I had a bare knuckle Stout in a Black&Tan with Bass, very nice. Not had one alone to comment.
The one off the top of my head is Sam Adams Old Fezziwig Ale. After hearing the horror stories my buddies told I just had to try one. And I finished it to give it a chance. The taste is just wrong. I will drink GALLONS of other Sam Adams

, Old Fezziwig Ale gets the big
Oh and any beer that its main sell is fruit. Just because its called Apple Brew, does not make it beer nor does it make it tasty as it may sound. The sole exception to this rule is the Unibroue Éphémère. Apple and Black Current both very tasty, though I can only have a 12 oz to sip on. They come in 750ml bottles but its just to much.
