The gorgeous Château de Chaintres is a 15-hectare estate established in 1675 by the Oratorian monks of the Notre Dame des Ardilliers, situated in the heart of Saumur-Champigny on soils of sand, clay, and tuffeau chalk. In 2018, the estate—having already practiced organic viticulture for over a decade, converted to full-on biodynamics (certified as of 2020), and dialed in their already-solid cellar work to attain new levels of freshness and precision. The estate’s phenomenal Saumur Rosé is pure Cabernet Franc, pressed directly, fermented spontaneously, and raised in steel with a bare minimum of sulfur. “Les Hirondelles” is a tangy, vivacious, brazenly energetic wine that speaks clearly of both variety and terroir.
