Kentucky Peerless Double Oak Bourbon is a small-batch straight bourbon whiskey produced at the Kentucky Peerless Distilling Co. in Louisville, Kentucky. The Double Oak expression begins as Peerless's signature small-batch bourbon and is then transferred into a second, freshly charred new oak barrel for an additional finishing period — a process that amplifies the wood-forward character while adding layers of complexity not found in a single-barrel maturation.

The mash bill is non-GMO corn-forward, distilled in a traditional pot still, and the spirit is bottled without chill filtration and with no added coloring, preserving the natural oils and full flavor profile. On the nose, the whiskey opens with rich vanilla, caramel, and toasted oak, followed by notes of dark fruit and baking spice. The palate delivers a creamy mid-palate with brown sugar, dried cherry, and a touch of leather, while the finish is long, warm, and lightly tannic from the double-wood treatment. Bottled at barrel proof (proof varies by batch, typically in the 108–114 range), each batch is a single release tied to a specific set of barrels. The 750 ML bottle is the standard retail format for this expression.
