Schloss Johannisberg, the First Riesling Wine Estate of the World! Schloss Johannisberg is a castle and winery in the village of Johannisberg to the west of Wiesbaden, Hesse, in the Rheingau wine-growing region of Germany. It has been making wine for over 900 years. It was here, at the first Riesling wine estate of the world that the first Spätlese (late harvest) and Eiswein (ice wine) was first produced.
Since 1720, only Riesling is cultivated on its single vineyard, and hand picked during each harvest. Consider as the royalty of Rieslings, Schloss Johannisberg is a must try for every Riesling lover.
