Wine Advocate: 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.

Vinous: 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.
