The wine-growing region is located in the federal state of Baden-Württemberg in Germany. The vineyards cover 11,461 hectares of vines, stretching between Lake Con stance and the valley of the Tauber below Rothenburg (Taubergrund). The geographical and climatic conditions are shaped by many river valleys. On its very winding course, the tributaries Rems, Enz, Kocher and Jagst flow to the Neckar. On the riverbanks are many south-facing slopes with widely spaced vineyards. In summer there is enough sun to give red wines strength and colour. Two thirds of the vineyards are steep slopes or hillside sites. Heilbronn is the wine capital of Württemberg and, to a certain extent, of Germany, because the DLG (German Agricultural Society) competition is held here every year. Weinsberg is home to a teaching and research institute for vine breeding, where August Herold (1902-1973) created several successful new varieties such as Dornfelder, Cabernet Cubin, Cabernet Dorio and Cabernet Dorsa.
The soils are characterised by Keuper formations and, on the middle Neckar, by shell limestone islands. The climate is continental, with hot summers, sunny autumns and frosty winters. The favourable microclimate along the Neckar and the shell limestone and Keuper soils are particularly suitable for red wines
The wine-growing region consists of six areas with 17 large vineyards and 207 individual vineyards. The Kocher-Jagst-Tauber area, named after three rivers, lies in the north and is the only one to specialise in white wines. It is divided into two major vineyards, Kocherberg and Tauberberg. The Tauber Valley contributes the section from Tauberzell to Creglingen, the rest belongs to other growing areas. The predominant soil type is shell limestone.

By far the largest and most important area of Württembergisch Unterland is divided into the nine large vineyards of Heuchelberg, Kirchenweinberg, Lindelberg, Salzberg, Schalkstein, Schozachtal, Stauffenberg, Stromberg and Wunnenstein. The vineyards are mainly located in the middle and lower Neckar valley, as well as strongly fragmented into many small areas east of the Neckar along the tributaries Bottwar, Murr and Schozach. The climatic conditions and soils are somewhat different in this area. The terraced vineyards along the river banks are characterised by shell limestone, those away from it by Keuper. Well-known wine-growing communities with their single vineyards are:
The Remstal-Stuttgart area lies in the south-east of the wine-growing region. The vineyards are mainly located up to 400 metres above sea level in the Rems river valley. It is divided into five major vineyards: Hohenneuffen, Kopf, Sonnenbühl, Wartbühl and Weinsteige. There is a certain Riesling tradition in the area, which is somewhat cooler and has more precipitation. Well-known wine-growing communities with their single vineyards are:
