Composed of 66% Cabernet Sauvignon, 32% Merlot, 1% Petit Verdot and 1% Cabernet Franc, yields for the grand vin in 2017 were 43 hectoliters per hectare, and it was aged in 60% new oak. It came in at an alcohol of 13% and an IPT of 68. Deep garnet-purple colored, the 2017 Cos d'Estournel needs a little coaxing to unfurl, revealing beautiful expressions of preserved plums, boysenberries, blackcurrant pastilles and wild blueberries with hints of Indian spices, menthol, lilacs and mossy tree bark plus a compelling suggestion of iron ore. Medium to full-bodied, the palate has a solid backbone of firm, grainy tannins and well-knit freshness supporting the tightly wound blue and black fruits layers, finishing long and fragrant. This wine will need a good 5-7 years in bottle before it begins to blossom and should go on for at least another 40 years. I expect this wine to be a blockbuster of a head-turner when I come back and taste it at 10 years of age! LPB

Quite the bottle here! Spices, such as nutmeg and cinnamon, as well as dried meat and plums with cedar and sandalwood. Full body. Deep and dense in the center palate and a long, long finish. Shows finesse and tightness. Very polished tannins. Long and ethereal.

Quite dark in color, the wine is full bodied, concentrated, lushly textured and offers a serious depth of flavor. Power and elegance make a perfect pairing here. The glycerin filled finish coats your palate, leaving you with a mélange of dark fruits that keep going for almost 50 seconds. The wine was made from blending 66% Cabernet Sauvignon, 32% Merlot, 1% Petit Verdot and 1% Cabernet Franc, reaching 13% ABV with a pH of 3.7. The harvest took place September 12 to September 30 and the Grand Vin was made from only 40% of the harvest. Tasted April 2018

The Indian-inspired 19th century architecture at Château Cos d’Estournel (and its 100-year-old vines) sits in stark contrast to the modern winery, with its 100% gravity-fed cellar and shiny isothermal vats. The 2017 is a blend of 66% Cabernet Sauvignon, 32% Merlot, 1% Cabernet Franc and 1% Petit Verdot, aged in 60% new oak. Georgie Hindle: Beautifully floral notes on the nose. Just so appealing and inviting. Rich and quite sensuous on the palate – texture of crushed velvet, mineral, with fleshy weight. Mouthfilling, on the richer, plusher side, lots going on. Vincenzo Arnese: A rich, developed nose, showing ripe blackcurrant, raisins and sultanas, with a hint of black tea. Rich and poised. Tannins are powerful and will integrate better with time, but the potential is astonishing. Andy Howard MW: Deep, impenetrable colour. Soft, voluptuous palate with ripe, dark fruits, an exotic edge, fine tannins and fresh acidity to finish. Has concentration and weight for further development. Drinking Window: 2023 - 2048

The 2017 Cos d’Estournel showed extremely well from barrel and likewise in bottle, continuing this estate’s strong run of form since the 2014 vintage. You instantaneously fall in love with the nose that bursts forth with blackberry, raspberry coulis, crushed stone, iodine and pressed iris petal. The 60% new oak is beautifully integrated. Quintessentially Cos d’Estournel. The palate is medium-bodied with supple black fruit laced with black truffle and graphite, quite Pauillac-like in style, which is no surprise given its location. This is very focused and perhaps understated compared to the 2016, yet its freshness and vivacity are undeniable. "Streamlined, cool and linear" I wrote at en primeur... I have no reason to alter that sentiment. www.vinous.com

A bold, dramatic wine, the 2017 Cos d'Estournel is seriously impressive today. Time in barrel has done wonders for the 2017, a wine that has really gained depth in élevage. Black cherry, chocolate, spice, new leather, licorice, smoke and incense infuse the 2017 with tons of character, with the 60% new oak very well judged. In 2017, Cos has a level of textural resonance that eludes many Saint-Estèphes. The blend is 66% Cabernet Sauvignon, 32% Merlot, 1% Petit Verdot and 1% Cabernet Franc.

The grand vin 2017 Chateau Cos D'Estournel checks in as 66% Cabernet Sauvignon, 32% Merlot, and 1% each of Cabernet Franc and Petit Verdot brought up in 60% new French oak. It's a classic 2017 that shows the straight, very classic style of the vintage with its medium to full body, ripe, present tannins, and solid spine of acidity. Beautiful cassis, green tobacco, graphite, and cedar pencil notes all emerge from the glass, and as with the Pagodes, it's still tight and reserved on the palate. Reminding me of the 1996 with its classic, balanced style, give bottles 5-7 years and enjoy over the following two decades.

With its exotic architecture and distinctive, powerful style, Cos d'Estournel is one of the most famous and sought-after Bordeaux year in, year out. Rich, complex, Cabernet-driven wine with an attractive balance of blackcurrant fruit, leaf and a light herby character. Mineral and interest. Rich, sweet fruit with good concentration and power, a firm, full tannic structure and a real sense of restrained presence. Polished and correct but with real energy and no litte drive and style. - April 2018

Inky with black core and purple rim. Dark-fruited and lightly charry to give a savoury/fruit complexity. Extremely pure cassis. A little more chewy than the Pagodes but still remarkably silky, with clarity, precision and length but without excess richness. Deep and long. Amazing balance already. Great precision, helped by a decade of experience in the new chai, says technical director Dominique Arangoits. Opens in the glass to reveal a hint of something floral. Plenty of depth but no excess weight, and modest alcohol. - Julia Harding, jancisrobinson.com, April 2018
