Nose: The first time in a long time I've experienced a nose this strong - actually made me laugh a little with excitement. Proof is absolutely evident and helping things jump out of the glass. Over-smoked brisket, like when it borders on bitter smoke. Bacon with a black pepper crust. Lemon oil, wintergreen, pine. Slight sweetness - almost like molasses. Brine. Green bell pepper, fire roasted poblano, smoked chipotle, paprika, bitter chocolate. Imagine all the sliders for a mix pushed up to 10, and then all the eqs pegged with a little brick wall compression thrown onto the master bus like a modern dance track. It's not completely unbalanced, just very forward.
Palate: Earth, vanilla, fruity sweetness. The casks are absolutely evident on the nose, but in a very complementary way. Oak, tannin, and char, though the tannin influence is less than you'd see in something with more age. Dark fruits in syrup. Citrus, mint, cucumber - getting a Limon Pepino Gatorade vibe, but with some mint tossed in for good measure. Creamy and lactic. Peanut brittle, dusty corn. Wintergreen. Tar and resin. Sandalwood and tobacco. Chocolate with a touch of smoked chipotle. Pop Rocks style effervescence. Mouthfeel is medium, bordering on medium-heavy.
Finish: A wash of brine, dust, earth, citrus, vanilla, and oak. A swell of dill and anise show up, followed by some cocoa. Some slightly bitter and sour characteristics play around, when coconut, sandalwood, and maduro tobacco come in. The citrus, mint, sandalwood, coconut all hang out for a long time - great oil content here. Very long finish.
Other notes: I'd long wondered what you'd get if you aged a heavily peated whiskey on the shorter side and instead let the more intense, raw flavors come through. Though this makes good use of sherry cask to help make things a little more palatable, I almost wish this was just pure second or third fill bourbon instead, minimizing the influence of what the barrels held. That put aside, this is like Uigeadail if it took off the smoking jacket and slammed three Black Eyes from Starbucks. It's not as refined and cohesive, but it offers up something unique and well worth some exploration. Highly recommended.
