A terrific base cuvée that readers should seek out is the 2015 Chateauneuf du Pape Blanc, which is made from 80% Roussanne, 10% Grenache, 5% Clairette and 5% Bourboulenc. It offers classic notes of white peach, buttered citrus and that rocky minerality that’s reminiscent of the smell when you smash two rocks together.
