Sweet and spicy, with a generous dash of vanilla, this is a treat.1 Four Roses Single Barrel – Bottled at 50% ABV and is comprised of their OBSV recipe (Four Roses has 10 different recipes). That means that this a straight whiskey using their high-rye mash bill (60% corn, 35% rye, and 5% malted barley) and uses their light fruity yeast strain.
