The winery is located in the municipality of Vogtsburg-Oberrotweil (Kaiserstuhl area) in the German Baden
wine region. The origins of the family go back to the 15th century. The great-grandfather of today's owners, Josef Bercher, bottled wine as early as 1900. In the 1950s, the Wiedemann and Bercher families jointly ran the Josef Bercher Erben winery. It was taken over in 1985 by Beate Wiedemann-Schmidt and Franz Wilhelm Schmidt. Since 2007, son Fabian Schmidt has been responsible for the development of the wines. The vineyards comprise ten hectares of vineyards with a total of 52 scattered plots in the individual locations Feuerberg
(Burkheim), Enselberg, Rosenkranz and Steinbuck
(Bischoffingen), as well as Henkenberg
(Oberrotweil). They are planted with the red wine varieties Pinot Noir and Nebbiolo, and with the white wine varieties Pinot Gris, Pinot Blanc, Riesling, Müller-Thurgau, Silvaner, Auxerrois, Kerner, Gewürztraminer and Muscatel
Quality criteria in the vineyard are healthy grapes without pest infestation through extensive foliage work, as well as yield reduction through strict pruning and thinning out
. The healthiest and optimally ripe grapes are harvested by selective harvesting in several passes. The wines are vinified separately according to location or soil/microclimate to bring out the different characters. The white wines are fermented without aroma yeasts and are classically matured in steel tanks (no barrique). The red wines mature in large wooden barrels or partly also in barriques. Since the 1999 vintage, wines from the top sites are marked with 3 stars. In years with suitable weather conditions, ice wines are also pressed. Beate Wiedemann completed her studies of painting at the university of Freiburg. She designs artistic labels and regularly organizes vernissages at the winery.
