Well, yes, I know what you mean but, to give JDW credit, they do have a
beer menu. Not sure how generally available it is, but I do know that they produce proper lists for their regular festivals. The lists even include the hops!
Nicholson's do the same and, personally, I'd like to see much more of this sort of thing to help me make an informed decision - if I like Copper Dragon Challenger IPA, I'd want to also try Hook Norton Jackpot, which both use Challenger, for example.
