Château d'Yquem is a 113-hectare wine estate in AOC Sauternes and the only one classified as a premier cru supérieur in the appellation. The vineyard is composed of Sémillon for 75% of the vineyard and Sauvignon for 25%.

The terroir of Yquem is exceptional thanks to the combination of coarse, warm and draining soils and a clay subsoil that perfectly conserves the water of the many nearby springs, with a perfect water balance allowing the formation of Botrytis and a high concentration.

The yields are very low: it takes a vine to produce a glass of Yquem! In a bad vintage, the estate may decide to abandon the entire harvest. Thus, Château d'Yquem was not produced in 1910, 1915, 1930, 1951, 1952, 1964, 1972, 1974, 1992 and 2012.

Since 1959, Château d'Yquem has been producing a second wine, Y d'Yquem.

Born in the Middle Ages when Aquitaine was English, Château d'Yquem became French in 1453 when Charles VII attached the region to the crown of France. The work of the vineyard and the practice of late harvesting are attested as early as the 16th century. The Sauvage family succeeded each other at the head of the Château, then from 1785, the Lur-Saluces family with Françoise Joséphine, a young widow and woman of strong character who was to be at the origin of the transformation of the estate with the construction of the cellar in 1826, the harvest by successive sorting and the development of the international reputation of Yquem wines. In 1855, Château d'Yquem became the only Premier Cru Supérieur classified at the request of Emperor Napoleon III for the Universal Exhibition in Paris and enjoyed tremendous success during the second half of the 19th century. In 1868, it was one of the first Western brands to be introduced in Japan under the leadership of Emperor Meiji.

In the 20th century, the phylloxera crisis and the First World War did not spare Château d'Yquem, which became a military hospital. The Marquis Bertrand de Lur-Saluces, an officer in the trenches, took over the estate after the war and ardently defended and developed the AOC Sauternes and the wines of Château d'Yquem. He was succeeded by his nephew Alexandre de Lur-Saluces in 1958.
The second half of the 20th century was difficult and he overcame a succession of bad vintages and the crisis of the wine trade with courage and rigour. Château d'Yquem was reborn with the beautiful 1975 vintage and the estate slowly recovered with constant investment. In 1999, it became the property of Bernard Arnault and the LVMH Moët Hennessy-Louis Vuitton group.
