In addition to its Haute Valeur Environnementale-certified vineyards, since 2010 Maison Lanson has owned one of the largest organically-grown vineyards in Champagne: Domaine de la Malmaison, located in the heart of the Marne Valley. Based on observation of the vines and the climate, it is cultivated using organic methods that respect the fauna, flora, soils and people. The estate is a life-size laboratory for biodiversity and vine health. It demands meticulous care by the hand of man, who links practices handed down for generations with the most precise techniques, the fruit of a constant quest for innovation. The Domaine de la Malmaison team is on a human scale, driven by a love of nature and a job well done. They work in symbiosis with a demanding environment that demands precision, care and patience.
