Michael Teschke works in Rheinhessen, Germany's largest wine region, where the Rhine's influence and continental climate create conditions for distinctive white wines. The winery focuses on Sylvaner, a variety that thrives in the region's slate and loess soils. The 19-29 Sylvaner and Blauer Sylvaner represent the core of the portfolio, with both wines rated by Wine Advocate. Sylvaner from this producer shows the grape's characteristic mineral precision and dry profile—qualities that define quality expressions of the variety in Rheinhessen. The Ersten unter Gleichen Sylvaner rounds out the range. These wines reflect the winery's commitment to a single varietal expression in a region where Sylvaner, Riesling, and Müller-Thurgau form the traditional backbone.
