Around the winery a first plot of 63.3 acres is located south of Fieuzal and east of Chevalier.
This major section of the vineyard is surrounded by the "Landes" forest and benefits from one of the coolest micro climate of the Pessac-Léognan area. The limestone base of sandy argyles deposited at the end of the tertiary area emerges on the north of this plot. Most of the vines are rooted in brown soils resulting from the quaternary alluviums of the river Garonne. Very gravely on the edge of the crests, these compact brown soils restrict the available water and are the prime location of the vineyard's Cabernet Sauvignons. At the top of these crests vines are inserting their roots more deeply through a sandy overlay therefore limiting the summer stress for an ideal and well balanced expression of the Sauvignon Blanc and Merlot.
On the crests edges, the clayey subsoil generates early hydro stress favorable to the mineral expression of the Sauvignon, to the silky character of the Cabernet Franc and to the power of the Merlot.
Half a mile to the North West, between Fieuzal and Malartic-Lagravière, and around Château Bois-Martin (an estate property), another plot of 18.7 acres completes the vineyard together with 4.3 acres located near Carbonnieux. Those vines are planted on more recent alluviums resulting in more gravelly soils resting on hardpan subsoil. The southern orientation of the slops favorable to an early maturation and the low mineral fertility of the soil make them very complementary to the other vines of Le Sartre
