My answer to your question is as follows, please refer to: drinking too much beer will not kill you. Beer is like a drink with low alcohol content. Let me introduce you to its knowledge. You can see the natural white color: what is beer? It is a nutritious beer with barley malt and water as the main raw materials, hops as the spice and yeast, which is rich in carbon dioxide, with many bubbles, low alcohol content. It has the effect of relieving summer heat and appetizing. Health care and other functions. The healthy value of beer is called liquid bread. The proportion of sugar and protein in beer is most in line with the nutritional balance of human body, and the protein contained in beer is almost completely absorbed and utilized by human body. The calories per liter of beer can reach 430 calories, which is equivalent to 6-7 eggs, 0.75 liter of milk or 50 grams of cream. Beer contains 65,438+07 kinds of amino acids, vitamins and mineral salts. 1972 is recommended as a nutritious food by the World Nutrition Association, and is known as "liquid bread". The traditional technological process of beer brewing is: firstly, the germinated barley is crushed, then 65.5% hot water is added and stirred into paste, and then wort is obtained by filtration. Boil the wort, add "hops" at the same time, then cool and add yeast. The fermented liquid turned into beer. Beer can be divided into upper fermented beer and lower fermented beer according to fermentation methods. China and most countries use the following fermentation methods to produce beer. Upper fermentation beer: the fermentation temperature is high (15-20℃), and it can be started quickly. Most yeasts float on the liquid surface in the later stage of fermentation, and the fermentation period is 4-6 days. Short production cycle, rapid equipment turnover and unique beer flavor. However, the shelf life is short. Famous top fermented beers include Albee, Dark Beer, Porter Dark Beer, etc. Lower fermented beer: the main fermentation temperature is low (not more than 13℃) and the fermentation process is slow (the fermentation period is 5- 10 day). Due to the use of bottom fermentation yeast, most of the yeast is precipitated at the bottom of the container in the later stage of main fermentation. The post-fermentation period of bottom fermentation is longer. Long shelf life. Famous fermented beers include Bilsen light beer, Dortmund light beer and Munich dark beer. According to color, there are three kinds of light beer: golden color, light and refreshing taste and outstanding hops flavor. Strong color beer: reddish brown in color, mellow in taste, light in dry taste and strong in malt flavor. Dark beer: dark red and brown are dark brown, with high concentration of original wort and mellow taste. The taste of malt is outstanding. The difference between draft beer and ordinary cooked beer is that a can of beer liquid can be made into both cooked beer and draft beer. The technical difference is that the cooked beer is sterilized by heating, while the draft beer is filtered by microporous membrane, which keeps the original and freshest taste of beer liquid, which is why the draft beer is fresher and more delicious than the ordinary cooked beer. The difference between draft beer and draft beer is that draft beer adopts aseptic membrane filtration technology. Excluding yeast and miscellaneous bacteria, the shelf life of draft beer can reach 180 days. Although draft beer is sterilized at high temperature, it uses diatomite filter, which can only filter out yeast and miscellaneous bacteria, so the shelf life is generally 37 days. At first glance, the color should be light yellow, the transparency should be clear and transparent, and the foam should be white and delicate. Pour it into a cup and hang it for a long time. Second smell: There should be obvious fragrance of draught beer flowers: the taste is pure, refreshing, mellow, without any miscellaneous taste. Degree of beer: the degree of beer and the degree of liquor are two different things. The degree of liquor is its alcohol content, while the degree of beer actually refers to the concentration of wort. For example, 1 1 degree beer is brewed with wort with sugar content of 1 1 degree, and the alcohol content of beer is mostly between 3.5% and 4%. Beer should be chilled before drinking, and the best drinking temperature is about 8- 10 degrees Celsius. The solubility of carbon dioxide in beer varies with temperature. Foam increases, but soon disappears, the temperature is low, and carbon dioxide escapes less. Foam will also be reduced, so the drinking temperature of beer is very important. Appropriate temperature can make the various components of beer coordinated and balanced, giving people the best taste. When you pour beer, pour it on the table. When pouring, the bottle mouth should not be close to the edge of the cup, and it can be poured along the wall of the cup. If there is too much foam, pour it twice. Liquor accounts for 3/4. Foam accounts for 1/4. Beer should not be chewed slowly, otherwise the temperature in the mouth will aggravate the bitterness. Therefore, it is advisable to gulp down beer and let the wine fully contact with the mouth, so as to taste the unique taste of beer. Don't pour a new bottle of beer into the leftover beer glass, it will spoil the taste of the new beer. The best way is to drink it dry before pouring it.
