Robert Klingenfus produces wines from Alsace's distinctive terroir, where cool continental conditions and mineral-rich soils shape aromatic white varietals. The winery's portfolio centers on the region's classic grapes: Riesling, Pinot Gris, and Gewürztraminer. The Pinot Gris Alsace Grand Cru 'Bruderthal' and Riesling Alsace Grand Cru 'Bruderthal' both draw from the same Grand Cru vineyard, expressing the site's character through different varietal lenses—the Pinot Gris offering richness and body, the Riesling displaying the mineral precision and acidity Alsace Rieslings are prized for. The Chaussure Gewürztraminer rounds out the range with the spice and floral intensity characteristic of the variety. Wine Enthusiast and Wine Spectator have rated these wines, reflecting their standing within Alsatian production.
