I suppose if it were a single bad bottle, it would be undrinkable in a countable way. If you don't drink Jupiler (or American light beer, or whatever) the problem is with all of it--the undrinkability is not related to the countable nature of what it's packed in, whether that's bottles or kegs or vats.
Same for English--you may drink four beers, but you would not say, "I don't drink those sorts of beers" if you were talking about a single brand. It would mean, e.g., "I don't drink C**rs nor Mi!!^r nor B#sch."
