A little late but I tried a couple of winter seasonals over the last several weeks and both were fantastic;
Hibernation Ale by Great Divide Brewing Co & Winter Solstice Seasonal Ale by Anderson Valley. If you can still find I highly recommend.
Also had The Beast by Avery Brewing. $7 for a 12 oz. but 16.83 ABV. and the taste was crazy. Probablly won't buy again but if you have money to burn it would be worth a try.
Have Fade to Black to try this weekend. Thanks Chingon.
