The wine-growing region of Kremstal lies northwest of Vienna in the province of Lower Austria. It is bordered to the north and east by the Kamptal wine-growing region, to the south by the Traisental valley and to the west by the Wachau region. In the northwest, the Krems Valley borders on the Waldviertel. The Krems River, which rises in the Waldviertel and flows into the Danube east of the town of Krems, gives the area its name. The Danube flows through the Kremstal wine-growing region from west to east.
The area under vines in the Krems Valley covers around 2,300 hectares and can be divided into three zones: the Krems river valley including the city of Krems in the west of the area, the Lösster terraces east of the city and the wine villages south of the Danube around the Benedictine Abbey of Göttweig. More than half of the area is planted with Grüner Veltliner, followed at a distance by Zweigelt, Riesling and Rivaner. Grüner Veltliner and Riesling are also the two varieties approved for the Kremstal DAC and Kremstal DAC Reserve designations of origin.
