Proprietary four-grain mashbill of rye, heirloom blue corn, yellow corn, and malted barley. Contract distilled at Ross & Squibb (MGP) in Lawrenceburg, Indiana, then barreled and aged in Colorado Springs at 6,100 ft elevation. A touch of Smokeye Hill Barrel Proof Bourbon is blended in, making this a blended rye rather than a straight rye. Aged 5 years, bottled uncut and unfiltered at barrel proof.
