Nose: Oak, vanilla, brown sugar. Fruits - bananas, apricots, peaches, blueberries. Cinnamon leads the baking spices, though there's a solid clove punch as well. That oak is absolutely present, but not overtaking the rest of the glass - everything else is still able to shine through. Well worn leather. Undercooked roux, with a butter plus raw flour thing going on. Barrel char and smoke are also present, but again aren't overtaking the rest of the show. Compared to standard Knob Creek 9 year, this is deeper, richer, and has more fruits, while the black pepper and spices aren't as "front and center". Palate: Dry and tannic oak, with brown sugar and some vanilla extract. Under-ripe bananas, strawberries, and blueberries are also here. Floral alongside classic baking spices - toasted anise, camphor, black pepper. Lightly sweet ketchup-based barbeque sauce, smoked ham, and charred beef. Again, this is almost exactly what you have in mind when imagining Knob Creek but older. The depth of fruit here is a welcome addition, but never turns into extreme territory - balance here is superb. Getting reminded of the Red Bull cola - should see if I can't order that online. Middle and back palate heavy, with a nice little pop on the front. This fills in the bass that's missing from standard KC. Medium mouthfeel, but with enough tannin texture that it almost presents as more dense. Finish: Big pop of ethanol, citrus peels, and flowers. That signature oak character comes forward, alongside honeyed grains and fruits. Big time parfait with overcooked granola vibes. Bitterness and texture show up and the proof is still hanging out. There's an effervescence to the finish that I find really enjoyable. Medium long length. Other notes: Knob Creek 9 year is my favorite daily sipper. It's the single bottle that I will go out of my way to ensure I have in my cabinet. So any time I come across anything new under that label I buy on the spot. This 15 year simply reinforces that strategy - this is a beautiful expression, and while I wish (as I often do) that it were at a higher proof, I am by no means disappointed. The overall integration and balance on the nose, palate, and finish show some masterful blending that showcase a well aged bourbon that isn't over-oaked. This sits very comfortably in the Knob Creek flavor profile while also showing what advanced age can accomplish with that mash bill. Really beautiful bottling. I can absolutely recommend it.
