History of Ch. Lanessan is exceptional - from 1310 until today it has belonged to just two families. It was owned by the descendants of Henry de Lanessan until 1793, when it was bought by Bordeaux wine merchant Jean Delbos. At that time, the vineyards covered 24 hectares.
Lanessan has always had an excellent reputation and in 1814 was ranked as a 4th cru in terms of quality. Unfortunately for the château, in 1855 the then owner Louis Delbos refused to give samples to the Paris Exhibition, thus excluding Lanessan from the future Grand Cru Classé classification in which it would otherwise have been included.
In 1878, a neoclassical renovation of the château and the cellar used for vinification began. In the 1960s, a descendant of the original owners, Jean Bouteiller, expanded the vineyards to an area of 80 hectares.
Vines for wine with the Ch. Lanessan vines mature on 45 hectares of this area. The vineyards are located on a single parcel of land in the appellation of Haut Médocadjacent to the St Julien appellation.
Since 1999, a second wine , Les Calèches de Lanessan, has been produced. In 2004, the grape sorting was improved with its own two-stage system. In 2010, further progress was made in the vineyard with soil analyses, and progressive methods were introduced in the cellar for vinification and wine training.
