An outstanding terroir
The Graves appellation: a mineral treasure from ancient times…
One of the natural gifts of Château Couhins-Lurton is undoubtedly its terroir: the famous gravelly soil of Bordeaux.
Its origin is intrinsically linked to the Garonne River. These “graves” consist of alluvial soil, sand, clay and pebbles of varying sizes. They were deposited in terraces near the Garonne paleo-river, due to the fact that its flow rate constantly fluctuated during the ice age, carrying stones from the Pyrenees or the Massif Central and swept along by the various river systems.
This geological formation, situated on an ancient asteriated limestone bedrock containing quartz, quartzites, and other agates, was formed in the late Tertiary and early Quaternary periods. Over thousands of years, deposits were gradually shaped by erosion, giving rise to a slightly hilly landscape, punctuated by a multitude of “gravelly rises”.
