Rabbit Hole Heigold Cask Strength is a high-rye Kentucky straight bourbon, mash bill 70% corn, 25% malted rye, 5% malted barley, bottled at full cask strength proof runs anywhere from roughly 100 to 125 depending on the barrel, no water added. This release carries one of the Artist Series’ commissioned illustrations, part of a rotating set of six original pieces from Rabbit Hole founder Kaveh Zamanian. The malted rye specifically (versus standard rye) gives it a rounder spice than a typical high-rye bourbon. Single barrel means this exact bottle carries its own specific proof and character. Start it neat, add water in small increments.
