Forstmeister Geltz-Zilliken produces Riesling from the Mosel region of Germany, focusing on the Saarburger Rausch vineyard. The winery's portfolio centers on late-harvest expressions of this noble variety. The Saarburger Rausch Riesling Trockenbeerenauslese, made from botrytized grapes, represents the pinnacle of this approach—a wine of intense concentration and complexity. The Auslese selections, designated by gold capsule variants, offer nuanced expressions of the same terroir at different ripeness levels. Riesling from the Mosel is characterized by its balance of natural acidity and subtle sweetness, with mineral precision that reflects the region's slate soils. These wines have been assessed by major international critics including Falstaff, Wine Enthusiast, Wine Advocate, Wine Spectator, and Decanter. The winery's specialization in botrytized and late-harvest Rieslings demonstrates a commitment to capturing the full potential of the vintage and vineyard.
