Global Warmer had to do with the Christmas season. After reading the back of the can (yes, good beer can come in cans now) I saw the pun with Winter Warmer. I now can't imagine how I missed that.
Sixpoint Brewery's winter offering is like a strong IPA modified to be sweeter for the season. It has a hops-heavy taste, especially in a mouthful of that big, lacy head. It also has the full bitterness of an IPA, which goes surprisingly well with the lingering sweetness.
Three days, no disappointments. Thanks again Craft Beer Cellar!
