New Scotland Spirits Helderberg Bourbon Whiskey has a grain bill of 60% corn, 25% rye, and 15% malted barley all grown in upstate New York. A 99 proof spirit aged a minimum of 5 years in new charred white oak barrels, this traditional "high rye" bourbon delivers the perfect mixture of bourbon's sweetness with some nice rye spice. Notes of cherries, toffee, leather and oak make this a delicious sipper or great in an Old Fashioned or a Manhattan.
