Reichsrat von Buhl in the Rheinpfalz has been family-owned for over 150 years and today is the property of Baron von und zu Guttenberg. In 1989 he leased the property to the Japanese Sanyo group which has invested millions of yen in both the cellars and the vineyards during the last 10 years.

There are 55 hectares of vineyards, including prime holdings in the villages of Forst, Deidesheim and Ruppertsberg. Winemaker Frank John produces forthright wines, made in an overtly fruit-driven style which makes them delicious while young, although the top wines also have tremendous ageing potential.
