BFM AKA Brasserie des Franches-Montagnes (you see why we abbreviate it!) is one of the most iconic barrel-aged beer producers in the world. Founded in in Switzerland, this beer is their flagship and a gorgeous and deep sour beer and is a blend of older and younger beers for complexity and freshness. Drink this with your Christmas goose, dark chocolate cake, or by the fire. Or anywhere else, really.
