Finally, for those who have need of something tart, dark, and sour this year, check out The Bruery's intriguing Tart of Darkness. The base beer is a simple stout, but The Bruery—experimentalists through and through—age it in oak barrels with a proprietary blend of souring bacteria and yeast. The result is a sour stout that is one of the best beers I've tried recently. Powerfully flavorful and complex to no end, the tartness is rounded out with a smooth sweetness from the roasted malts and an unexpected, almost red wine-like tannic structure. The flavor profile changes almost from sip to sip, with nutty richness giving way to waves of face-puckering sourness. For a food pairing, think about complimentary flavors, like tart goat cheese and dried sour cherries. And, if you must, you could even drink it with a heart-shaped box of dark chocolate candies.
