World-famous winery with headquarters in the castle of the same name on the famous Johannisberg in the Rheingau. It is said that Charlemagne (742-814) had a vineyard planted on the 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 vines. The basilica "John the Baptist" was consecrated in 1130 and gave the monastery and community their name. In 1716, the prince abbot of Fulda Konstantin von Buttlar (1679-1726) bought the remains from the elector bishop of Mainz Lothar Franz von Schönborn (1655-1729) for 75,392 florins, 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.
