Marie Bernard Gillioz

Alpine Valais whites and rare reds from Switzerland's indigenous varieties.

Marie Bernard Gillioz works with the distinctive indigenous varieties of Valais, Switzerland's premier wine region. The winery's portfolio centers on two white wines of particular note: Sion Petite Arvine and Sion Heida, both expressions of grapes that thrive in Valais's Alpine terroir. Petite Arvine brings mineral precision and aromatic complexity to the region's white wine tradition, while Heida—the local name for Savagnin—offers textural depth and aging potential. The winery also produces Sion Humagne, a red wine from Humagne Rouge, a rare Valais variety. Wine Advocate has assessed the portfolio, recognizing the caliber of these site-specific bottlings. The wines reflect Valais's continental climate, steep vineyard slopes, and the particular character of grapes that have been cultivated here for generations.
