I'll drink a sixer or so per season, I find it to be a decent beer if done properly. But part of "properly" means using the right ingredients. In this case that means pumpkins, not pumpkin extract. If the beer is done now, it was brewed sometime June/July? Don't know about anyone else, but I've never seen a fully grown pumpkin in the middle of summer . . .
Personally, I think they are to be enjoyed in October/November.
