Rich yet firmly structured this is a very classic St.-Julien that's generous and polished with so much energy driving the long plush finish. Delicious now, but should hold for many years. (Horizontal Tasting, London, 2019) - Stuart Pigott, jamessuckling.com, March 2019

Now positioned as a totally separate vineyard and a real clos (enclosed walled vineyard), this blend of 70% Cabernet Sauvignon, 20% Merlot and the rest Cabernet Franc and Petit Verdot from Jean-Hubert Delon is a beauty. Creme de cassis notes intermixed with some vanillin, crushed rock and spring flowers jump from the glass. Full-bodied and powerful (nearly 14% natural alcohol), this is a generously endowed, rich wine that was first made in 1902. The 2009 should drink well for 20-25 years. Readers need to think of it as a true classified growth, although technically it is not.

Clos du Marquis is being positioned by Jean-Hubert Delon as a separate single vineyard wine rather than Leoville Las Cases' second wine. The logic is simple. It has come from the same vineyard for over twenty years, and is not a true second wine in the sense that it is not made from Las Cases' discarded cuvees. The 2009 Clos du Marquis (70% Cabernet Sauvignon, 20% Merlot, and the rest Cabernet Franc and Petit Verdot) came in at 13.75% alcohol. It exhibits a deep ruby/purple hue along with sweet notes of creme de cassis, great purity, a full-bodied mouthfeel, and terrific texture as well as length. It should evolve for 20-25 years. (Tasted once.) (91-93)

Tasted at the château. A blend of 70% Cabernet Sauvignon, 20% Merlot, 8% Cabernet Franc and 2% Petit Verdot with 7.6% vin de presse, delivering 13.75% alcohol and a pH of 3.70. The Clos du Marquis has a sexy, quite opulent and very pure bouquet with lascivious red-berried fruits, vanilla, blueberry and a touch of cedar. The palate has a seamless entry, very focused and beautifully balanced, glides across that palate, filigree tannins, sensuous and silky towards the finish. Very alluring, but perhaps just missing a little delineation and edginess towards the finish. Still, this Clos du Marquis is as impressive as usual. Tasted March 2010.

[70CS/20M/8CF/2PV] Dense, mineral, lightly oak-cedar nose; nicely balanced middleweight, fresh, finely tannic, with a generous, crisp, lightly gravelly red fruit flavour; a nice fat, and 'velvetty' 09 texture, and good, light length, but perhaps lacking a bit of scope and complexity in the context of the vintage? 2014-24
