The Maison du Vigneron is a haven of traditional skills and unbeatable winemaking knowledge, producing a full selection of wines and Crémants from the Jura and Savoy regions. The Maison du Vigneron is the main protagonist in the Jura wine country, and contributes to the reputation of the entire region. It is regarded in the Jura as one of the region's principal producers of Crémants. For generations now, the Maison du Vigneron has devoted itself to vinifying, maturing and distributing exceptional Jura wines and Crémants, also from Savoy.

In addition to the AOP wines, the Maison du Vigneron also specialises in producing Vin Jaune and Vin de Paille, true gems of the Jura region. (Vin Jaune and Vin de Paille are both AOP-certified).

The vineyards that produce the grapes for Le Clos Petraz have an unusual location: they are situated in the regional natural park of the Bauges massif, now boasting the UNESCO Global Geopark label.
