Hidden on the second floor of Kimpton Gray hotel, Chicago’s sleek Vol. 39 is a spirit-forward bar where a menu of Old Fashioned variations and a six-Martini flight are de rigueur. The Spanish Armada by bartender Jessica Lambert is a layering of Lustau Brandy de Jerez, El Dorado 12-year-old rum, Lustau PX sherry and bitter Bigallet China-China amer. The drink’s peaty, nuanced secret? The Famous Grouse Smoky Black blended scotch. The savory spice layers unfold with Bittercube Jamaican No. 1, Angostura and The Bitter End curry bitters.
