If the package is intact, it does not exceed the shelf life, but I think it is better not to drink if it is not too much. Here are some references for you to judge according to your own situation. ① The storage environment of beer should be between 0 ~ 15℃, preferably around 10℃, and the bottled mature beer should be stored between 5 ~ 25℃; If the temperature is too high, the beer foam will not last; When the temperature is too low, the foam decreases and the bitterness increases; Below 0℃, the appearance is cloudy and the taste is not good. Therefore, beer should not be stored in the refrigerator in any season.

(2) Beer is sensitive to light, so don't expose it to the sun or shake it violently to prevent the yeast in beer from being heated, turbid and precipitated.

(3) Oil pollution is the enemy of beer. Beer should be kept clean and not contaminated with oil pollution, because oil pollution will make hops disappear too quickly.

④ Bottled draft beer should not exceed 5 days, bottled draft beer should not exceed 65,438+05 days, and cooked beer should not exceed 45 days.

⑤ The leftover beer should be sealed to prevent the disappearance of carbon dioxide and affect the alcohol composition and concentration in the beer.
