Calumet Farm 15 Year Single Rack Black Bourbon 750ML is a 15-year-old Kentucky straight bourbon bottled at 105 proof (52.5% ABV) in a 750ml bottle. What distinguishes this expression is its single-rack aging method — every barrel in a given batch sits on one center-cut rack inside the warehouse, producing a remarkably uniform flavor profile across all 19 barrels in each small batch.Quick Facts: ABV: 52.5% (105 Proof) | Origin: Bardstown, Kentucky | 15 Year Age Statement | Source Distillery: Barton Distillery | Non-Chill FilteredProduction & HeritageCalumet Farm bourbon is produced by Western Spirits Beverage Company, which sources its whiskey from the historic Barton Distillery in Bardstown, Kentucky — one of the oldest continuously operating distilleries in the state. The liquid is then bottled by Three Springs Bottling Company in Bowling Green, Kentucky. The mashbill runs 74% corn, 18% rye, and 8% malted barley, a rye-forward recipe that lends noticeable spice alongside the deep sweetness expected from 15 years in new charred oak. The “Single Rack Black” designation means each 19-barrel batch is pulled exclusively from barrels that aged together on a single, center-cut warehouse rack, eliminating the temperature and humidity variation that comes from blending barrels across different floors and positions. The bourbon is non-chill filtered, preserving the full body and mouthfeel that extended aging develops.Tasting NotesAroma: The nose opens with rich caramel and brown sugar, giving way to baking spices — nutmeg and cinnamon sit at the forefront. Behind them, dark fruit notes of cherry and apricot emerge alongside seasoned oak.Taste: The palate enters sweet and dense, with toffee and scorched caramel leading into candied cherries and ripe stone fruit at mid-palate. As the bourbon opens up, peppery rye spice asserts itself, balanced by warm brownie-like richness and a hint of cool mint. Oak tannins are substantial but well-integrated after 15 years, providing structure without bitterness.Finish: The finish is long and warming, with leather, black pepper, and toasted oak lingering well after each sip. A residual sweetness — somewhere between prunes and vanilla — anchors the dry, tannic close.How to Drink Single Rack BlackAt 105 proof, this bourbon rewards patience — pour it neat and let it sit for five to ten minutes, then add a few drops of water to unlock the fruit-forward middle notes. On a single large ice cube, the sweetness intensifies and the oak softens into a more approachable pour. For cocktails, the high proof and bold oak character hold their own in spirit-forward builds: an Old Fashioned, where the caramel and cherry notes harmonize with bitters and a sugar cube; a Boulevardier, where the tannic backbone stands up to sweet vermouth and Campari; or a classic Manhattan, where the rye spice and dark fruit play naturally against the cocktail’s aromatic profile.Best For

At 105 proof and non-chill filtered, the liquid retains a viscosity and intensity that many age-stated bourbons sacrifice for approachability. For drinkers who value transparency in sourcing and specificity in production method over brand mythology, this is a Kentucky bourbon that delivers substance and a clear point of view at 15 years old.
