The worst beer I've ever tasted was from Dogfish Head, of all places. It proves even the best get it wrong sometimes.

It was called Raison D'Etre and it was made with raisins. Really. And you could taste raisin in every sip.

I'm embarrassed to admit I bought it a second time by mistake. I figured I'd try it again in case I just had a bad bottle. Nope, still gawdawful.
