Blueberry Dark Sour by 12welve Eyes Brewing: It’s always a good sign when I think about a beer and start craving it immediately.

I tend to drink sour beers in the summer, when their quenching qualities are welcome, but this brilliant dark beer is like jam on pumpernickel toast and feels just right, even in the middle of a polar vortex.

Owner Elliot Grosse said they use a dark English malt that provides color and a hint of chocolatey flavor without a lot of burnt, smoky characteristics. That, combined with a ton of blueberry puree, makes for one of my favorite beers so far of this memorably, ridiculously cold winter.

Bonus: It’s low in alcohol, so feel free to have a few.
