WhistlePig Rye 10 Year is a 100 proof &100 percent rye whiskey, aged for at least ten years through a unique double barrel process. Warm wooden notes from the 3 year oak bourbon cask aging give way to hints of vanilla, caramel, dried orange peel, cinnamon, allspice and clove. Later, dark chocolate and peppermint notes appear. The finish is an almost creamy flavor, leaving notes of vanilla, orange, and caramel, before hints of dark chocolate linger on the tongue.
