Located in the Pessac-Léognan appellation, Château Haut-Brion is the only wine in history to be dual-classified as both a First Growth from the 1855 classification and a Classified Growth of the Graves. The vineyard’s secret lies in its remarkable "gravels"—small quartz pebbles deposited over millennia—which sit atop a complex subsoil of clay, sand, and limestone. These mounds provide natural drainage and an ideal orientation for the vines. In harmony with this exceptional terroir, the estate practices gentle, sustainable viticulture. By eliminating insecticides and preserving four hectares of wooded parkland, the property serves as a vital biodiversity reservoir, providing a sanctuary for dozens of protected bird species and rare insects like the Great Capricorn beetle.
