This traditional winery with a history stretching back many centuries is located in the municipality of Wallhausen in the German wine-growing region of Nahe. It is the oldest family-owned vineyard in Germany in uninterrupted family ownership. The oldest known document on the vineyard ownership of the Dalberg family (which at that time still called itself Weierbach) comes from a property register of the year 1200 with the designation "Wingert in Summelachen" (today Sommerloch), or vineyard on "Breitwiesen" in 1217. The great-grandmother of Felix Prinz zu Salm-Salm, the present owner, was the last Dalberg. She married Prince Franz zu Salm-Salm in 1911. Michael Prinz zu Salm-Salm, the father of Prince Felix zu Salm-Salm, was president of the VDP (Association of German Prädikat Wine Estates) from 1990 to 2007, of which the winery is a long-standing member. The owners are Felix and Michael Prinz zu Salm-Salm, with Felix Prinz zu Salm-Salm as the farm manager.
