This new whiskey commemorates the rebranding of Rabbit Hole's core range paying tribute to influential figures in Louisville. This straight bourbon edition captures the spirit of Christian Heigold, a German who immigrated to Louisville in 1850. As a stonecutter Heigold built a mansion in The Point neighborhood of the city, decorating it with patriotic carvings and epigrams, including a bust of President James Buchanan. Rabbit Hole's Heigold, a Kentucky Straight Bourbon Whiskey made with a high percentage of imported German malted rye. Distilled from 70% corn, 25% malted rye, and 5% malted barley, aged for just under four years in toasted and charred new oak barrels.

A whiskey gets its color and character from the cask in which it ages and matures. This Double Cask whiskey goes through the process twice. The first five years of maturation in a new charred oak barrel makes it a bourbon. That bourbon then experiences secondary maturation in decades-old casks seasoned by Pedro Ximenez sherry that adds a touch of sweetness, and yields a smooth and impressively complex spirit.
