Bruno Lupin is a winemaker with extensive experience. Before moving back to his hometown to establish his own estate, he ran the cellar at La Cave de Genève in Switzerland for many years.
The Lupin estate consists of five hectares of vines in Frangy on a hillside called Les Aricoques. Bruno considers this location the best in the region due to the full southern exposure and the relatively low altitude that protects the vineyards from the cold northern winds. The soils are molasses, a crumbly calcareous soil resulting from old mountain erosion. Most of the vines are about 25 years old but there is a single parcel of individually staked vines that are over 60 years old. This site is the source of his old vines wine: "Cuvée du Pépé".
The wines are fermented with indigenous yeasts and are never de-acidified (although it is a common practice in the area). Bruno works his vineyards organically most of the time.
