Is the beer good after a year?

* What kind of beer is it? Different styles of beer age differently. For example, a stout or a barleywine might improve with age, while a light lager would probably not.

* How was the beer stored? Proper storage is crucial for aging beer. It should be kept in a cool, dark place, ideally at a consistent temperature.

* What is the "best before" date on the bottle/can? This is a good indication of how long the beer is expected to be good.

Once you provide me with more information, I can give you a better answer!
