Robert Parker's Wine Advocate (95-97 points):
"The deeper, richer 2015 Châteauneuf du Pape Cuvee Reserve des Deux Freres is 100% Grenache that’s aging in 60% new and once-used barrels. Inky colored, full-bodied, massively concentrated and layered, it has a modern slant, yet still screams Southern Rhône with its cassis, caramelized dark fruits, roasted garrigue and licorice aromas and flavors. Like the Mon Aïeul, it’s elegant, impeccably balanced, and has sweet tannin. Give bottles 4-6 years in the cellar and drink over the following 10-15 years."

"The 2015 Châteauneuf-du-Pape Reserve des Deux Freres is more backward and structured, yet offers serious amounts of darker fruits, currants, smoked herbs, roasted meats and licorice aromas and flavors. Like the Cuvée Mon Aïeul, this cuvée sees plenty of stems, yet they’re beautifully integrated and balanced by masses of fruit. Full-bodied, concentrated, incredibly well textured and balanced, with bright acidity, forget bottles for 4-5 years and enjoy over the following 15-20 years."
