Our Four-Grain Bourbon Whiskey is made of 60% corn, with the balance being a mixture of rye, wheat and malted barley. It is the only such Bourbon of its kind on the market, as most distilleries stop at three grains. it rich color and depth of character is a result of the unique combination of grains employed coupled with the small barrel aging process. Every single bottle is hand-filled, hand-corked, hand-waxed, hand-labeled and hand-numbered.
