Rabbit Hole Heigold Bourbon start with a unique mash bill of corn, malted German rye, and malted barley to give this bourbon a base of southern sweetness layered with light notes of white pepper. It is then barreled in charred American White Oak and mellowed in the sweltering summers and frigid winters of Kentucky for over 3 years. Infusing flavors of butterscotch and baking spices.
