Mainly barrel-fermented Roussanne, with the balance typically Grenache Blanc, the 2019 Chateauneuf du Pape Blanc Clos de Beauvenir remains a standard-bearer among white Chateauneufs. The vanilla and toasted-nut shadings are subtle, just adding a touch of complexity to the ripe pear and tangerine aromas on the nose, while the full-bodied palate remains vibrant and zesty despite its voluminous feel in the mouth. Long and silky on the finish, this is not only powerful and flavorful, but elegant. It should drink well for a decade or so.

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.

Consistently one of the most age-worthy whites in the appellation, the 2017 Chateauneuf du Pape Blanc Clos de Beauvenir continues that tradition, framing gentle citrus fruit notes in a delicate frame of pencil shavings and vanilla from new oak. It's full-bodied and richly textured, easing into a lively finish of lingering lime zest.

One of the few whites from the appellation I would be confident in aging is La Nerthe's 2016 Chateauneuf du Pape Blanc Clos de Beauvenir. It's roughly 80-20 Roussanne and Grenache Blanc, fermented and aged in demi-muids and barriques, yet it is tight and focused. Stone fruit, melon and tangerine on the nose give way to notions of honey and bergamot on the palate.

Not yet bottled, the 2015 Chateauneuf du Pape Clos de Beauvenir Blanc is more fresh and steely than previous vintages, yet still has medium to full-bodied richness, terrific notes of apple blossom, brioche and crushed rocks, impeccable balance and a great finish. I suspect it will benefit from a year in bottle and keep for a decade or more.
