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.

SARL Le Pavillon is Maurice Gonzague's venture in the heart of the Libournais. In this sub-region of the right bank of Bordeaux, the idea is to make terroir wines. Therefore, the work in the vineyard is done respecting the vines, the terroir, and following organic guidelines. The same principles apply to the work in the cellar with traditional vinification. Here, the specificity is the composition of the vineyard, covered with 70% merlot and 30% Cabernet Franc, giving the wine elegance, fruitiness and freshness and a truly different character.
