The region’s name is derived from the Kamp river and its centre is Austria's largest wine town, Langenlois. With 4,000 hectares under vine, the Kamptal is one of Austria's larger winegrowing areas. Riesling and Grüner Veltliner are the main varieties. The Kamptal is home to the exceptional Heiligenstein vineyard, known for the "hell-like" insolation that influences the hot, dry mesoclimate. The soil dates back 270 million years to the Permian age, and is composed of desert sandstone with volcanic particles.
