental reason for its popularity.
Compared with Lager, Al is more literary, which is found in Benelux, Nordic countries and England. This wine has a high-end atmosphere, so most beer techniques refer to these.
In the Middle Ages, the water quality in northern Europe was very poor, but people didn't like drinking boiled water, so a group of monks in Belgium began to brew beer with boiled water, which could be used as water and tasted good. Everyone thinks beer is a drink, so there is no ban on drinking beer. Later, it became more and more popular, so Belgium became a school of its own, Abbey style (abbey
Beer), we are talking about blond hair (Ai Jin), double (double), triple (triple), brown (brown wormwood) and even quadruple (quadruple).
Results The water quality in Britain and Ireland is more exaggerated and super hard (calcium sulfate). In order to cover up the taste, they can only use a lot of roasted malt to lower the PH value, and use burnt malt to cover up the taste of water, so there is Porter. Later, everyone thought that the taste of coke was not cool enough, so it would be nice to have some paste, so there was dark beer, which was later upgraded to imperial use.
Stout), these wines are generally characterized by high alcohol content.
Later, the British colonized India, and the beer easily deteriorated after being shipped by sea. They found that adding hops can ensure the quality, so a new variety appeared: Indian pale ale, the legendary IPA (India
Pale ale (Indian lavender), the more people drink, the more popular it is, but this wine has nothing to do with India.
