This shows beautiful aromas of flowers, raspberries and blackberries that follow through to a full body with ultra silky tannins and a long, long finish. It lasts for minutes. Best in 2018 or later.

A little tough now but a solid core of currants and blueberries. Full body, with chewy tannins and a bright, crisp acidity on the finish.

The Clos du Marquis demands some coaxing from the glass but it is worth persevering: blackberry, oyster shell, a hint of seaweed – a complex bouquet that entices you in. The palate is medium-bodied with fresh black fruit on the entry. It feels supple in the mouth, beautifully balanced towards the finish with dark cherries and plum lingering on the aftertaste. Excellent. Tasted November 2012.

Cropped at just 36.7hl/ha, the Clos du Marquis is a blend of 75% Cabernet Sauvignon, 17% Merlot and 8% Cabernet Franc raised in 37% new oak, offering 13.6% alcohol with a pH of 3.63. The nose is driven by the cedar-infused Cabernet, one of the most closed noses that I have encountered during primeur. The palate is medium-bodied with very fine, saturated tannins, a little fleshier that I was expecting given the percentage of Cabernet Sauvignon, but very harmonious on the finish that belies the structure underneath. Drink 2016- Tasted March 2011.

A graceful wine, with beautiful violet and raspberry aromas and flavors. Very fresh and pure, with the floral edge lingering through the finish. Long and supple. Tasted non-blind. —J.M.

(36.7hl/ha, 13.6%) [75CS/17M/8CF] Black purple; very minerally Cabernet Sauvignon to smell, with just a hint of herbal from the Cabernet Franc; lovely balance, elegant, vital, fresh, and with an almost delicately refined tannin; classic claret in flavour and style; very ripe red fruit to taste, flowing, fresh, surprisingly floral in the fineness of its fruit, a fragrance which covers the mouth and throat on the finish, and superb fragrant length. A really lovely Clos du Marquis; very classic style and proportions, the year notwithstanding; classy, complex and fine. Likely to be accessible relatively early. 2018-30+ [M.Schuster, Bordeaux Mar/Apr 2011 ]

With the alcohol hitting 13.6% in a blend of 75% Cabernet Sauvignon, 17% Merlot and 8% Cabernet Franc, this wine displays plenty of sweet kirsch, licorice and black currant fruit in a classy, seductive style, with medium to full body, soft but abundant tannins and a long finish. It does indeed possess the elegance and finesse of its bigger sibling, Leoville Las Cases. Drink it over the next 10-15 years. Drink: 2013 - 2028

Clos de Marquis is no longer a second wine, but rather one from a separate vineyard in the holdings of Leoville Las Cases. It should be thought of as a different entity, although the same winemaking team and philosophy are at play.

2010: Now essentially treated as a separate estate by Jean-Hubert Delon, and not as a second wine of Leoville Las Cases (whose second wine is now the newly introduced Le Petit Lion), Clos du Marquis has been a shrewd consumer’s purchase for almost two decades. Interestingly, the first vintage of Clos du Marquis was introduced in 1902! The 2010, which is an exceptional wine, was produced from the same parcel that always goes into this wine. A blend of 75% Cabernet Sauvignon, 17% Merlot and the rest Cabernet Franc, it is a relatively big wine at 13.6% natural alcohol, with loads of black cherries, black currants and crushed rocks in a medium to full-bodied format. Layered, intense, high-class and complex, this wine should drink nicely for 15 or more years.
