New Riff Distilling's Single Barrel Bourbon expression is a full bodied whiskey offering vibrant, spicy character. Bottled at Barrel Proof Without Chill Filtration, and featuring a high-rye mash bill of non-GMO grains at 65% corn, 30% rye, and 5% malted barley, it represents a new riff on one of the most influential of modern whiskey traditions. Aged four years in 53-gallon toasted and charred new oak barrels, there are no shortcuts taken in our production.
