Majestic, intense, full-bodied and tannic, Cos d’Estournel is considered the leading wine of St Estèphe. Highly tannic in its youth, over time it develops much much like the great wines of adjoining Pauillac.
The wine is typically a blend of 60% Cabernet Sauvignon, 38% Merlot and 2% Cabernet Franc, consistently displaying immense power and evident breed.
Deep colour. Dark berry cassis, pastille like aromas with herb garden ginger spice notes. Fresh supple inky wine with cassis fruit, fine muscular but precise tannins. Finishes firm but the fruit has outstanding persistency. Al dente finish. Lovely precision, muscular drive and mineral length. 13.4% alcohol.

This shows what great selection did in the northern Mêdoc. Big surprise. Really excellent. Full body, chewy and rich tannins and loads of ripe fruit. Black currants, blueberries. It has hot and ripe tannins yet cool fruit.

Super aromas of nutmeg, cloves and dried flowers with plums and blackberries. Subtle yet so complex. Full-bodied, tight and integrated with ultra-fine tannins and a beautiful finish. Lasts for minutes. Very, very Cos. Harmony. Texturally marvellous. Drink in 2024.

The 2015 Cos d'Estournel is composed of 75% Cabernet Sauvignon, 23.5% Merlot and 1.5% Cabernet Franc. Deep garnet-purple in color, it offers up black currants, spice cake, warm cherries and plum preserves with touches of chargrill and forest floor. Medium-bodied and very firm with ripe, grainy tannins, it has a good core of earthy fruit, finishing with loads of layers and freshness.

Composed of 76% Cabernet Sauvignon, 23.5% Merlot and 1.5% Cabernet Franc, the deep garnet-purple colored 2015 Cos d'Estournel is muted at this very young stage. The nose offers fleeting glimpses at provocative cherry tart, chocolate mint, baked redcurrants, warm cassis and wild blueberry scents plus suggestions of lilacs, cinnamon stick and Indian spices. Medium to full-bodied, the palate absolutely explodes with vibrant red and black fruit bursts and tons of exotic spice accents, framed by super ripe, super firm tannins and a lovely line of freshness, finishing very long.

The 2015 Cos d'Estournel is a blend of 75% Cabernet Sauvignon, 23.5% Merlot and 1.5% Cabernet Franc that was picked between 17 September and 5 October at 44 hl/ha. It is being matured in 65% new oak, less than in recent years due to the tannin (IPT is 71). Deeper in color than the 2015 Pagodes, it has a very pure bouquet with tightly knitted blackberry, blueberry and violet scents, perhaps just a little Margaux-like in style. The palate is medium-bodied with supple tannin, well-judged acidity and harmonious in the mouth. What it does not quite deliver is the complexity of a top-tier Cos d'Estournel or the peacock's tail of flavors on the finish, which feels linear and conservative compared to its peers in more southerly appellations. You feel as if the vintage put a tight leash on this Saint Estèphe grandee. There is pedigree in this Grand Vin for sure and it is bound to give up to 20 years of pleasure.

The 2015 Cos d’Estournel is a little recalcitrant and broody on the nose, like it always has been from bottle, unfolding gradually with enticing, quite intense blackberry, pencil box and subtle tobacco scents. The medium-bodied palate immediately impresses by its volume and depth, the new oak neatly embroidered with layers of tightly coiled tobacco and graphite infused fruit whose veins of earthiness betray its origins. Whilst it does not quite deliver the flair and untrammeled ambition of the 2016, this is a very impressive forerunner. Wise owls will afford it a decade bottle age before reaching for the corkscrew. Tasted at the Cos d’Estournel vertical in London.

A wine of cool sophistication and polish, the 2015 Cos d'Estournel is endowed with striking length and overall balance. Silky tannins support a core of graphite, smoke, licorice, incense, tar and dark spice. The 2015 is perhaps not as aromatically nuanced or expressive as in the very best years (although that may develop in time), but it offers terrific persistence through to the finish. Finesse and nuance are the key signatures in the 2015 Cos. Only 39% of the crop went into the Grand Vin, as opposed to the more typical 50% or so.

Easily one of the most successful wine in Saint Estèphe in 2015, Cos d'Estournel is just gorgeous. Elements of exoticism appear on the bouquet, followed by generous black cherry, smoke, leather, licorice, menthol and mocha. Naturally, it will be many years before the 2015 is ready to offer a truly complete drinking experience, but it is superb even in the early going. The 2015 was bottled in July 2017.

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.
