The 2015 Chateauneuf du Pape Cuvee Prestige Blanc switches up the varietal mix. A blend of 80% barrel-fermented Roussanne with steel-fermented and aged Grenache Blanc and Clairette, it offers up toasty, nutty scents of roasted cashews, pineapple and coconut. It's a cavalcade of bold flavors, broad on the palate yet long and briny on the finish. It should prove capable of aging up to a decade, but I'd opt for drinking it young for its flamboyant exuberance.
