Their review emphasized the wine's expressive aromas, noting "sweet and savoury coconut, dill, and Kirsch" with additional toasty oak, vanillin, and mocha. The reviewer described it as a "towering red" with fine-grained tannins and a burly texture, which eventually gives way to flavors of "spiced rum cake and rum-soaked raisins." The ripe, sweet fruit is balanced with a cool, aromatic lift, finishing with "earth, wet river stones, and dried herbs."
