Mainly barrel-fermented Roussanne, the 2018 Chateauneuf du Pape Blanc Clos de Beauvenir is a major success. Pencil shavings accent tropical fruit notes that include guava and pineapple. Full-bodied but structured, it's big, plush and ripe but balanced, with a lively testiness on the lingering finish. It should age a decade or more, depending on how evolved you enjoy your white wines.
