Was that the “Winter Bourbon Cask Ale”? Now THAT was bad beer, in the same sense that snackwells are a bad food. Artificial-tasting flavors, too much sweetness, etc.
Taste is subjective. But, when judged against the schema that describes the domain of “beer” as a whole, you can say that some beers do a poor job of representing the attributes that a beer, by definition or by historical example, should have. That doesn’t mean someone can’t enjoy drinking it.
Actually I had the chance to try AB’s RyePA(yeah, that’s the name(at least it’s not Wry Smile)) and it was actually bitter. Not in a Hop Ottin or Hop Rod Rye way but more than SNPA. This would be a good go to beer if sold separately
