WhistlePig 18 Year Double Malt Rye is a limited-production American rye whiskey crafted from a distinctive mash bill of rye, malted rye, and malted barley. Aged for 18 years, it combines bold rye spice with softer floral, earthy, and toasted malt characteristics. The result is an elegant, complex whiskey with exceptional depth and a long, refined finish.
