Boulder Bourbon Bottled in Bond is a straight Kentucky bourbon meeting the strict U.S. Bottled-in-Bond regulations—100 proof, aged at least four years, and produced at a single distillery in a single season, bottled at 50% ABV. The nose opens with oatmeal cookie, candied ginger, and caramel. The palate delivers cola, peanut brittle, dark fruit, and a long, warming oak finish.
