In the 1930s, Marcel Ott bought Clos Mireille, an ancient wine property located in La Londe-les-Maures by the Mediterranean Sea and near the Fort de Brégançon. He then replanted and reassembled the vineyard around the old building built by the Benedictine monks in the 18th century. The estate owes its specificity to its schistous ground, the clayey earth devoid of limestone that outcrops on the old rock, the local microclimate, the sea spray, and its wide maritime frontage. The wines produced at Clos Mireille have benefited from the Côtes-de-Provence PDO appellation since 1936.
