Pretty much anything dark and or strong. Imperial Stout (or pretty much any stout besides Dry Irish), Porter, Wee Heavy, Barleywine, Doppelbock, Belgian Strong Dark, Dubble, Weizenbock, etc… I also like to do a big super hoppy IPA once the new hop harvest comes in, and I drink sours pretty much year round.
The problem with most big beer is that they need some time to mellow, so get brewing soon if you want to be drinking it this winter.
