His cousin's daughter (and granddaughter of Clarence Dillon) Joan Dillon, then Princesse Charles de Luxembourg and later Duchesse de Mouchy, replaced him. In 1976, the 1970 vintage of Haut-Brion ranked fourth among the ten French and California red wines in the historic "Judgment of Paris" wine competition. The fierce competition that had existed between Haut-Brion and Château La Mission Haut-Brion over several years, which rose to a peak in the 1970s and early 1980s, ended when Domaine Clarence Dillon acquired La Mission in 1983. From the 2007 vintage, in connection with the 75th anniversary of Dillon family ownership, the red second wine Château Bahans Haut-Brion was released under the new name Le Clarence de Haut-Brion. The name Château Bahans Haut-Brion had been in use for at least a century, and over a period it was sold without a declared vintage. Starting with the 2009 vintage, the white second wine Les Plantiers du Haut-Brion was renamed La Clarté de Haut-Brion. Manager Jean-Bernard Delmas retired in 2003, and was succeeded by his son Jean-Philippe Delmas. Prince Robert of Luxembourg (son of Prince Charles of Luxembourg) who has acted as an administrator at Haut-Brion since the age of 18, became in 2008 Président Directeur Général of Domaine Clarence Dillon. Production Château Haut-Brion devotes to red grape varieties, with a distribution of 45.4% Merlot, 43.9% Cabernet Sauvignon, 9.7% Cabernet Franc and 1% Petit Verdot, and to white grape varieties, distributed with 52.6% Sémillon and 47.4% Sauvignon blanc. The vineyards are elevated, up to 27 meters, somewhat above the Bordeaux norm. The soil consists of Günzian gravel and some parcels have high contents of clay. All the vineyards are located in a cluster near the château itself and on the other side of the main road. The selection of optimum rootstocks and clones has been a large task at Château Haut-Brion, pioneered by Jean-Bernard Delmas, which has greatly contributed to the quality of the plant material in the vineyard. The long-term aim has been to lower yields, not by green-harvesting but by ensuring healthy and balanced vines. The average age of the vines is approximately 35 years with the oldest parcels dating back to the 1930s, planted with an average vine density of 8000 vines/ha. Harvesting takes place by hand and each parcel is worked by the same team of workers to increase the teams' familiarity with the individual vines. The harvest of the white
