WhistlePig Boss Hog IX Siren's Song

The ninth edition of WhistlePig's annual single barrel limited release program — Siren's Song. Single barrel. Barrel strength. Vermont straight rye with a multi-cask finishing influence drawing from Caribbean rum and Madeira traditions.

The Boss Hog series is WhistlePig's annual pinnacle expression — each edition concept-driven, barrel strength, single barrel, and thematically named. By Boss Hog IX, the series had achieved international recognition through its preceding editions' critical acclaim, including the Boss Hog IV Black Prince's Best In Show Whiskey win at the 2017 San Francisco World Spirits Competition. Siren's Song is the ninth chapter: a mythological reference to the irresistible, complex call of an extraordinary barrel-strength rye.

Each Boss Hog edition explores an exotic finishing influence beyond the standard Vermont rye maturation. The IX Siren's Song incorporates finishing cask elements that draw from maritime and Madeira wine traditions, adding layers of tropical fruit, dried wine character, and exotic spice to the Vermont rye's foundation. At barrel strength, these finishing influences are delivered at maximum intensity without the softening that dilution introduces.
