Leopold Bros. 5yr BiB Straight Bourbon Whiskey, Denver, Colorado (750ml)
Producer notes ~ "43% ABV / 86 Proof 64% Corn 15% Rye 21% Malted Barley We begin by fermenting a traditional sour mash of corn and rye at colder temperatures, but without the aid of refrigeration. Fermentation takes more time this way, but results in a softer whiskey and develops subtle flavors such as vanilla, pear, and raspberry. We then distill the mash in our small batch copper potstill on grain to extract fuller and rounder flavors from the corn and rye. Finally, we barrel the distillate at the Pre-Prohibition standard of 98 proof, so that the barrel may add subtle notes of oak and vanilla and does not overpower the finished whiskey."
