Three Floyd's, since it was the first brewery that I made an effort to visit. I consider their Christmas beer, Alpha Klaus, to be a gift given directly to me from them.
Alpha Klaus pours out a dark red almost black oily color with a light tan head. The head sits atop the beer like dirty snow covering a dark mud puddle... sorry not my best analogy. It left lacing up to the top of the glass like frost on the window... better. It had a abv of 6% and 38 IBUs.
The beer smells like chocolate and grapefruit hops with a bit of piney-ness. It smelled hoppier than most of the Christmas beers I've had this season. It was also a bit thinner and more effervescent than I expect from a Christmas porter.
This is a fun and unique holiday beer. I don't know that I would be excited to drink it all the time, but it will always make me smile during the holiday season.
Hoppier than I like but I give it a 3.5
