Weingut Knoll produces Grüner Veltliner from the Wachau, Austria's most prestigious white wine region. The winery's flagship wines—Loibner Grüner Veltliner Smaragd Reserve, Ried Kellerberg Dürnsteiner Grüner Veltliner, and Loibner Grüner Veltliner Smaragd Vinothekfüllung—demonstrate the mineral precision and stone-fruit intensity that define the region's terroir. Grüner Veltliner from Wachau combines high acidity with complex aromatics and a distinctive white pepper note, qualities that emerge from the region's steep, south-facing vineyards and continental climate. The Smaragd designation indicates wines of maximum ripeness and alcohol within Austria's strict classification system. Falstaff, Wine Spectator, Wine Advocate, and Wine Enthusiast have all assessed the winery's portfolio, recognizing the technical caliber of its Veltliners.
