Sweet, gentle, and full of flavor, WhistlePig 15 introduces itself with notes of oak, vanilla, soft rye spice (can vanilla be spicy?), lemon peel, and barrel char. Similar to the nose, it slowly evolves towards the back of the palate with more juicy red fruits, dark chocolate, and more creamy vanilla. There is a small undercurrent of herbal and vegetal notes but that is fairly restrained and never impedes on the complexity of the palate.
