Dubbels and Tripels etc are examples of what I said - bottle conditioned. And sure, other beer spoils, but it doesn’t age in a bottle in the same way as it can be aged in a barrel. Spirits like whiskey certainly don’t either since the barrel aging is really about contact with charred wood.
You know, not to ruin the joke, but it might have worked out better if the Tecate did kill him back then. He's currently in prison for 45 years for stabbing his wife to death.
My parents had a can of tecate in their fridge dating to a 4th of July party we had in 1985... until finally around 2004, my brother's friend drank it. He didn't really have much of a comment on the quality.
