Nothing beats a single-malt scotch from Laphroaig! Give me a 15 year or Quarter Cask straight any time of the day and I'll be happy.
If scotch is getting too pricey (never), I'll settle for a nice stout. Not a laughable attempt at a stout like Guiness, but a man's stout.
My personal favorite is The Abyss by Deschutes.
I'd also recommend grabbing yourself a bottle of Stone's Russian Imperial Stout:
Perhaps if you're in my hometown over December, you might want to grab yourself a bottle or two of Darkness, because they're only out once a year and only at the brewery, but ranked top 10 (right next to the Abyss).
And to give Colorado some love, if you're lucky enough to find a can of this, it's the darkest stout I've ever had, and a favorite of everyone I've ever recommended it to:
Oscar Blues Ten FIDY! Yummy.
And while searching through Colorado beers, buy a Coors light! Kidding... but a Yeti or Oak Aged Yeti Imperial Stout
Speaking of, I need a beer.
