This is a bird of a different feather, with a ripe, sleek, and very polished feel as creamed loganberry, plum and boysenberry flavors spill forth, flanked for support by singed alder and incense notes, while black tea and savory threads curl around the finish. Long, showy and lovely. Cabernet Sauvignon, Merlot, Cabernet Franc and Petit Verdot. Best from 2024 through 2038. -Wine Spectator
The 2018 Cos d'Estournel is a blend of 74% Cabernet Sauvignon, 23% Merlot, 2% Petit Verdot and 1% Cabernet Franc, aged in 50% new oak barriques. The alcohol weighs in at just over 14.5%. Sporting a deep purple-black color, it needs a lot of swirling to begin to unlock a powerful nose of crème de cassis, stewed plums, wild blueberries and chocolate-covered cherries, followed by nuances of Sichuan pepper, star anise, tree and clove oil, plus a waft of charcoal. The full-bodied palate is densely packed with taut, muscular black fruits and earthy layers, framed by super firm, ripe, grainy tannin's and seamless freshness, finishing very long and wonderfully earthy. A very impressive behemoth, this is going to need a good seven to 10 years to truly show its stuff and should drink for a good 40 years and beyond. -Lisa Perrotti-Brown, Wine Advocate
The 2018 Cos d'Estournel is a racy, powerful Saint-Estèphe that is going to need quite a bit of time to find its center. Today, it is tightly wound, but all the energy is there. Lush and extravagantly ripe, the 2018 possesses tremendous depth and plenty of energy to back it all up. Here, too, I found the wine a bit more expressive and giving en primeur. -Antonio Galloni, Vinous
