Made a winter-brew run through the mega store this weekend just to try a few out:
Sam Adams Winter
Celebration by Sierra Nevada
Harpoon warmer something...not a fan at all
Full Moon by Blue Moon
Out of those four, sampled side by side of course, my favorites are Sam Adams and Celebration. Harpoon just is too spicey for me and Full Moon doesn't have much distinction to it.
Also picked up some 2 Below from New Belgium which is my favorite overall.
