Schloss Reinhartshausen produces wines from the Rheingau, Germany's premier Riesling region. The estate's portfolio centers on Riesling in its varied expressions—from the dry Erbach Schlossberg Erstes Gewachs to the luscious Hattenheimer Wisselbrunnen Auslese—alongside Spätburgunder, the region's signature red variety. The Rheingau's steep slate and loess soils, warmed by the Rhine's reflection, yield wines of mineral precision and aromatic intensity. Riesling here balances high acidity with stone fruit and floral complexity; Spätburgunder develops silky tannins and red cherry depth. Schloss Reinhartshausen's wines have been assessed by Falstaff, Wine Spectator, Wine Enthusiast, and Wine Advocate, with the Erbach Schlossberg Erstes Gewachs and Höllenberg Spätburgunder among its highest-rated releases. The winery's focus remains on the classical Rheingau style: elegant, terroir-driven, and built for the table.
