The oldest traditional activity in Marennes-Oléron is wine production. It appeared as early as the end of the 3rd century. But it was during the 6th and 7th centuries that wine production really developed after the massive deforestations.
Salt and wine trade were then the major production activities in Oléron Island. At the end of the 19th century, phylloxeras decimated most of the grape crops. This misfortune lead to a change of hands. The laborers bought the vineyards off the original owners. As a result the properties were split and 5 wine cooperatives were created in Oléron. Nowadays, Oléron's vineyards are spread over 1730 acres mainly in the north of the island. Twelve properties are producing pineau, wine, cognac and liqueurs. There is one wine cooperative left which is situated in Saint-Georges d'Oléron.
