The yin to the yang of the estate's Mourre des Perdrix bottling, the 2019 Chateauneuf du Pape Cuvee Vieilles Vignes is almost all Grenache (10% Mourvèdre) from stony, galets roulés sites in Coudoulet, la Crau (sud) and Cristia. It's all black cherries and mocha on the nose, then full-bodied and rich but rather coarse and open-knit on the palate. It's long on the finish and shows remarkable intensity, but it doesn't have the same degree of elegance as the other offerings from Charbonniere; perhaps that will emerge with further cellaring. A second sample (tasted nonblind) revealed more of that elegance, with an almost airy, ethereal feel on the palate that belied the wine's enormous concentration and power.
