I.W. Harper 15-Year is a refined Kentucky straight bourbon whiskey distilled at New Bernheim (Heaven Hill), then aged for 15 years in Stitzel-Weller warehouses before bottling at 86 proof. Its mash bill is 86% corn, 6% rye, and 8% malted barley. This bottle delivers a balanced profile with lush fruit on the nose—think cherry, apricot, orange, mint, and dark chocolate—followed by a palate of oak, caramel, leather, and vanilla. The finish is medium-length, featuring oak-driven warmth, vanilla, and lingering caramel. Recommended neat or on the rocks for savoring its nuanced, age-softened character.
