I like to think of IPAs as more Summer and Spring ales, but I like them so much i'll drink them year round. Conversely, I typically reserve most of my heavier stouts, porters, pumpkin, and the like until the weather turns. I've been sitting on a bottle of Chocolate Oak Aged Yeti since May! But I do notice that a lot of my favorites do come out in the Fall for Winter. Its a good time of the year for good brews.
