Domaine de la Roche Bleue works the Upper Loire, where continental climate and chalky soils shape wines of mineral precision. The estate focuses on Chenin Blanc, the region's signature white variety—a grape that thrives in cool conditions and yields wines of remarkable aging potential and complexity. Jasnières Le Clos des Molières and L'Orée de la Berterie, both Chenin Blanc bottlings, demonstrate the winery's command of the variety's range: from taut, stone-fruit-driven expressions to deeper, more textured interpretations. A red blend of Gamay and Pineau d'Aunis, La Guinguette, rounds the portfolio with the lighter, earthier character typical of Upper Loire reds. Wine Enthusiast and Decanter have rated these wines.
