Been drinking a ton of pumpkin beers lately. So far, Schlafly's Pumpkin Ale is my favorite.
Flying Dog Fear is pretty solid too.
One that surprised me a bit was Shocktop's Pumpkin Ale. I'm not a big Shocktop fan, but it had a nice pumpkin flavor to it.
Bought some Sam Adam's Fat Jack to try this weekend. I'm hoping its really good, but I've heard mixed reviews so far.
