Jean Delbos, a Bordeaux wine merchant bought the property, made up at the time of 24 hectares (60 acres) of vines.
Architect Henri Duphot finished construction work on the present Chateau. Its neo-classical style is inspired by Tudor influences. The winemaking cellar was also built.
Marie-Louise Delbos, Jean Delbos’s grand-daughter, married Étienne Bouteiller.
Their son, Jean Bouteiller, gradually increased the size of the vineyard up to 80 hectares (nearly 200 acres), including the 45-hectare (110-acre) Lanessan vineyard. One notable addition was the vineyard of Château de Sainte Gemme and Lachesnaye.
The estate’s second wine “Les Calèches de Lanessan” was launched.
A major investment and technical development programme that allows Lanessan to keep up to date with the latest technology.
Associated with the technical changes of the 2000s, the arrival of Eric Boissennot, an emblematic oenologist from the Médoc, who has been succeeding his father (Jacques) for more than 10 years, will bring a touch of modernity to the Grand Vin de Lanessan.
The Bouteiller family decided to no longer manage the estate, and entrusted it to Ms. Paz Espejo, an oenologist from Madrid, who will hold her position until 2020.
Lanessan is committed to a virtuous environmental process that will enable it to obtain the HVE3 label (High Environmental Value level 3), as well as the ISO 14001 level.
Lanessan continues its technical evolution in line with the HVE3 label (soil work, preservation of fauna and flora) and is equipped with the optical-sorting process, in order to strive for ever greater precision in the selection of the berries that will be used to make the Grand Vin de Lanessan.
Lanessan is now equipped like the Grands Crus.
