Hirsch produces Grüner Veltliner from the Kamptal, a limestone-rich valley in Niederösterreich known for white wines of mineral precision and aromatic intensity. The winery's portfolio centers on single-vineyard expressions: Ried Gaisberg and Ried Lamm, both bottled Grüner Veltliner, demonstrate the variety's signature white pepper and citrus character alongside the region's chalky minerality. Ried Grub, also Grüner Veltliner, rounds the lineup. These wines have been assessed by Wine Spectator, Wine Enthusiast, Wine Advocate, and Decanter. Grüner Veltliner, Austria's flagship white grape, thrives in cool continental conditions, yielding wines marked by herbaceous notes, stone fruit, and crisp acidity—qualities that define the Kamptal's expression of the variety.
