Denis and Didier Berthollier cultivate 12 hectares of vineyards using organic and biodynamic farming practices. Located on the slopes of the Savoyard mountains, just 10 kilometers from Chambéry, at the crossroads of the three valleys of Chambéry, Grenoble, and Albertville, their estate is a true gem for wine enthusiasts.

 The harvest and sorting are carried out entirely by hand. Vinification is done without sulfur, utilizing indigenous yeasts, with a light sulfiting at bottling. The wines are aged in barrels, demi-muids, and amphorae.

 They produce around ten cuvées, either single-parcel or blended:
 - Chignin "Vieilles Vignes," white, made from the Jacquère grape
 - Chignin "Argile sur Schistes," white, single-parcel, made from the Jacquère grape
 - Roussette de Savoie "Baron Decouz," white, single-parcel, made from the Altesse grape
 - Chignin Bergeron "Exception," white, made from the Roussanne (Bergeron) grape
 - Chignin Bergeron "Les Salins," white, single-parcel, made from the Roussanne (Bergeron) grape
 - Rouge de Savoie "Sel de Marius," red, made from the Pinot Gamay grape
 - Rouge de Savoie "Et ma goutte de ...," red, made from the Mondeuse grape
 - Rouge de Savoie "Les Granges Tissot," red, made from the Mondeuse grape
 - Rouge de Savoie "Arbyola," red, made from the Persan grape

Terroir:
 One-third of the vineyard features vines on stakes in terraced and steep slopes, situated on clay-limestone scree. Another third consists of trained vines on mid-slopes, also on clay-limestone scree. The final third is located on glacial moraine.

 This unique terroir, combined with meticulous farming and winemaking practices, results in wines that truly express the character of the region.
