Ingrid Groiss works in Austria's Weinviertel, a region in Niederösterreich known for crisp, mineral-driven white wines. The winery focuses on Grüner Veltliner, the country's signature variety—a grape that thrives in the cool continental climate and produces wines marked by green apple, white pepper, and herbaceous character. The portfolio centers on three reserve expressions: Pankraz Grüner Veltliner Reserve, Sauberg Tradition Grüner Veltliner, and Reserve Grüner Veltliner In der Schablau. These wines have been assessed by Wine Enthusiast, Wine Advocate, and Falstaff. The Pankraz Reserve leads the range in critical reception. Each bottling reflects the terroir of specific vineyard sites within the Weinviertel, where limestone and loess soils shape the mineral spine and aromatic profile typical of the region's finest expressions.
