Château Couhins
Château Couhins is a Graves estate with an unusually technical lens: a Grand Cru Classé de Graves for white wine, owned by INRAE and run as both producer and viticultural research site. The visit is strongest for travelers interested in Sauvignon Blanc, Pessac-Léognan soils, organic farming, and the practical science behind modern Bordeaux rather than château theatre alone.
