Christian Balog beschreibt den Wein wie folgt:
Die Nase zeigt ein wenig Gewürzkiste, etwas Tabak und reife dunkle schwarzfricht, eine saftige rote Kirsche. Das Holz ist sehr behutsam ei gebunden bisher. Im Mund ist der Wein satt und klar auf der fruchtigen Seite, sehr feinkörnige Tannine, gute Balance, frisch im langen und vitalen Finale. Er überzeugt mit seiner in sich ruhenden Komplexität und Finesse. 94-95 Punkte
William Kelly zum Chateau Cos d Estournel 2021 Saint Estephe (April 2022):
The 2021 Cos d'Estournel is very promising, offering up rich aromas of dark berries, plums, exotic spices, loamy soil and rose petals, followed by a medium to full-bodied, deep and seamless palate that's impressively vibrant and concentrated, with powdery tannins, bright acids and a long, penetrating finish. Only 53% of the production made it into the grand vin, and the blend is 64% Cabernet Sauvignon, 30% Merlot, 4% Cabernet Franc and 2% Petit Verdot. Technical director Dominique Arangoïts reports that Cos was spared by frost and coulure at flowering, harvesting between September 23 and October 4, and fermenting a touch hotter than has been the case in recent years, at around 28-29 degrees Celsius.
Jeb DUNNUCK (Jeb Dunnuck) : 92-94 / 100
The Grand Vin 2021 Château Cos D'Estournel is 64% Cabernet Sauvignon, 30% Merlot, 4% Cabernet Franc, and 2% Petit Verdot that saw 55% new French oak. It offers a beautiful, elegant, medium-bodied style that carries plenty of pure cassis and almost blue fruits as well as graphite, spicy wood, and hints of tobacco. The tannins are polished, and it has terrific balance, good density, and outstanding length. It's certainly in the more focused, elegant, narrow style of the vintage, but it's beautiful.
James Suckling im Mai 2022
A firm red with solid, compact tannins. Medium to full body with plenty of blackcurrant, pencil-lead and graphite character. Compact and structured throughout, with a firm finish. Linear and muscular tannins at the end that are very formed and curated. It will be interesting to see how this one evolves. 64% cabernet sauvignon, 30% merlot, 4% cabernet franc and 2% petit verdot.
The Wine Cellar Insider (Jeff Leve) : 95-97 / 100
Earthy, spicy, black raspberries, blackberries, flowers, and black currants create the nose and the core of its medium/full-bodied palate. Soft, silky, fresh and polished, there is a nice sweetness and refined edge to the fruit on the palate, finishing with layers of vibrant, peppery, tea-stained, black currants with a gentle hint of herbs on the backend. The wine was made from blending 64% Cabernet Sauvignon, 30% Merlot, 1% Petit Verdot and 1% Cabernet Franc,13% alcohol, pH of 3.7. The yields were 35 hectoliters per hectare. The harvest took place September 23 to October 7. The Grand Vin was produced from 50% of the harvest. The wine is going to approachable early in its life. Drink from 2025-2055.
