The winery is located in the municipality of Wehlen, district of Bernkastel-Kues (Mittelmosel area) in the German Mosel wine-growing region. It is the ancestral estate of the Prüm family's holdings, which have since been divided up. It was founded by Sebastian Alois Prüm (1794-1871). After the death of his son Matthias (1835-1890), the estate was divided among his children in 1911. Sebastian Alois (1877-1959), named after the founder, got one of the largest parts. In 1971 the estate was taken over by his grandson Raimund Prüm alias "Roter Prüm". It was divided into six parts in 1964, but has since been largely reunited with the annexation of the Wehlener and Graacher vineyards of the Jos. Christoffel jr. estate. A guest house is attached. Daughter Saskia Andrea Prüm joined the winery in 2005 as a graduate viticultural engineer after several years of wandering in many wine-growing regions of the world and studying in Geisenheim, and took over responsibility for the estate in 2017. She is the first female winery owner in the family. Her initials also correspond to the name of the winery, as they did for the founder.
