WhistlePig Old World Rye Aged 12 Years is a premium aged rye whiskey inspired by traditional European wine-finishing techniques. After extended maturation, the whiskey is finished in a combination of Old World wine casks, adding layers of fruit, spice, oak, and richness to the naturally bold character of rye. Bottled at 86 proof, it offers an elegant balance of sweetness, spice, and mature oak.
