We check out Firestone Walker's Old Man Hattan. It's a barrel-aged mashup of two classic cocktails; the Old Fashioned and the Manhattan. From their website, "This inaugural Proprietor's Vintage release features a blend of five notable Firestone Walker beers, including select lots of Parabola and Helldorado aged in cherry, orange and aromatic bitters barrels. "
It was originally a Black Friday release available only at the brewery, but was popular enough to become a limited release in their Vintage series.
