Marie-Thérèse Chappaz, a vintner hailing from Valais, Switzerland, is revered as a true luminary in the region, crafting remarkable wines that particularly shine in her exquisite sweet dessert wines and the Petite Arvine varietal, indigenous to the Valais and cultivated since 1602.

Nestled amidst the precipitous vineyards of Fully in Valais, Switzerland, her domaine spans across 8 hectares, meticulously tended to with organic and biodynamic practices. A founding member of Les Artisanes de la Vigne et du Vin, she champions artisanal winemaking with utmost dedication.

Notably, in 2023, The Robert Parker Wine Advocate awarded Marie-Thérèse an extraordinary score of 100—a perfect rating—for her Grain par Grain Petite Arvine Domaine des Claives, affirming her mastery of the craft.
