The acclaimed wine of Margaux benefits from the diverse soil types in the appellation. In general, Margaux has a very thin layer of topsoil, and the very best vineyards, above the Gironde River, have gravelly soils that encourage deep root growth and allow for good drainage. Because of the variations in soil, Margaux wines can range from delicately flavored to highly concentrated, from medium- to full-bodied. Yet all Margaux wines share a fragrant bouquet, silky texture and remarkable balance.
