I've been hearing a lot about black beer what's a good one to try
Agreed - Guinness...just don't have it too cold !
Sam Adams has a good one. Kostritzer is another good one but its a german brew. Idk where you would even find it in the U.S.
21st amendment back in black and new Belgium 1554 are good. Stone vanilla bean porter is even better. If you like chocolate, try youngs chocolate stout.
