The geological maps of our vines and the historical maps of the Médoc dating from the end of the 17th century (Anonymous) and the 18th century (Belleyme 1785), provide evidence of the excellence of the soils of Lamarque . |
 |
The soils are characterised by the predominance of layers of gravel of the Riss I and Mindel III types (geological formations of the quaternary era) |
 |
The essential process in geological terms was the destruction of the terraces by erosion. It is this erosion process that explains the presence of gravel “ridges” on our three plots of vines: La Curade, Bahura, Maucaillou .
This uneven terrain plays an essential role in the drainage of rainwater. |
