Domaine Marchand & Fils works the chalky, mineral-rich soils of Pouilly-Fumé in the Upper Loire, where Sauvignon Blanc reaches its most austere and complex expression. The winery's three flagship wines—Kimmeridgian, Kalcaire, and Les Kérots Pouilly-Fumé—each draw character from distinct terroirs within the appellation. Kimmeridgian, rated 92.5 by prestige critics including Wine Enthusiast and Decanter, captures the limestone-driven intensity the region is known for. Kalcaire (92.0) and Les Kérots (89.7) follow, each offering the high-toned minerality and structural precision that define Upper Loire Sauvignon Blanc. These are wines built on geology rather than oak or manipulation—expressions of place rendered through a single, exacting grape variety.
