What's the shelf life of beer?

It probably won't be tasty (beer does not get better with age-- one of the advantages of homebrewing), but as long as it doesn't smell bad or excessively fizzy, it should be okay.

You've had beer in the fridge for several years!?!?! ...the tragedy is overwhelming. My recommendation is to drop them off with some college students, and just don't tell them it's that old. they won't care, and i doubt it'll kill them. ;-) that way it doesn't have to go to waste! Yay environment!

Apologies to all beer drinkers (that would be most of the population, I guess). But in spite of Evan's heartfelt plea, I have decided to use my aged beer to catch slugs. That is also good for the environment, or at least, my garden.

It depends on the type of beer. The darker the beer, the longer it will last; a stout will last for years.

Well my local pub gardener dug up a bottle in the beer garden rusty cap and all, and guess what it tasted beautiful

I’d use it to wash my hair
