How long will beer last in a can?

I have a small collection of unopened 'collector' beer that intend to keep for a very long time. How long will it last inside the can before the can will begin to detoriate and leek beer? Obviously were talking about a standard tin can here filled with beer.|||Depends on the alcohol level. Most beers above 8% mellow and improve with age. (the flavors blend) 3.25-6% are meant to be drank fresh.





Personally I would not drink a can of " standard 5% " beer that was older then 2 years and generally 1 year is the max. It will not leak for at least 20 years and likely 75.|||Most mass-produced beer is intended to be consumed fresh. There is usually a freshness date somewhere on the can.

I hope the beer lasts longer than your brain cells. LEAK is the word. A leek is a vegetable belonging to the onion family.|||Drink it now! However, there is a date on it! Other than that, 6 months if it's kept in a cool place .....but I've drunk a can after 6 years ....it was 'orrid!|||I never drink beer in cans. The beer is all right but the air fare to Cannes is too expensive.|||Call the 800 number and ask there reseach depts. If you decide to pour it out it makes good lawn food. *mamatx
