The many extinct volcanoes east of Graz give a rich soil which imparts a spiciness to the variety of grapes grown in Southeast Styria. The climate is a little cooler here, especially at night, giving a long growing season resulting in wines that are crisp, aromatic and full bodied.
1,300 hectares of vineyards are cultivated - all located around Klöch, Sankt Anna am Aigen and Straden and situated primarily on the slopes of the extinct volcanoes which characterize the landscape. Some vineyards are up to 650m above sea level. Viticulture is generally a part-time job for wine-growers; their produce is sold mainly in the numerous Heurigen.
The main grape varieties grown in this region are Welschriesling, Chardonnay (called Morillon), Weißburgunder (Pinot Blanc) and Grauburgunder (Pinot Gris), Gelber Muskateller, the Traminer family, Sauvignon Blanc and Riesling; red wines feature Zweigelt as well as other grapes, including St. Laurent or Blauburgunder (Pinot Noir).
