How long will it take after the beer has been opened?
Beer has a shelf life, that is to say you put him out to the outside from the cold box, even if it does not open the beer is sour. The best storage temperature of beer is 0--5 degrees Celsius, and the main thing to drink beer is to drink his refreshing strength, so it is better not to drink it directly after opening. But, if you say something bad, it doesn't happen. Beer is a fermented product. It doesn't have bad troubles, but it tastes good, so don't worry about bad or bad quality.
Beer should be instant drink, open beer too long, carbon dioxide gas ran away, drink it makes people feel bitter and tasteless, tasteless, but also easy to microbial cause spoilage. The most important thing is that the taste will become bad.
