Château Lespault-Martillac, since 2009 run by Olivier Bernard, also the proprietor of Domaine de Chevalier, has been making wine since Roman times; it is one of the oldest estates in Martillac, part of the Pessac Leognan wine appellation in Bordeaux. Its location overlooks the commune, rising up high on gravel and clay made soil.

Organic methods are used to prepare the soil and fight off any pests in the vineyard. Although small in size and only producing a low yield, the grapes from the vineyard are of very high quality due to the care and attention they receive.

The red grape varieties in the vineyard comprise 60% Merlot, 22% Cabernet Sauvignon, 13% Petit Verdot and 5% Malbec. The white grape varieties consist of 80% Sauvignon Blanc and 20% Sémillon.
