Pumpkin beers are extremely variable. I tried three at the big tasting the other day -
Wilhelm Scream from Magic Hat was excellent - the pumpkin was understated, but there, not too "spicy", very nice.
Du Claw 31 was ... ugh. WAY too sweet, weird spices (the flavor was
not "pumpkin pie" like), and smelled a bit like... I dunno, kerosene?
Erie's Johnny Rails Pumpkin Ale was more moderate than 31, but not as good as Wilhelm Scream. The spicing was right, more pumpkin pie flavored, not too sweet, but still a lot more pumpkin-y than Wilhelm which means it would be too much after one or two.
In other news, this was
very good. Guinness has beat the big American breweries at their own game...
