Ormes de Pez has been part of the Medoc landscape since the 18th century. At the time of the French Revolution, the current property was called the Domaine de Pez (meaning ''peace'' in the local dialect). As for the elms (''ormes'') that have appeared on the bottle labels since 2003, they grew on the grounds of the domaine until this mythical variety of tree ceased to grow in Europe in the 1950's.

From the 19th century onwards, the château had numerous owners (Southard and Pieck, Berthé, Carrère, Alibert, Meiners and Allemand, Eschenauer, Johnson, Miaihle), before becoming a part of the Cazes family. In around 1880, Marie Cazes married Jean Guillou, the Ormes de Pez Cellar Master. He was sadly killed at the very beginning of the Great War and so Marie, a woman of great character, subsequently took over the business. Her brother Jean-Charles Cazes purchased Ormes de Pez in 1940. Jean-Michel Cazes later redeveloped and modernised the traditional XVIII century buildings in the early 80's.

Château Ormes de Pez lies 60 km from Bordeaux on the Médoc peninsula. It benefits from a mild ocean climate thanks to its proximity to the estuary and the Atlantic ocean.  Its 40 hectares of vineyards consist of two very distinct terroirs: the Cabernets thrive on the gravelly parcels composed of quartz and rolled pebbles whereas Merlot is best-suited to the cooler, sandy-clay parcels. These parcels have good drainage properties and are representative of the Saint-Estèphe appellation. Vines are planted in accordance with the traditional Médoc planting ratio. Cabernet Sauvignon counts for 54% of plantings, complemented by 37% Merlot, 7% Cabernet Franc and 2% Petit Verdot.
