Alzinger produces Riesling and Grüner Veltliner from steep terraced vineyards in Wachau, Austria's most prestigious white wine region. The Dürnsteiner Liebenberg Riesling Smaragd and Smaragd Höhereck Riesling represent the winery's focus on the region's signature dry style—mineral-driven, high-acid wines shaped by the Danube's microclimate and ancient schist soils. The Loibner Loibenberg Grüner Veltliner Smaragd showcases Austria's other flagship variety, known for its white pepper spice and herbaceous complexity. Smaragd, the top classification in Wachau, denotes wines of maximum ripeness and alcohol (12.5% minimum). Falstaff, Wine Spectator, Wine Advocate, Wine Enthusiast, and Decanter have all assessed the winery's portfolio, reflecting its standing among serious collectors of Austrian white wine.
