Adrian et Diego Mathier

Valais alpine wines: Marsanne, Cornalin, and Pinot Noir from Swiss terroir.

Adrian et Diego Mathier produces wines from Valais, Switzerland's largest wine region, where Alpine terrain and continental climate shape distinctive expressions of both indigenous and international varieties. The winery's portfolio centers on Marsanne, Cornalin, and Pinot Noir—grapes that thrive in Valais's demanding conditions. Gemma Ermitage, a Marsanne-based wine, demonstrates the region's capacity for mineral-driven white wines with structure and aging potential. Cornalin, a rare Valais native, offers dark fruit and spice characteristic of the variety's terroir-driven profile. L'Ambassadeur des Domaines Diego Mathier Red, crafted from Pinot Noir, reflects the cool-climate precision possible at this Alpine latitude. These wines have been assessed by Wine Spectator, Wine Advocate, Wine Enthusiast, Decanter, and Falstaff, positioning the winery within Switzerland's serious wine conversation.
