99+ Robert Parker - Robert Parker's Wine Advocate

"The virtually perfect (probably Domaine du Caillou’s greatest wine since their 2001 example) 2010 Chateauneuf du Pape Reserve Le Clos du Caillou is a blend of 60% Grenache and 40% Mourvedre aged completely in 600-liter demi-muids, of which some are new. A dense purple color is accompanied by a stunning nose of lead pencil shavings, barbecue smoke, black currant jam, raspberries and blueberries. Full-bodied and exceptionally pure, powerful and elegant, this stunning wine needs 2-4 years of cellaring and should keep for 20-25."

98 Jeb Dunnuck - The Rhone Report

"Possessing an inky purple color as well as spectacular purity, freshness, and an understated elegance about it, the 2010 Le Clos du Caillou Reserve is a blend of 60% Grenache and 40% Mourvedre - all from the sandy soils of the La Guigasse lieu-dit – that is aged 18 months in 1, 2, and 3-year-old demi-muids. It exudes class and finesse with fresh blackberry, cassis, melted licorice, graphite, herbs de Provence, and hints of crushed flowers all showing on the nose. Incredibly rich, full-bodied, and powerful on the palate, yet also fresh and elegant, with a seamless texture, perfect balance, and very fine tannin that emerge on the finish, this knockout Châteauneuf-du-Pape needs a solid 7-8 years of bottle age, and will age effortlessly for 25+ years."
