I guess something like a trad strong IPA (8%+) might last OK? But there the hops is as much a preservative as anything and will mellow as the beer matures, as opposed to to a modern fresh hop bomb style that will go off.
But +1 for the suck it and see approach; worst case is just that it'll be flat and dull and need to be poured away, but you might get something rather interesting.
I was given some bottle conditioned beer for my 18th. 10 years later, will it still be fit for human consumption?
