One-third of the wines produced in Austria are red; south of Vienna, warm breezes from the Pannonian Plain create optimal ripening conditions, & quantities are boosted by the high-cropping nature of Zweigelt, the country's most-planted red grape. The estate comprises more than sixty hectares of prime vineyard sites around Langenlois near Krems. Since the 1970's the Jurtschitsch brothers have used compost & green fertilization to nourish the soil, thereby preserving the ecological balance in the vineyards.
