Master distiller Eddie Russell’s latest iteration in the Master’s Keep collection is a 10 year old bourbon matured in No.-4 char barrels and then finished in Jamaican rum casks selected by Appleton Estate’s master blender Joy Spence. The whole series has been triumphant, but this rum cask-finished gem shows Russell in tremendous form, serving up a joyous, chestnut-brown bourbon that delivers the best from both the whiskey and the rum influence. The promise of baking spice aromas, toffee, red berries, and black tea leads into an irresistible combination of cola flavors, vanilla, brown sugar, chocolate- cherry truffles, and ginger. —Jonny McCormick
