Austria's 51,000 hectares of vineyards are concentrated in the east and southeast of the country, with the vast majority of its varied and individual wines orginating from the provinces of Lower Austria and Burgenland. The Kamptal district of Lower Austria produces some of the country's most concentrated Grüner Veltliners, the national speciality, as well as fine Rieslings, and is home to a number of Austria’s most innovative winemakers. In contrast, Burgenland’s sunnier climes are producing increasingly high quality red wines, particularly from Blaufränkisch and the indigenous Zweigelt.
