Location and settlement
Bollschweil lies in the Möhlin valley in the district of Breisgau-Hochschwarzwald in Baden-Württemberg. The historic settlement consisted of an upper and a lower village, which were separated from one another by the castle precinct.
The Steinberg
The Bollschweiler Steinberg has cultivation layers facing south-east. The subsoil consists of limestone from the main rogenstone formation, which was previously assigned to the Brown Jura epsilon. The partly massive limestone, which is locally oolitic, is strongly karstified and is threaded with reddish-brown hollows filled with clay. In the vineyard, the Jurassic limestone lies under a soil layer about 50 centimetres thick.
Viticulture and wines
At the Steinberg, viticulture has been documented for generations. Planted varieties include, among others, Gutedel, Riesling, Weißburgunder, Grauburgunder, Spätburgunder, Johanniter and Muscaris. The range of documented wines extends from dry and delicately off-dry white wines, via dry rosé, as well as dry and delicately off-dry Spätburgunders, to Riesling Sekt brut and Pinot rosé dry.
The described methods of work include gentle processing with as little intervention as possible, ageing selected premium grapes in oak barrels, organic fertilisation, cover cropping, reduced chemical plant protection, fungus-resistant vine varieties and hand harvesting.
History and wine-growing region
Bollschweil is documented in 1147 as Buolswilare and possibly already in 838 as Puabiliniswilare. The settlement was initially connected with St. Gallen and later with the St. Ulrich monastery. Wine from Bollschweil belongs to the protected designation of origin Baden.
