Beer is a common beverage, which is mostly fermented from malt and barley malt. It contains a lot of carbohydrates, alcohol and other substances. Alcohol is a carcinogen, so drinking alcohol is not recommended in daily life.

If it is found that the beer you drink exceeds the shelf life, there may be turbid liquid and bacteria, which may change the original food properties of beer. If bad beer enters the human body, it will have a certain impact on human health, so it is not recommended to drink beer after its expiration.

Preservation of beer

1. Keep it fresh in the refrigerator.

The most common and best way to keep fresh is to keep fresh in the refrigerator. In daily life, drinks, vegetables and fruits are often put in the refrigerator to delay deterioration. Of course, this method can also be used in beer, and frozen beer tastes fresher and more refreshing. When storing beer in the refrigerator, you should also be careful not to put the beer in the freezing layer to avoid the beer can being frozen and cracked by the frozen beer. You should put the beer on the fresh-keeping layer, the cold temperature is just right and the taste is right.

2. Stay away from light and high temperature.

Perhaps careful people have noticed that most beer bottles are dark, because carbonic acid contained in beer will produce carbon dioxide in sunlight and high temperature environment, and long-term illumination will accelerate the deterioration of beer, while using dark bottles can block the light and better improve the preservation quality of beer. Therefore, if there is no refrigerator, beer should be stored in a dark and cool place.
