My favorite time of year comes again as my wedding anniversary and the Christmas season begins in full swing, but this time with a new Knob Creek product to celebrate. Many years ago, my wife and I chose a special single barrel of the 9 year bourbon that we enjoyed only on our anniversary each year. As the bottle finally emptied last November, we began thinking of what would fill that gap in our ritual. We took a trip to Jim Beam to try to gain any inspiration, and that's when we discovered that an 18 year bourbon was taking the place of the previously offered 15 year counterpart. It was an obvious choice, and even though it was purchased in January of 2024 (many months after it's autumn release) and directly from the distillery, I still somehow paid $10 more than MSRP, because, you know, economics. We engraved this bottle just as we did the previous one, but panicked at the time and simply engraved the day we bought it instead of any other significant date. This review will serve as my first taste of this spirit, with repeated drinking to only occur that each anniversary day, when the Christmas tree has already been put up for several days, and celebration is in the air. Let's hope this new placeholder, double the age of the previous bottle, yet proofed down atrociously so, helps to keep the Knob Creek name just as special in our household. The age combined with the heavy barrel char really do come through on the color, giving the inner body an old maroon, rosy berry mixed with a deep, nutty, almost chocolatey brown, although unfortunately also a watery outer edge due to the proofing down. The ethanol is surprisingly potent through the nose, but I've yet to have any whiskey from an American distillery that was able to capture the scent of a rickhouse so perfectly, until now. The sweet oak is abundant, but not sugary or heavy, with a much smaller amount of vanilla, black cherry, lemon, and spicy, aggressive rye balancing well and making way for something much more developed than the younger age. The flavor begins simple with sweet oak, but not with the secondary objectively sweet flavors I usually find, like chocolate, caramel, toffee, or otherwise. Instead, this is able to deliver the natural sweetness from the wood sugars, and nothing more, save for a touch of black cherry, but mostly keeping the focus on the age and the development. Speaking of development, the base grains no longer have any flavor on their own, but their effects are still present. For example, the rye still delivers a spice in the gums that lingers, and the corn, given the time it so desperately needs to mellow and marry to the oak, delivers the rounded, full body that makes this an entirely different drink compared to grain-forward bourbons without the age under their belts. The finish is hot but approachable, keeping the proof balanced, and bringing forward a dry note alongside a return of the naturally sweet oak. I keep going back with hopes of finding deeper flavors like tobacco or leather, but I think the added water took these options away, sadly. What we have here is indeed an excellent tribute to what a good bourbon can, and should, be. Sure, I personally would enjoy this at cask strength, but lord knows how much more I'd be charged for this same product if that were the case. Additionally, there's no arguing that 100 proof is essentially a perfect proof point for anyone who enjoys drinking whiskey neat and hunting for the flavor, and although $10 per year aged is far too much when you get to this point (especially considering most European whiskies would trump that figure when it comes to price versus age), there's still the part where this tastes objectively pretty good. It will always remain impossible for young, impatient distilleries to create this flavor profile from a product with just a few years in the barrel, but until the availability and economics of American whiskey allows these higher age statements to not only be affordable, but to even be found on the liquor store shelves, this isn't worth paying an arm and a leg for, but it will make an elevated toasting whiskey for an anniversary each year, so there's that.
