Charles Frey works the Frankstein Grand Cru vineyard in Alsace, a region where mineral-driven whites define the terroir. The winery focuses on Pinot Gris and Riesling—two varieties that thrive in Alsace's continental climate and limestone-rich soils. The Pinot Gris Alsace Grand Cru 'Frankstein' expresses the grape's characteristic richness and texture, while the Riesling from the same site captures the varietal's aromatic intensity and acidity. A Vendanges Tardives Pinot Gris, made from late-harvested fruit, adds depth to the portfolio. Wine Enthusiast, Wine Spectator, and Decanter have all rated Charles Frey's offerings, with the Frankstein Pinot Gris bottlings earning particular recognition among prestige critics.
