The ninth edition in The Boss Hog series was crafted by WhistlePig's Head Blender Meghan Ireland and Head of Whisky Development Liz Rhoades who were inspired by the Nine Muses of Greek mythology. Each limited edition straight rye whiskey bottling is aged in American oak and then finished in two types of seasoned casks — Greek fig nectar and farm-scratch Tentura, a Greek liqueur. Notably, both finishes were made by the Vermont distillery team using Greek and local ingredients. These are single barrel expressions bottled at cask proof so the proof ranges from 12.5-16.2 (51.3-53.1% ABV). The nine Greek sirens and their respective art adorn this year's bespoke pewter toppers. Collectors should try to find Melpomene, the Muse of Tragedy as this is the most limited topper available.
