At 100 proof and made entirely from rye, WhistlePig 10 Year Old is the straight rye that put the Vermont brand on the map. A decade in American oak rounds the grain’s natural bite into something richer: allspice, orange peel, and anise on the nose, then a sweeter palate of caramel and vanilla chased by rye spice and a cool touch of mint. The finish runs long on warm butterscotch. This is a benchmark 100-percent rye spicy enough to satisfy purists, polished enough to convert newcomers. It holds its own neat, but that backbone also makes it a superb base for a Manhattan or a Sazerac, where ten-year rye gives the cocktail real depth.
