Well, that was fun.
Started with Southern Tier. Probably not a wise move, since it provided a skewed baseline for comparison. My immediate reaction: it's what Willy Wonka would brew. Whimsical, but still really well executed.
Elysian had four brews to sample. Dark of the Moon was their pumpkin stout, with hints of cinnamon, quite nice. Blight (the Beer of the Apocalypse) is a pumpkin ale also brewed with cinnamon; I found it a little malty for my taste, like a warmer. I did like their imperial, Great Pumpkin, and their Night Owl, both of which were brewed with pumpkin seeds, which added a nice roastiness to them. They were all pretty good.
Epic Brewing did a really nice pumpkin porter. Tried the Wasatch, which I did like, even though it was an amber. The Shipyard Pumpkinhead and the Smashed Pumpkin were OK, too, but only just.
I was getting restless/hungry by this point, so I left before trying them all (skipped on Uinta, Bill's, Brew Moon, and some pumpkin ciders). Last one I tried was the Dogfish Head, which actually left me a little wanting. Perhaps I had unreasonable expectations. I did think it had good balance, but maybe not as much pumpkin-ness compared to some of the others.
Bought a bomber of the Southern Tier on my way out. Might save that for later in the season; I may go back to drink the Pumpking while it's still on tap this week (and beyond?).
