Location and landscape
Ammerbuch is a municipality in the north-west of the district of Tübingen. Its territory extends at the edge of the Schönbuch and across the Ammertal; the elevations range from 342 to 565 metres. The Schönbuch’s Keuper forest step, around 100 metres high, falls from the orchard and grassland slopes down into the Gäu. On the southern boundary lies the Pfaffenberg as a preserved island of the Middle Keuper.
Geological setting
The landscape is shaped by Keuper formations, gypsum Keuper, Stubensandstone, Rhaetsandstone, reed sandstone, Muschelkalk and loess-bearing materials. A documented vineyard in Breitenholz lies on a mixture of gypsum Keuper, sandstone formations and marl.
Viticulture in Ammerbuch
Breitenholz is characterised by viticulture and agricultural part-time businesses. The officially delimited single vineyards are called Hinterhalde in Breitenholz and Pfaffenberg in Entringen. In the Hinterhalde, around 5.5 hectares of vines are cultivated, and at the Pfaffenberg around 2.5 hectares. The vineyards of the district of Tübingen lie in a historical and climatic border zone of viticulture and belong to the protected German winegrowing region Württemberg.
Farming and development
The mostly small vineyard plots have preserved their original structure and were not subject to land consolidation. Dry-stone walls and species-rich meadows characterise many areas; the steep slopes are often worked by hand. In the Ammertal, local producers work mainly on a part-time basis and press and market their wines themselves. Ammerbuch was formed on 1 December 1971 through the merger of six previously independent places, including the winegrowing locations Breitenholz and Entringen.
