The Rebholz estate, in the southern Pfalz region of Germany, is a pioneer in organic and natural winemaking. The estate has been certified organic since 2005 and practicing biodynamic since 2006. However, even as far back as 1951, Eduard Rebholz (1889-1966), who received the title Ökonomierat, an honorary title conferred upon a deserving agriculturist, was commenting on his natural approach: "You will receive only natural wine from my cellar, wine that is the result of intense and loving cultivation of the vines and of similar vinicultural methods (no chaptalization, no artificial addition of a Süßreserve or similar fundamental structural changes that alter the native character of the wine and, in my eyes, mean that it is no longer a natural product."  

This tradition continues with the current generation; Birgit and Hansjörg Rebholz together with their children Hans, Valentin and Helene work as close to nature as possible. In an effort to promote a healthy ecosystem and to protect the environment, they forgo the use of herbicides, synthetic fungicides and mineral fertilizers. They use only organic and biodynamic techniques and materials that promote healthy plants, helping the vines grow strong and prosper naturally. While these methods involve more time and effort, it is a price they are willing to accept in order to best protect and preserve the biodiversity within their vineyards

The earliest recorded history of winegrowing by the Rebholz family in Siebeldingen dates back to 1632. From beer brewer to village mayor, family members have held a wide range of titles over the years. The single constant: always at least one winemaker in the family. Around 100 years ago the Rebholz clan took the estate house, first built in the 16th century, as their family home. The Rebholz family only began bottling their wine following the Second World War, as an alternative to delivering entire barrels to local inns and restaurants.
