The soils on the Right Bank of Bordeaux are dominated by clay and limestone. The terroir and soil varies from château to château, the best vineyards have soils with limestone, clay, gravel, sand and iron deposits with some elevations, slopes and good drainage. Clay soils consists of very small particles from degraded limestone which have the ability to retain water and to allow the vines easily penetrate the soil, searching for nutrients. Merlot is the most important grape in the region, due to the clay rich terroir. Petrus is worldwide famous for its blue clay soils.

Château Le Puy belongs to the Amoreau family for more than 400 years. This 50 hectares family-owned estate is no recent convert to Biodynamic viticulture. Neither fertilizers, nor herbicides has been spread in Château Le Puy. The health of the soils has always been of the utmost importance in the domain. Even when the use of chemicals was the norm, the Amoreau family followed the ideas of André Birre, a mid-20th-century agronomist, recommending methods not unlike biodynamics. Because ecosystem is even more important than farming practices, Château Le Puy has another 50 hectares devoted to forests, fig trees, hazelnut trees, and beehives.
