Martin Muthenthaler works in Austria's Wachau region, where the Danube valley's steep terraced vineyards and continental climate shape distinctive white wines. The winery focuses on Grüner Veltliner and Riesling, the region's signature varieties. The Grüner Veltliner Viesslinger Stern and Ried Schön demonstrate the grape's mineral precision and structure in this terroir, while the Riesling Viesslinger Stern shows the variety's balance of acidity and stone-fruit character. These wines have been rated by Wine Advocate, Wine Spectator, and Wine Enthusiast. Wachau's cool-climate conditions and slate-rich soils produce whites of notable complexity and aging potential—wines that reflect the specific character of their vineyard sites rather than a single house style.
