The 15-Year-Old Straight Rye Whiskey from WhistlePig, is an exceptional expression representing the brand's oldest and most mature release to date. This rye whiskey undergoes a unique finishing period in custom Vermont oak casks, meticulously crafted with an extended toast and a heavy char. Sourced from local forests, the Vermont oak—shaped by shorter growing seasons and rigorous winters, develops a notably tight grain structure. This imparts a distinctive terroir to the spirit, enhancing its complexity and elevating its flavour profile with a profound sense of place.
