The answer, as with most things in life, is: it depends. Beer typically lasts for six to nine months past the expiration date on its label. If the beer is refrigerated, it can last up to two years beyond the expiration date.

Can old refrigerated beer make you sick?

Drinking beer past the expiration date is not ideal, but in the event that you drink a “rotten beer”, just know that drinking a bad beer probably won't make you sick and it won't kill you. At the most, you can expect a bit of a stomach ache and a slight feeling of disappointment and disgust.

Can you drink refrigerated expired beer?

The simple answer is yes, the beer is still good insofar as it is safe to drink. Since most beer is either pasteurized or filtered to eliminate bacteria, it's extremely resistant to spoiling. How the beer will taste is another matter.
