Easily the greatest example from this château that I've tasted, the 2018 Château Calon Ségur checks in as 65% Cabernet Sauvignon, 17% Merlot, 15% Cabernet Franc, and the balance Petit Verdot aged 20 months in new French oak. This dense purple-hued beauty boasts a stunning nose of blackcurrants, crème de cassis, tobacco, baking spices, chocolate, and cedarwood. With full-bodied richness, a layered, multi-dimensional texture, gorgeous tannins, and one seriously long finish, it hits that palate with 15% alcohol, yet you wouldn't know it by tasting it, and the wine is perfectly balanced, has incredible purity of fruit, and stays fresh and lively, with a clean finish. This magical Saint-Estèphe can be drunk any time over the coming 20+ years.

The 2018 Calon-Ségur is blended of 65% Cabernet Sauvignon, 17% Merlot, 15% Cabernet Franc and 3% Petit Verdot (14.9% alcohol). It is anticipated to age for 20 months in barriques, 100% new. Deep garnet-purple colored, it needs just a little coaxing before it reveals seductive notes of baked cherries, warm cassis, licorice and smoked meats with nuances of hoisin, camphor, Chinese five spice and dried roses with a waft of cardamom. Full-bodied and completely packed with concentrated black fruit and spice layers, it has a firm frame of grainy tannins and a wicked backbone of freshness giving an energetic lift to the very long finish. There's lots of brightness coming from the Cabernet Franc component in here, but it is nonetheless a decadent expression.

Aromas of redcurrants and plums with blueberries and black licorice, following through to a full body that’s so refined and polished, the tannins integrated wonderfully into the fruit. Fresh, linear and persistent. Real clarity and purity to this. Try after 2025.

Wine Enthusiast : 97
This is a dense, generous wine. Swathes of black fruits are packed with concentrated tannins. Its power is palpable, as is its luxuriously rich future. The wine will take plenty of aging, so don’t drink before 2027. Cellar Selection

Wine Spectator : 95
Ripe, fresh and well-defined from start to finish, this lets cassis and dark plum notes race through, carried by a graphite edge and backed with dark tobacco, warm earth and chestnut accents on the finish. Has serious grip and drive. Cabernet Sauvignon, Merlot, Cabernet Franc and Petit Verdot. Best from 2024 through 2038.

Decanter : 94
Rose petal, cinnamon and cedar. An exotic feel overall held in by firm tannins that are welcome in the sense of the restraint that they add. Chocolate and coffee abound along with cassis fruits. I get the same impression as I did during en primeur - that this is a slightly atypical Calon-Ségur in its concentration and character, even though it has a seductive appeal.
