Though made with the same sour mash regimen and high-rye mash bill of 65% Corn (non-GMO), 30% Rye, and 5% Malted Barley as New Riff’s core bourbon, this single barrel selection boasts an individual flavor profile and proof. Non-chill filtered and aged a minimum four years, expect full and bold flavor with distinctive characteristics that will change with each barrel selected. Bottled at cask strength, ABV varies from batch to batch.
