Released in 2021, Knob Creek 15 pushes further into the territory that the 12 Year began to map. Still bottled at the non-negotiable 100 proof that Booker Noe insisted upon, it takes the brand's hallmark Beam character and stretches it over fifteen Kentucky summers — a risky thing with bourbon, where a season too long can turn richness into sawdust.
This one walks the line well. The glass releases dense oak first, then dark toffee and stewed plum, with the particular smell of antique wood polish that long-aged bourbons sometimes give off. A curl of pipe tobacco rises behind it, promising weight.
The palate delivers. Molasses leads, thick and dark, followed by bitter chocolate and charred oak, black walnut and a whisper of old leather. The tannin is pronounced — this is a wood-forward bourbon, unapologetically so — but the sweetness is deep enough to carry it. At 100 proof the spirit holds together; the alcohol is present but never sharp, and the texture is genuinely chewy.
The finish is the longest of the Knob Creek age-stated range, drying and tannic, with espresso grounds and the ghost of a spent cigar. Not every palate will want bourbon this wood-driven, and that is fair — fifteen years is a long time to ask a barrel to hold its tongue. But for drinkers who love the darker corners of Kentucky maturation, who collect bourbons the way others collect first editions, the 15 delivers a serious, brooding pour that demands attention and rewards patience.
