When I was picking up my fall seasonals last night, they guy at the shop, who often travels to NY for wine (and beer) said that this year, Southern Tier was releasing a new Christmas beer called 2XMAS.
Looking in to it, I found a bit more.

With the success of Pumking, I'm really looking forward to this new winter seasonal.
