Baden is a wine-growing region in Germany, with a vineyard area of 15.866 hectares it is the third-largest in Germany, and the most southerly. It stretches over a distance of more than 300 kilometres from Lake Constance along the plains of the upper Rhine via the Badische Bergstraße route and the Kraichgau region to Tauberfranken. Around 85% of the total vineyard area is worked by the members of around 100 wine co-operatives. They utilise the facilities of the huge central winery complex of the „Zentralkellerei Badischer Winzer", founded in 1952, which is one of the largest wine co-operatives in Europe. The large growing area is broken down into North Baden and South Baden Because of its unusually warm climate (for Germany), Baden is the only wine-growing region in Germany that is classified as being in EU climatic zone B, that puts it in the same zone as Alsace, Savoye and the Loire in France, Austria, too, is in the same zone (also see under wine laws).The south-facing slopes of the Kaiserstuhl mountain, an extinct volcano, in the vicinity of the two communes of Achkarren and Ihringen, are the warmest region in Germany. For this reason, excellent red wines are grown in South Baden. The city of Heidelberg lies in the North, with the oldest university in Germany, founded in 1386. The palace in Heidelberg houses the oldest wine barrel in the world. The well-known Badische Weinstraße wine route begins just north of the city, and leads visitors through the vineyards as far as Ortenau in South Baden. The Baden wine-growing region has been subdivided into nine sub-zones: Badische Bergstraße, Bodensee, Breisgau, Kraichgau, Kaiserstuhl, Markgräflerland, Ortenau, Tauberfranken and Tuniberg, with 15 large regional sites and 315 individual single vineyard sites.
