Kerpen produces Riesling from the Mosel, Germany's steepest and most celebrated wine region. The winery's portfolio centers on the Wehlener Sonnenuhr and Graacher Domprobst vineyards, sites that yield wines of remarkable concentration and complexity. The Wehlener Sonnenuhr Riesling Trockenbeerenauslese—a botrytized dessert wine of extreme ripeness—has been assessed by Wine Advocate, Wine Spectator, Wine Enthusiast, and Falstaff. The Graacher Domprobst Riesling Beerenauslese and Wehlener Sonnenuhr Riesling Beerenauslese follow in similar prestige. These are wines of crystalline acidity balanced against honeyed fruit and mineral depth, characteristic of the Mosel's slate-based terroir and cool-climate Riesling expression. The focus on late-harvest and botrytized styles reflects both the region's microclimate and the winery's commitment to capturing the full spectrum of ripeness that these vineyard sites can achieve.
