"Deep colour. Beautiful dark cherry cassis lead pencil aromas with cedar complexity. Generous supple yet structured with lovely dark fruits, viscosity, vanilla oak notes and plentiful chalky bitter notes. Superb graphite tannin finish with pure fruited length. Very elegant style but with classic undercarriage. Tannin plume. A very expressive wine. Tasted at Ch Cos d'Estournel."

"The beautiful 2016 Cos d'Estournel is one of the most polished, gracious young Cos d'Estournels I can remember tasting. Aromatic freshness and lift, along with a distinctly red fruit profile, are among the signatures. It will be interesting to see if this style of Cos - one in which concentration and textural richness are backed off - is the result of the vintage or an evolution in winemaking philosophy, or perhaps, as is most likely, a little bit of both."

"The 2016 Cos d'Estournel takes the 2016 baton and runs with it. A blend of 76% Cabernet Sauvignon, 23% Merlot and 1% Cabernet Franc that was picked between 26 September and 15 October at 45 hectoliters per hectare, this fabulous Saint Estèphe will be matured in 60% new oak. The alcohol level this year is 13.07%, which proprietor Michel Reybier reminded me is almost 1.5% lower than in 2010. This is clearly a more classically styled Cos d'Estournel that is completely different than say, the 2009 Cos d'Estournel and the more flamboyant, exotic wines in recent years. It actually bears more stylistic similarities to its neighbor Montrose. It is extremely detailed with blackberry and a touch of boysenberry, the fruit almost "creeping up" on you by stealth and then underneath, an undertow of minerals, wet limestone and even flint. The palate has astonishing: exquisite balance, perhaps the most precise and detailed Cos d'Estournel that I have encountered in many years of tasting at this address. It segues into a Pauillac-like second-half with veins of graphite strafing the black fruit, but what marks this Cos d'Estournel is the palpable energy and tension allied with an effortless nature. The persistence, the reverberation in the mouth is quite magnificent, perhaps even longer on my second visit to the property compared to the first. It really is a brilliant Cos d'Estournel that oozes class and sophistication, moreover, a wine that is going to give serious amounts of drinking pleasure over a very long period of time. Boom—and Cos drops the mic. Tasted twice, almost three weeks apart, with consistent notes."

"The finish is something else here. This is a wine that’s so powerful and tannic yet at the same time so polished and superb on the finish. Full-bodied, beautifully crafted and precise. This is a wine that really grabs your attention. The agility and power are more than impressive. Wow is the word."

"76% Cabernet Sauvignon, 23% Merlot, 1% Cabernet Franc. 26 September to 15 October. IPT 69. pH 3.66. Very similar analysis to 2015. 45 hl/ha yield, which they feel is best for vine balance now. Energy and raciness on the nose. Gentle and lifted. And then lots of tannins underneath. Fresh almost sandy tannins. Good energy and tea-leaf sensation. Excellent freshness. Long. Restrained. Elegant."

Saint -Estèphe, with 1,377 hectares under vine is the largest of the major Bordeaux appellations in the Medoc. Located in the most northern part of the Left Bank, on average, 585,000 cases of wine are produced each year. The soils see a rich mixture of rocks, clay, limestone and gravel that rests on the surface and of course below, deep in the terroir. Beneath the surface lies a complex blend of different soils, sub soils and terroir. Over the past several decades, the general trend in the Saint -Estèphe vineyards has been to add more Merlot, which has added a lot of softness to the tannins and the wines. Merlot works well in the appellation due to the large amount of clay found in the soils. in the appellation due to the large amount of clay found in the soils.
