World-famous winery with headquarters in the castle of the same name on the famous Johannisberg in the Rheingau. It is said that already Charlemagne (742-814) had a vineyard planted at Johannisberg for the first time. Between 1096 and 1100 Benedictine monks from Mainz built a monastery on the plateau of the Bischofsberg above the village of Johannisberg and also cultivated vineyards. The basilica "Johannes der Täufer" was consecrated in 1130 and gave the monastery and community its name. In 1716 the prince abbot of Fulda, Konstantin von Buttlar (1679-1726), bought the remains from the electoral bishop of Mainz, Lothar Franz von Schönborn (1655-1729), for 75,392 gulden, had the building demolished and erected a three-winged baroque palace building there as a summer residence. A huge, 250-metre-long cellar was added to the old cellar in 1721.
