The winery is located in the municipality of Beilstein (area Württembergisch Unterland) in the German wine-growing
. The name is derived from the former wine denomination
"Sankt Anna und Ruhl", which is located on the slope of the Fohlenberg directly above the location of the current winery. In 1830, a chronicle mentions this sunny hollow as "the best Beilstein site with particularly advanced timing of the grapes for an excellent wine"
. An icon of St. Anna (Mother of Mary) can be found on the new winery building. The family business is run by Renate and Hans Wiedenmann, son Marcel is responsible for the cellar. As a recognised training company, the winery has been involved in the training of young winemakers since 1989. The vineyards cover ten hectares of vines in the single vineyard Wartberg (Beilstein)
The classic local grape varieties are cultivated. These are the white wine varieties Riesling and Kerner, and for the red wine varieties Trollinger, Lemberger, Schwarzriesling, Samtrot and Spätburgunder. Since the 1950s, specialities of the house have been Pinot Gris and Gewürztraminer, as well as the new varieties Cabernet Cubin and Cabernet Dorio. From 2009 onwards, a purely ecological cultivation was gradually introduced. Marcel Wiedenmann produces wines under the label "Generation MW" according to his own philosophy. He also produces fine spirits (wine, marc, cherry, Williams, quince), grape juices, sparkling wines and bottle-fermented sparkling wines.
