James B. Beam Distilling Co. has announced the launch of its oldest Knob Creek release to date.

Knob Creek 21 Year Old (50% ABV) is a limited-edition Kentucky Straight Bourbon, crafted from whiskey casks that have matured for over two decades in the brand’s Kentucky rackhouses, weathering changing temperatures and seasons.

Each cask was hand-selected by the distilling team, led by Freddie Noe, eighth-generation Master Distiller, for its remarkable balance and complexity – proof that patience, instinct and respect for the craft can produce something truly one of a kind.

Knob Creek 21 Year Old is said to offer aromas of seasoned oak, caramelised sugar and subtle smoke on the nose, followed by flavours of deep caramel, char, hints of fruit and toasted oak on the palate.

Commenting on the launch, Freddie Noe, said: “When we first laid this batch to rest, we weren’t chasing any specific age statement – we were focused on crafting a great bourbon, just like we always do. After I tasted the whiskey, I knew we had something special. After decades in the rackhouse, the liquid developed a richness and balance we knew Knob Creek® fans and whiskey enthusiasts would want to experience. That’s what makes this release special: it’s bold, full of character, and embodies what Knob Creek stands for.”

Limited in quantities, Knob Creek 21 Year Old is now available from selected retailers across the United States, for a RRP of $249.99.
