The Domaine des Ardoisières was created ex nihilo in 1998 on land that had been planted with vines in Roman times, but which had not produced wine for centuries. Michel Grisard, one of the leading Savoyard producers, was the driving force behind the project for a long time, before handing it over to the current manager, Brice Omont. The vineyard is cultivated according to biodynamic principles and vinification is extremely natural with as little intervention as possible. The property produces three white wines and two reds. The "Schiste" cuvée (7,000 bottles) is produced from four traditional Savoyard varieties: Jacquère, Malvoisie, Roussanne and Mondeuse Blanche. The vines are grown on spectacular south-facing terraces, with small yields of 25 hl/ha. Vinification, with indigenous yeasts is carried out in barrels which have already been used for three to five wines.

Améthyste is a blend of Persan and Mondeuse Noire. The latter variety brings structure and spice while the Persan offers finesse and a silky texture. On the nose, notes of blueberry marry with pepper and spices while the mouth is powerful yet balanced. A superb wine.
