"One of the greatest young wines I have ever tasted, the monumental 2009 Cos D'Estournel has lived up to its pre-bottling potential. A remarkable effort from the winemaking guru Jean-Guillaume Prats and owner Michel Reybier, this blend of 65% Cabernet Sauvignon and the rest Merlot (33%) and a touch of Cabernet Franc (2%) was cropped at 33 hectoliters per hectare. It boasts an inky/black/purple color along with an extraordinary bouquet of white flowers interwoven with blackberry and blueberry liqueur, incense, charcoal and graphite. The wine hits the palate with extraordinary purity, balance and intensity as well as perfect equilibrium, and a seamless integration of tannin, acidity, wood and alcohol. An iconic wine as well as a remarkable achievement, it is the greatest Cos d'Estournel ever produced. It is approachable enough at present that one could appreciate it with several hours of decanting, but it will not hit its prime for a decade, and should age effortlessly for a half a century. Drink 2022-2072."

"Blended of 65% Cabernet Sauvignon, 33% Merlot and 2% Cabernet Franc, the deep garnet-purple colored 2009 Cos d'Estournel takes a little coaxing to encourage the full array of exotic spices and decadent black fruits to emerge here: crème de cassis, baked plums, blueberry compote and Black Forest cake intermingled with star anise, fenugreek, cumin seed and Sichuan pepper plus wafts of menthol, violets and smoked meats. Wow—the full-bodied palate bursts with powerful, hedonic black fruit preserves and spices, completely coating the mouth with decadent fruits that are perfectly framed by very firm yet very ripe, grainy tannins and bold freshness, finishing with a veritable firework display of floral, spice and red fruit notes. Just stunning."

"What a fabulous nose of currants, raspberries and Indian spices. Nutmeg and clover. Full-bodied, with an amazing precision and superb compacted fruit. Endless. Laser guided. Shows such intensity. Decadent and rich and changing all the time. Mystical wine. Dense, yet agile. More refined than when I tasted it in November in Hong Kong. Try in 2018."
