Knob Creek Aged 21 Years Kentucky Straight Bourbon Whiskey (750ml)

Product Description

Knob Creek Aged 21 Years Kentucky Straight Bourbon Whiskey 750ml is a monumental, ultra-aged release that represents the absolute pinnacle of Knob Creek’s barrel program. Curated by blackbook for its rarity, maturity, and unmistakable Beam family character, this bourbon showcases what happens when exceptional barrels are given decades—not years—to evolve.

Aged a full 21 years, this bourbon delivers profound depth and concentration. Extended time in charred American oak brings layers of dark caramel, leather, tobacco, roasted nuts, and seasoned oak, all balanced by Knob Creek’s signature sweetness and structure. Despite its age, the profile remains composed and deliberate—rich and powerful without tipping into bitterness.

At blackbook, we reserve space for bourbons that define categories. Knob Creek 21 Year does exactly that: a statement whiskey for collectors and serious drinkers who appreciate patience, precision, and legacy.
