Jim Beam Double Oak is one of two expressions from the Beam distillery with the goal of enhancing the oaky wood qualities in their bourbons, the other being Devil's Cut. Double Oak takes standard Beam juice and simply ages it again in a second newly charred oak barrel for an unstated period of time, but likely less than 1 year by my guess. Enjoyed neat from a Glencairn. The short of it is standard JB profile with just a bit of extra oak and smokey char flavor. I like more oak forward flavors so this is enjoyable and cheap for a double oak, compared to something like Woodford DO. Nose is sweet corn with caramel toffee . Palate is sweet with more caramel vanilla and slightly more noticeable oak and char flavors. Pretty smooth neat sipper with easy heat and spice. Finish is sweet caramel and barely augmented by the extra oak, not an oak bomb by any means. A nice pleasant minty menthol lingers long into the finish with an enhanced char smokiness. In comparison to Beam's other "woody" bourbon, Devil's Cut, I find DO to be sweeter with more caramel flavors, and in particular an enhanced smoky char back note; whereas DC is far more astringent oak tannin driven with more wood barrel and less smoky char. Overall for the price a decent "extra oaked" bourbon. If you like slightly more oak forward flavors give this a try. It's not at all complex or even that interesting, but the extra oak on top of traditional JB bourbon flavors is nice if that's what you like. Compared to Devil's Cut, the DO is sweeter more caramelized with a more smoky undertone, while DC is more astringent oak tannin forward and less smoke. Part of me thinks the Double Oak naming here is more gimmick than what it really delivers, and I suspect it's because the overall length of aging just isn't long enough to impart more robust oak flavor, and the time spent in the second barrel is far to short to really matter. I honestly get stronger and better quality oak flavors out of other bourbons in the same price class, namely the delicious Wild Turkey 101 and even Bulleit, although bear in mind the overall flavor profile of these is unique and vastly different than JB. It's not that JB DO is a bad bourbon, but for a double oak I expect stronger more intense oak flavor, and this tastes like any traditional caramel vanilla forward JB bourbon really. If you truly want amped up oak with amped up traditional bourbon flavor in a JB product, you'll need to step up to Knob Creek, especially the SiB which is truly exceptional. Cheers!
