This Jeffersons Pritchard Hill release is aged using quite a unique maturation technique; a twin wood aging process, that incorporates a blend of three complex, elegant bourbons that have been aged for one year in new American Oak barrels, and finished in ex-Pritchard Hill Cabernet Sauvignon French Oak casks. The special casks were once situated at the highly elevated, rocky slopes of the Chappellet Vineyard in St. Helena, Napa Valley. “The wine barrels that matured the most sought-after wine in the Chappellet portfolio lend a sweetness to the bourbon by adding notes of dark berry, espresso, and chocolate” (Jefferson's).
