The grand vin 2016 Cos d'Estournel checks in as 76% Cabernet Sauvignon, 23% Merlot, and 1% Cabernet Franc that saw 70% new French oak. One of the more seamless, pure, elegant versions of this cuvée out there, it boasts a saturated purple color as well as a monster nose of pure crème de cassis, gravelly, rocky minerality, tobacco leaf, crushed violets, and lead pencil shavings. One of those “iron fists in a velvet glove” wines, with full-bodied richness and beautiful structure that’s covered by thrilling levels of fruit and texture, it stays tight, compact, and incredibly focused on the palate. It’s already brilliant given its purity of fruit and balance, but it deserves a decade of bottle age and will keep for 4-5 decades. - jebdunnuck.com, February 2019

This is a little tight right now, as are so many of the 2016s. The fruit is deep, dark and concentrated, with fierce tannins that will take a long time to come around but will age well. There's no question that this is a monumental Cos, with the walls of slate ready to be scaled, joined by a rosemary and black olive tang, juicy liquorice root and lashings of cassis. I tasted this wine both en primeur and again during a vertical at the property in July, and have felt thrilled to recommend it each time. Aymeric de Gironde was still the director at the time, before leaving in 2017. - decanter.com, Jane Anson, October 2018

The 2016 Cos d'Estournel is polished, silky and gracious, just as it was from barrel. In this vintage, the Grand Vin is especially refined. The dark red cherry, plum, new leather, licorice, cedar, mocha and spice notes are all beautifully delineated. To be sure, the 2016 represents a decidedly laid-back style within the context of recent vintages. I can't wait to see how it ages. - vinous.com, January 2019

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. Very dense and dark with just a hint of the perfume and exotic fruit which lurks beneath. Broad mouthfeel, velvety and rich but supple and dense. Tannins are quite pronounced and unlike many others, this feels a long way from being ready to enjoy. It will certainly make old bones with its balance of acidity and tannic power. - April 2017

Energy and raciness on the nose. Gentle and lifted. And then lots of tannins underneath. Fresh almost sandy tannins. Good energy and tea-leaf sensation. Excellent freshness. Long. Restrained. Elegant. Drink 2025-2042. - jancisrobinson.com, April 2017

You could lose count if you were trying to number all the layers of velvet drenched, powerful, lifted, sweet, fresh deep red fruits here. The wine offers incredible levels of concentration along with precision, purity, power and elegance. But to take all this in at its peak, patience is required as you will need at least 12 years or so before this really starts shining. But it is going to be worth the wait. Tasted Sept 2019

The 2016 Cos d'Estournel is blended of 76% Cabernet Sauvignon, 23% Merlot and 1% Cabernet Franc aged in 65% new and 35% two-year-old French oak for 15 months. Bottled in July 2018, it is deep garnet-purple colored and starts off a little closed and reticent, opening out slowly and seductively to reveal beautiful lilacs, rose hip tea, crushed stones and camphor nuances over a core of crème de cassis, kirsch, wild blueberries and mocha plus wafts of incense and wood smoke. The palate is simply electric, charged with an energy and depth of flavors that seem to defy the elegance and ethereal nature of its medium-bodied weight, featuring super ripe, densely pixelated tannins that firmly frame the myriad of fruit and floral sparks, finishing with epic length. Just. Magic. LPB

The 2016 Cos d’Estournel was a bona fide showstopper out of barrel, the best that I had encountered in over 20 years of visiting the estate during en primeur, so my expectations were piled high when I returned to find out how it performs in bottle. Deep, almost opaque in color, it sports a very intense but broody bouquet with fathomless deep black fruit tinged with blueberry and violet. The aromas almost seem to envelop the senses. The palate is medium-bodied with ultra-fine tannin that I have never witnessed in any other vintage of Cos d’Estournel. There is a beguiling symmetry to this Saint-Estèphe, as well as unerring mineralité. The persistent, tobacco-tinged finish can be felt 60 second after the wine has departed. This is a monumental, benchmark Cos d’Estournel that will give not years but decades of pleasure, though I suspect it will close down for a period in its youth, hence my drinking window. 13.07% alcohol.

This is muscular yet so well defined and toned. Full-bodied with deep and dense fruit on the palate, yet powerful and rich at the same time. So much sandalwood and blackberry character. Chewy and rich at the finish. This is a warm and generous wine, but the alcohol is just over 13 degrees. Not that high. Love the finish. Extravagant. Magical. Try from 2025. - February 2019
