I saw the String cheese post so I thought I'd share my own "slightly beyond best before date" consumable. I used to have two of them that I had found in my attic under some insulation, but the other one froze in my garage and broke open. (No, it did NOT smell pleasant. I'm pretty sure whatever vile liquid is in that thing does not resemble beer in any way, shape, or form.)
It's perched on a flashlight to try and show the sediment that's built up on the bottom of the bottle.

You know, there are some kinds of beer that are intended to be aged. I have one bottle of a Russian Imperial Stout that I brewd 7 years ago. But the beer you referred in you post is definitely not the aging kind. In fact, it's supposed to be consumed as fresh as possible. A sample with that age have definitely gone bad.
I have a suspicion that this stuff was probably pretty bad the day it was bottled.
Hahaahahahhahah indeed!!
