Given the difficulty with Grenache in 2013, the Grenache-dominated 2013 Chateauneuf du Pape Imperiale (Vigne Centenaires) is a head-turner that offers terrific notes of plum, black cherries, mulberries, dried flowers and licorice. Brought up all in concrete tank, this medium to full-bodied, ripe, textured, yet structured Grenache will be better in a year or three, and drink well through 2025.
