WhistlePig The Boss Hog V "The Spirit of Mauve"

13 years. Calvados cask finish. The fifth edition of WhistlePig's annual Boss Hog series — named for Mauve, the farm's legendary pig, and her undying love of apples.

The Boss Hog series is WhistlePig's annual flagship — each edition a single barrel, bottled at proof, with a finishing cask chosen for its specific contribution to the rye's character. The Spirit of Mauve is finished in Calvados casks: French apple brandy barrels from Normandy that impart a distinctive apple sweetness and delicate French oak character to the already powerful 13-year straight rye base.

The result is exactly what WhistlePig describes: a unique blend of American rye power and French sophistication. The high-rye mashbill brings bold grain spice and structure; the Calvados finish layers apple, pear, and a subtle brandy richness over the top. There is nothing else quite like it in the American rye whiskey category.

Each bottle is hand-bottled at WhistlePig Farm in Shoreham, Vermont. The packaging — a coffin-shaped box — is as distinctive as the whiskey inside.

Tasting Notes

• Appearance: Deep amber with warm orange highlights.
• Aroma: Apple, cinnamon, vanilla, warm rye spice, and a subtle pear note from the Calvados finish.
• Palate: A harmonious balance of American rye power and French apple brandy influence — spiced apple, warm oak, vanilla, and a bold rye grain foundation.
• Finish: Long and smooth — apple sweetness and warm rye spice in perfect equilibrium.

What Is Calvados?

Calvados is a French apple brandy produced in Normandy, aged in oak casks. The casks absorb apple and pear fruit character alongside French oak influence over years of maturation. When used to finish rye whiskey, they impart a distinctive orchard fruit sweetness that complements — rather than masks — the bold grain character of aged rye.

Frequently Asked Questions

• What is the Boss Hog series? Boss Hog is WhistlePig's annual limited release — each edition a single barrel, bottled at proof, with a unique finishing cask. Previous editions include Maeve the Illusionist (Caribbean rum barrels), The Independent (straight from Vermont), and The Samurai Scientist (Japanese Umeshu). Each is a one-off that will not be reproduced.
• What does Calvados cask finishing add to rye whiskey? Calvados casks previously held French apple brandy, imparting apple and pear fruit notes, delicate French oak character, and a subtle brandy richness. In a bold 13-year rye, the effect is a softening of the grain's intensity with orchard fruit complexity that adds dimension without obscuring the rye character.
• How does Boss Hog V compare to Boss Hog VI (Samurai Scientist)? Both are single barrel, bottled at proof, with unique finishing casks. Spirit of Mauve uses Calvados (apple brandy) for a fruit-forward, Franco-American profile. Samurai Scientist uses Japanese Umeshu (plum wine) casks for an entirely different East-West character. They represent two different directions from the same exceptional rye base.
• Is WhistlePig Boss Hog V a limited release? Yes — like all Boss Hog editions, Spirit of Mauve was produced in limited single-barrel quantities. This is not an ongoing expression and will not be restocked once sold out.
