There's two different components of that. What do the locals call it, and what would a pre-apocalyptic connoisseur tasting it think it was. In the later case, it's probably almost all "horrible rotgut". Most of the fine distinctions people now make are hard to tell apart in pre-industrial products, let alone ones made by non-specialists with scavenged gear.

It should be possible to distinguish between brewed from grain/starch "beer", brewed from fruits "wine", and run through a still "spirits", but I wouldn't count on much more than that. Yes there is some fine craft production at low TLs that will produce distinctive products with something like batch to batch consistency, but that's in a stable low TL society, not a post-apocalypse.
