The production area is located in the federal state of Baden-Württemberg in Germany and is divided into southern Baden and northern Baden. It extends almost 400 kilometres from Lake Constance along the Upper Rhine Plain via the Badische Bergstrasse and Kraichgau to Tauberfranken. The vineyards cover an area of 15,828 hectares. To the north is the city of Heidelberg with the oldest German university, founded in 1386. The Baden Wine Route begins to the north of this city and leads to Ortenau in southern Baden. Already in the 2nd century, viticulture spread from Lake Constance to the north. It reached its peak in the 16th century.
