St. Christopher produces Riesling from the Mosel region of Germany, drawing on vineyard sites in Piesport known for their slate-rich soils and steep terrain. The winery's portfolio spans the classic German Riesling hierarchy: Kabinett, Spätlese, and Auslese expressions from parcels including Goldtröpfchen and Michelsberg. These designations reflect increasing ripeness and sweetness, from the delicate, mineral-driven Kabinett through the richer, more concentrated Auslese. Mosel Rieslings are characterized by bright acidity, aromatic intensity, and the ability to balance residual sugar with freshness. Wine Enthusiast and Wine Spectator have rated St. Christopher's releases, with the Piesporter Goldtröpfchen Riesling Auslese and Spätlese among the winery's highest-rated offerings.
