Cos-d’Estournel 2020

Outer quote mark Based on 62% Cabernet Sauvignon and 38% Merlot, the deep purple-hued 2020 Château Cos D'Estournel has, dare I say, an almost Lafite-like sense of elegance and class, offering gorgeous cassis and darker currants fruits as well as tobacco, lead pencil, acacia flowers, and graphite. Hitting 13.46 alcohol, with a pH of 3.9 and an IPT of 80, this flawless, full-bodied, incredibly elegant Saint-Estèphe has silky tannins, perfect balance, and a great, great finish. It will need a decade of cellaring to hit its prime drink window. Of the trilogy of 2018, 2019, and 2020, it's clearly my favorite (that’s splitting hairs), with a similarity to the 2016, and will most likely merit another point at maturity.

Cos-d’Estournel 2018

The richness and beauty of this wine is impressive with blackcurrant, cherry, berry and fresh cloves. The fruit is so pure here. Full-bodied with tannins that are so integrated and refined that you don’t feel them, yet they are there! Very creamy and layered with great length and beauty. It turns to tar and licorice at the finish. Tight now, but the texture is special. Try after 2027.

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.

Love tasting this wine. You almost want to drink it for its harmony and balance. Full-bodied and so complete with cloves, spices, dark berries and hints of chocolate. Wonderful integration on the finish.
