The winery is located in the municipality of Bacharach in the German Mittelrhein wine growing region. The company, founded in 1982, is managed by Dr. Randolf, who is also a professor for organic viticulture at the Geisenheim University of Applied Sciences. The trained restaurant specialist Martina Kauer manages the administration and sales. The two are supported by their daughters Lena and Anne. The vineyards cover almost four hectares of vines on exclusively steep slopes. These are the individual sites Beulsberg (Urbar), Kloster Fürstental and Wolfshöhle (Bacharach), Fürstenberg (Oberdiebach), as well as Oelsberg (Oberwesel). 95% of them are planted with the leading variety Riesling, the rest withPinot Noir.
Organic viticulture is practiced according to the rules of the organic association ECOVIN. The quality standard is a yield limitation of 50 to 60 hl/ha. The emphasis is on dry, mature Rieslings with tangy acidity, typical of their origin and variety. They are slowly fermented in stainless steel tanks in a temperature-controlled refrigerated environment and are stored on the for a long time. The basis is the "Kauer Riesling" and the "Spätburgunder Weißherbst TORNADO". The second one was born in 2005 due to a stormy storm out of necessity and has been produced annually ever since due to its success. In addition, bottle-fermented Riesling and Spätburgunder Weißherbst sparkling wines and oak-matured marc brandies are also produced.
