Domaine du Haut Bourg produces Muscadet from the Côtes de Grandlieu, a maritime appellation in France's Atlantique region. The winery works with Melon de Bourgogne, the traditional grape of the Loire's westernmost whites—a variety prized for its mineral precision and bracing acidity. The Origine du Haut Bourg and Signature du Haut Bourg bottlings represent the domaine's core range, each expressing the chalky, slate-driven terroir of their vineyard site. Wine Enthusiast, Wine Advocate, Wine Spectator, and Decanter have all assessed the winery's releases. Muscadet from this corner of the Atlantic coast tends toward lean, saline profiles with subtle stone-fruit notes—wines built for seafood and aperitif drinking rather than extraction or oak. The Côtes de Grandlieu designation signals a focus on the appellation's cooler microclimates and older vines, where Melon achieves both ripeness and tension.
