The 40 to 50-year-old vines are grown on original European rootstocks. 70% of the grapes come from the staircase-steep amphitheatre-shaped vineyards of Urziger Wurzgarten. The volcanic rhyolitic soils are layered with red slate. Due to the southern exposure and the protective rocks, Ürziger Wurzgarten is one of the warmer microclimates, producing opulent, aromatic, spicy Riesling with a typical zesty finish. 30% of the fruit comes from Erdener Treppchen, located one kilometre downstream, where the terroir, microclimate, and resulting wines are entirely different. Due to its western orientation, the slightly lesser gradient, and the lack of slate cliffs, Erdener Treppchen is cooler, which, combined with the blue slate soil, produces more delicate wines with racy acidity. The vines are VSP trained, allowing easy canopy management on the steep gradient. Summer leaf removal provides good air circulation and reduces photosynthesis, resulting in a later harvest, producing berries with less sugar, less alcohol, and good aromatic maturity. Hand harvested.
