Closer to the heart of JW than its predecessors, Mastery of Oak follows a methodically complicated maturation and blending regime. American oak characteristics, singed cedar spills, damson jam, stewed apple, and rhubarb laced with peppery spice, nutmeg, and clove. A dichotomy of flavors: toffee apple and rhubarb become piquant, verging on sour, with a parallel strand of honey and Caramac. Short finish of the last vestiges of fruit and spice.
