Traverse City Barrel Proof Bourbon is just what it sounds like — their signature XXX Straight Bourbon bottled in single barrel lots at cask strength. Each cask used is hand selected and placed delicately into the bottles uncut and au’natural. That’s why the ABV varies from 57.5% ABV to 60% ABV. The mach bill is simple — corn, rye, and malted barley. But the craftsmanship, flavor, and power are straight-up tasty.
