Gustave Lorentz produces wines from Alsace's Grand Cru vineyards, focusing on the region's signature white varieties. The winery's portfolio centers on Riesling, Pinot Gris, and Gewürztraminer—grapes that thrive in Alsace's continental climate and mineral-rich soils. The Riesling and Pinot Gris from the Kanzlerberg Grand Cru site represent the winery's commitment to single-vineyard expression, capturing the terroir's distinctive character. The Selection de Grains Nobles Gewürztraminer, made from late-harvest fruit, exemplifies the region's tradition of noble rot wines—concentrated, aromatic expressions of Gewürztraminer's floral and spice-forward nature. These wines have been assessed by Wine Spectator, Wine Enthusiast, Decanter, Wine Advocate, and Falstaff.
