Pumpkinhead is pretty light, it's a light color, light alcohol percentage at 4.5% and relatively inexpensive, I think I paid maybe $8 for a six pack. It's sweet and a bit tart, it's pleasantly crisp and finishes with cinnamon and pumpkin, lightly. This is a good beginner's beer for those dipping their toes outside of the Bud pool and into the neighbor's deep and mysterious pool.
So, getting back to the cinnamon/sugar rim, if it's offered, go for it. I think it definitely enhances the pumpkin pie in a glass thing. But. I kind of wish it wasn't necessary, the beer could be a bit more complex in it's profile, but to that effect, if I want a more complex beer then perhaps I should be drinking one.
Well, I guess I'm done arguing with myself.
In conclusion, it's a good easy to drink beer for a cool fall day. Despite it's short comings, I wouldn't kick it out of my bed...but I'd be thinking of another seasonal beer while we snuggle.
