The very limited production and single greatest white wine of the southern Rhone is their 100% Roussanne cuvee from 50+-year-old vines, the 2006 Beaucastel Chateauneuf du Pape Vieilles Vignes white. This is a sensational wine, with notes of lychee, marmalade, and exotic fruits such as mango in addition to more classic notes such as poached pear and buttered brioche. The wine is full-bodied, unctuously textured, but not heavy or plodding. This is a masterpiece of white winemaking that is full-bodied, powerful, and should drink beautifully for 4-6 years before it heads into unknown territory. My guess is that this will rebound in about 12-15 years time and last for 25-30 years.
