The winery is located in the midst of hillside vineyards in the community of St.Magdalena near Bozen in the Italian wine-growing region of South Tyrol (Trentino-South Tyrol). The "Obermosergütl" was taken over by the Rottensteiner family in 1890 and is now in its fifth generation as an established small producer bottler. In addition to the sites around the winery, which was restructured in 2009, the Vigna Grafenleiten and the "Berg" vineyard in Obermagdalena are also managed in St. Magdalena. Above Lake Kaltern, the family also owns a vineyard in the Putz Mauer location. Since 2012 the winery has been managed by winegrower Thomas Rottensteiner.
The vineyards cover four hectares of vines, some of them on extreme steep slopes. They are predominantly planted with varieties of the two autochthonous grape varieties Vernatsch = Schiava (50%) and Lagrein (40%) in the classic pergola training system. As a white grape variety, Sauvignon Blanc is cultivated in the Guyot system. The careful and natural cultivation together with intensive manual work in the vineyards allows the renunciation of herbicides and the avoidance of treatments.
The red wines are aged in traditional small and large wooden barrels, the Riserva in tonneau and barrique barrels, the white wine in stainless steel tanks as DOC South Tyrolean. Together with other winegrowers of the zone, a lot of passion is invested in the site wine St. Magdalener Classico. The flagship is the Lagrein Riserva "Grafenleiten" (14 months barrel ageing). Every year, around 32,000 bottles of wine are marketed by the company itself. The winery is a founding member of the winegrowers' association Freie Weinbauern Südtirol.
