(97-99 points) Deep garnet in hue, the wine shoots from glass with tobacco leaf, currants, spice box, cigar wrapper, blackberry and cassis. Elegant, fresh and vibrant, the wine is silky, long and precise. There is a cool spicy note that rides along with all the layers of soft, polished fruits on the mid-palate and in the finish. This is a refined vintage for COS. You find lower alcohol and the wine feels more energetic on the palate and in the finish, even though the pH is high at 3.9. Let it sleep for at least a decade before popping a cork. Produced from a blend of 62% Cabernet Sauvignon and 38% Merlot, 13.46 % ABV, the harvest took place September 10 to September 24.

(97-98 points) This is a very refined, polished Cos with superb finesse and length. Medium-to full-bodied, very fine and persistent. Really long with beautiful tannins. Rich, but fresh and linear. Yet, the alcohol is around 13.5%. 62% cabernet and 38% merlot.

(WA 96-98 points) The 2020 Cos d'Estournel is composed of 62% Cabernet Sauvignon and 38% Merlot. The harvest took place September 10–24 with a yield of 39 hectoliters per hectare. The alcohol weighs in at 13.46% with a pH of 3.9 and an IPT (total phenolic index) of 80. It is being aged in French oak barrels, 55% new. Deep purple-black in color, it pops with explosive scents of ripe red and black currants, black cherry preserves and black raspberries, followed by sparks of violets, wild sage, pencil lead and clove oil, with emerging hints of iron ore and damp soil. The medium-bodied palate has amazing elegance and grace contrasted by jaw-dropping energy, featuring a firm frame of finely grained tannins and just enough freshness, finishing with a whole firework display of mineral nuances. I love the way this Cos d'Estournel shimmies and shines—a unique vintage signature expressed so beautifully at this estate! - Lisa Perrotti-Brown

(96-98 points) Barrel Sample. Powerful, ripe fruits show exceptional quality and a velvety character that's allied to a ripe structure. With the freshness so typical of the vintage, the wine seems open and fruity but surprises with its density. ROGER VOSS

You need to take a little time to let the concentrated flavours seep out, this is a long hauler. The tannins build slowly but surely through the palate, sombre and serious right now, particularly for an estate that is known for its exuberance. The opulence is there if you give it time, and as the tannins elongate and relax, richer notes of bilberry fruits, toasted cedar, salted chocolate, turmeric and black pepper spice arrives. Harvest September 10 to 24. A 3.9pH is the highest since 2003, but any threat of low acidity is balanced by high tannins, and relatively low alcohol. A yield of 39hl/ha (43hl/ha in 2019).

(JD 95-97+ points) The Grand Vin 2020 Château Cos D'Estournel is based on 62% Cabernet Sauvignon and 38% Merlot that was brought up in 55% new French oak. An inky-hued, concentrated, yet flawlessly balanced wine, it has gorgeous cassis and dark currant fruits, medium to full-bodied richness, ripe, building tannins, and just a wonderful sense of purity and elegance backed up by ample concentration. It stays tight, focused, and seamless, and is a brilliant example of the vintage. The 2020 hit 13.4% natural alcohol with a pH of 3.9 and an IPT of 80.

(VN 94-96 points) The 2020 is a gorgeous wine from a very unusual year in which the Merlot is a bit more prominent in the blend than usual because of dehydration in the Cabernet. Even so, the 2020 is a wine of mid-weight finesse more than opulence. All the elements are impeccably balanced throughout. -- Antonio Galloni

A broad, rich, enticing wine, built on a core of exotic mulberry and loganberry notes laced with black tea, spices and incense. Rounded through the finish, with the fruit cruising through under a suave gloss of toast. A real crowd-pleaser, with a luxurious feel that makes this hard to lay off of now. Cabernet Sauvignon and Merlot. Drink now through 2038. — J.M.
