Tasted at Bordeaux Index's annual 10-Year On tasting in London and then blind at Farr Vintners horizontal, the 2006 Château Léoville Las-Cases has a very complex bouquet with heady scents of blackcurrant, kirsch, crushed violets, rock salt and just a hint of cassis. It is backward and can barely contain its energy. The palate is medium-bodied with fine tannin, very symmetrical and poised, a fine line of acidity interwoven through the black fruit, touches of citrus fruit developing towards the poised and tensile finish. This is a beautiful wine from Jean-Hubert Delon, but it needs several years in bottle. Tasted April 2016.

Offers a pure nose of crushed raspberry and violet, with aniseed. Full-bodied, with beautiful, well-integrated tannins and a long, polished texture to the finish. Very beautiful. Harmonious and structured. Best after 2015.

While the aromas are tight and firm, once it is in the mouth, this wine just explodes. The tannins are dark, almost impenetrable, dry and dense. These tannins are a layer over the fruit that just piles up with ripe blackberry juice, an edge of blueberry. The soft sweetness of this range of flavors continues on the finish, pitted against the tannins.

Aromas of blackberries, black olives, raspberries, iodine and asphalt follow through to a medium to full body with a tight, layered palate and a juicy finish. Hints of iodine at the end. Some licorice, too. Drink now.

Bright, full ruby. Brooding aromas of cassis, black cherry, minerals, bitter chocolate, shoe polish and violet; more Pauillac than Saint-Julien on the nose. Then rich, lush and powerful, with impressive fullness and volume. As full and sweet as this is, there's no impression of excess weight and the back end shows a distinctly austere quality, even if the serious tannins are nicely buffered by the wine's rich middle. Really stains the palate with flavor on the aftertaste. Wonderfully ripe cabernet sauvignon here; in fact, most of the cab franc in 2006 was declassified into the Clos du Marquis.
