The 2018 Cos d'Estournel is a blend of 74% Cabernet Sauvignon, 23% Merlot, 2% Petit Verdot and 1% Cabernet Franc, aged in 50% new oak barriques. The alcohol weighs in at just over 14.5%. Sporting a deep purple-black color, it needs a lot of swirling to begin to unlock a powerful nose of crème de cassis, stewed plums, wild blueberries and chocolate-covered cherries, followed by nuances of Sichuan pepper, star anise, tree and clove oil, plus a waft of charcoal. The full-bodied palate is densely packed with taut, muscular black fruits and earthy layers, framed by super firm, ripe, grainy tannins and seamless freshness, finishing very long and wonderfully earthy. A very impressive behemoth, this is going to need a good seven to 10 years to truly show its stuff and should drink for a good 40 years and beyond.

An incredible wine from this estate that's as good as anything in the vintage, the 2018 Château Cos D'Estournel checks in as 74% Cabernet Sauvignon, 23% Merlot, 2% Cabernet Franc, and 1% Petit Verdot that was brought up in 50% new French oak. While some 2018s are going to offer pleasure right out of the gate, this isn't one of them, but rather it's a backward, tannic powerhouse of a wine that has flawless balance as well as a level of purity that's off the charts. Thrilling crème de cassis fruit, notes of lead pencil, damp earth, cedarwood, violets, and acacia flowers, full-bodied richness, masses of ultra-fine tannins, and a great, great finish all make for a legendary Saint-Estèphe that will need a good decade of bottle age yet evolve for 50 years or more. If you are tempted to try a bottle in its youth, it needs lots of air.

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.

The 2018 Cos d'Estournel is a racy, powerful Saint-Estèphe that is going to need quite a bit of time to find its center. Today, it is tightly wound, but all the energy is there. Lush and extravagantly ripe, the 2018 possesses tremendous depth and plenty of energy to back it all up. Here, too, I found the wine a bit more expressive and giving en primeur.

Just a stunning bottle of wine, everything is rocking here. Deep and dark in color, the nose pops with flowers, licorice, 5 spice, currants, blackberries, orange rind, smoke and cigar wrapper. Full-bodied, elegant, long, deep, rich and pure, the vibrancy in the fruit keeps the seemingly-endless, expansive finish on the tip of your palate. Blended from 74% Cabernet Sauvignon, 23% Merlot, 2% Cabernet Franc and 1% Petit Verdot, the wine comes in at 14.5%. Much less wine was made this year as yields were only 30 hectoliters per hectare.

A little closed on the nose, and also on the attack. There is a wall of tannin here but backed up by voluptuously ripe fruits that major on damson and fig, overlaid with cinnamon and saffron spices. Lilting acidity through the finish keeps a sense of momentum. This is powerful with ambition, and it carries it off perfectly. 65% of production went into the grand vin. 1% Petit Verdot makes up the blend, and the wine was aged in 50% new oak (a little lower than the usual 60%).

The 2018 Cos d’Estournel showed a lot of promise when I tasted it from barrel. Now in bottle and given a 2–3-hour decant, it has a gorgeous and disarmingly pure bouquet, slightly high-toned with iodine scents infusing the lush blackberry and boysenberry scents. The oak is seamlessly integrated. The palate is fresh and crisp on the entry, delivering silky-smooth tannins, perfect acidity and a sense of harmony than is very persuasive. I cannot recall a Cos d’Estournel in recent years with such fine tannins. It gently fans out toward the finish while retaining superb precision, completing what is a beautifully crafted Cos d’Estournel with a long future ahead.

Rich and intense on the nose with spice and black fruit. Some complexity showing already here. Hugely structured and powerful with a massive, fresh, intense mid palate which drives into the finish which is long and layered with fine minerality. - April 2019

Black core with narrow purple rim. Intense black fruit with just a hint of charry oak. Smells sweet and ripe but pure and fresh-fruited too. Glorious Cabernet here. Deep, chewy and rich on the palate, firm velvet texture, incredibly moreish and so fresh, as much from the tannins as from the acidity. Leaves your mouth clean with dark, savoury, rocky length. Very precise winemaking. I love those dry clean-tasting tannins on the finish.Julia Harding, jancisrobinson.com, April 2019
