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! Due to its proximity to the Gironde estuary, none of the vines were impacted by frost in 2017 at Cos d’Estournel. Flowering took place on May 22, which was exceedingly early. In June, there were early signs of water stress, and the vines were slowing down and sluggish, according to technical director Dominique Arangoïts. But the vines at this vineyard are now coming in at an average age of 55 years old, which suggests they are capable of managing a bit of water stress. Thankfully, by the end of June, there was enough rain to reinvigorate the vines. This hydric stress appears to have equated to the formation of relatively small, thick-skinned berries in 2017. Thanks to the early flowering, it was an early start to the harvest: September 12. Harvest continued through until the end of the month.

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. Try after 2023.

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.
