The concentration of wort is 8 ~12, and the alcohol content is about 2.5%~4%, which is the main variety of beer production in China. The alcohol content of light and cool beer is about 2.5%, pure beer is about 3%, and dry beer is about 4%. The concentration of wort is14 ~ 20, and the alcohol content is 5%~ 10%. Most German beer and craft beer belong to this category.
It should be noted that the degree of beer does not represent its alcohol content, but refers to the concentration of wort. At the same time, different brands and different kinds of beer have different alcohol contents.
Matters needing attention in buying beer:
1, when buying bottled beer, you should carefully check whether there is a "B" mark at the bottom 2CM of the bottle body, and try not to buy beer bottles with serious surface wear.
2, in the purchase process and drinking, pay special attention to self-prevention, to avoid violent shaking and collision.
3. The storage temperature of beer is 5℃~25℃. Attention should be paid to avoid strong light and high temperature, and beer should not be directly put into the freezer for rapid cooling. Beer should not be trapped in the refrigerator during cold storage, and the temperature should not be too low.
4. When drinking beer, never put unopened bottled beer on the dining table or near people, so as to avoid the explosion of beer bottles caused by man-made kicking. When eating and drinking beer in a restaurant, it is best to ask the waiter to open the bottle.
