WhistlePig GraveStock is a limited-edition American wheat whiskey born from a collaboration between Vermont-based WhistlePig Whiskey and Liquid Death, the canned mountain water brand. Built on an 85% wheat and 15% WhistlePig Farm rye mash bill, this spirit is aged in new American oak barrels before being finished in custom casket-shaped 380-gallon American oak foeders — a first-of-their-kind vessel designed to reflect Liquid Death's signature death-and-metal aesthetic. The whiskey is bottled at 86 proof (43% ABV) and proofed using Liquid Death Mountain Water, a deliberate choice by head blender Meghan Ireland, who notes that water quality influences flavor during dilution.

GraveStock pours a bright golden amber with a nose of honeysuckle, sweet biscotti, butterscotch, caramel, and fresh bread crust with subtle herbal top notes. On the palate it is smooth and wheat-forward, delivering notes of maple cake, toasted nuts, sweet vanilla, honey, and baked brown sugar. The finish is clean and refreshing with lingering spicy biscotti and sweet caramel. This release continues WhistlePig's creative collaboration series, which has previously included CampStock (charred barrels by Solo Stove) and SmokeStock (Traeger apple barbecue wood) editions.
