Knob Creek 21 Year Bourbon 750ML is a highly anticipated and ultra‑aged limited release from the Knob Creek brand, celebrated for delivering an intensely mature, oak‑forward experience and complex flavor layers. The whiskey is bottled at 100 proof (50% ABV) and features a deep, dark color typical of older bourbons. Reviewers widely praise its robust flavor profile, describing bold waves of charred oak, dark caramel, brown sugar, and deep spices. Notes of vanilla, cherry, orange marmalade, and dried fruits accent the palate, while the oak intensity—described as “lingering forever”—becomes the dominant theme, only recommended for those who love the wood influence in their bourbon. Tasting Profile Nose: Aromas open with dark sugars, vanilla, toasted wood, and soft leather; hints of cherry and orange peel can be found. Palate: Exceptionally rich and full‑bodied, showcasing robust charred oak, caramel, brown sugar, and dark spices (clove, cinnamon). Fruit undertones (cherry, orange marmalade) add complexity, and lingering tannins keep the finish lengthy. The 21‑year age offers even more oak than the (already woody) 18‑year, appealing to enthusiasts who prefer deeply aged bourbon. Finish: Very long‑lasting and oak‑driven, punctuated by sweet vanilla, cola notes, and dried fruits. Mouthfeel: Medium‑thick and viscous, with a luxurious, coating texture.
