So I have this problem where i buy tons of booze, even though I rarely drink it. This means I have a giant collection of opened bottles that are basically full. I have been keeping them in my fridge. However, I got to thinking tonight and am wondering if they're OK to consume.
The scientist in me tells me it should be OK because the alcohol content would prevent any life from existing in there (i.e., bacteria). However, the nerd in me got me doing a bit of gooling, and it seems that opened booze only lasts for some months after opening - presumably as a result of oxidation etc. resulting from contact with oxygen? I can see this *possibly* degrading the flavor, but I can't see it making it unsafe.
What do you think - would you drink old, opened booze? How old of stuff would you drink?
