Weingut Hermann Dönnhoff is a German winegrower and producer based in Oberhausen an der Nahe. A municipality in the district of Bad Kreuznach, in the wine-growing region of the Nahe, in Rhineland Palatinate in Germany. The Hermannshöhle is the main location of the winery. A small mine tunnel in the middle of this location ("cave") is responsible for the name. Hermann is derived from Hermes, the Roman god of the protection of messengers and travelers. Probably a reference to an ancient place of worship at this point. The Dönnhoff family has been making wine in this region since 1750. Grandfather Hermann Dönnhoff already had a great passion for Riesling and gave a lot of attention to wine making and the purchase of the best vineyards in the area. His son Hermann junior continued this tradition. Helmut Dönnhoff took over the estate from his father Hermann junior in 1971. He was then 22 years old. The company had already become a pure winery. The last generation is Cornelius Dönnhoff, who has been responsible for the cellar since 2007. The company now covers 25 hectares. The vines grow on steep slopes in a volcanic landscape. The soils are mostly black-gray slate, interspersed with igneous volcanic rock.
Helmutt was described by Robert Parker as a superstar of the region. He was named German Winemaker of the Year in 1999 by the Gault Millau Guide to German Wines.
