Bulleit Bourbon Frontier Whiskey Barrel Strength Uncut Limited Bottling 750mLBulleit Barrel Strength is medium amber in colour, with gentle spiciness and sweet oak aromas. The mid palate is smooth with tones of maple, oak, and nutmeg. The finish is long, dry and satiny with a light toffee flavor, but with deepened oak notes. Because Bulleit Barrel Strength is being bottled straight from the barrel, uncut and unfiltered, the ABV will vary by batch, but will generally range from 120 125 in proof.
