Huîtres Marennes Oléron

The Groupement Qualité Huîtres Marennes Oléron (GQHMO) is a defence and management organisation (ODG): it works to preserve and showcase the terroir, local traditions, and oyster-farming savoir-faire of the basin. It manages four products—Fine de Claire PGI (IGP), Fine de Claire Verte Label Rouge, Spéciale de Claire PGI, and Pousse en Claire Label Rouge—drafting their specifications and overseeing compliance through inspection and control plans. A non-profit association under the 1901 law, it has existed in its current form since spring 2005 and brings together members with diverse activities: producers, affineurs and growers in claires, shippers, and merchants. The group is also active in foreign markets, undertaking trade missions to countries with strong purchasing power such as China, Singapore, Hong Kong, the United Arab Emirates, and Europe.

The company presents itself under the name of EARL Suire Père et Fils, a family-run oyster farm located at Le Fief du Fenard, in Saint-Just-Luzac, in the Marennes-Oléron basin. It offers Fines de Claire and Pousses en Claire Label Rouge, as well as Spéciales, which have won gold medals on several occasions at the Concours des Saveurs Nouvelle-Aquitaine—including one for its Spéciale Écaille d'Argent in November 2025.

According to a news item published on its website, the company ceased marketing its organic oysters as of 31 December 2025. In season, it also offers crevettes impériales and gambas.

EARL Les Claires d'Arceau presents itself as oyster farmers on the Île d'Oléron, based at the port of Arceau in Dolus-d'Oléron. The farm raises four varieties — Fines, Vertes, Spéciales, and Reines des Claires — sold online, on-site, and at seasonal markets: during summer on the Île d'Oléron, and during winter in Loire-Atlantique, Lot, Lot-et-Garonne, and Tarn-et-Garonne.

Located in the heart of the salt marshes of La Couarde-sur-Mer on the Île de Ré, La Rhétaise is an oyster shack run by two sisters: Jana takes care of farming, Charlotte of sales — a team effort passed down from generation to generation. Across a 7-hectare marshland production site, the farm raises open-sea and claire-finished oysters, as well as imperial prawns.

From Easter to All Saints' Day, La Rhétaise welcomes visitors for on-site tastings — featuring its own oysters and prawns, as well as mussels, whelks and clams — and offers a comprehensive tour of the farm to explain how oysters and prawns are raised in the marshes. Its spéciale de claire won the gold medal at the Concours Général Agricole 2026, in the Spéciales de claires category.

EARL Huîtres Vernet is a family-run oyster farm located in Bourcefranc-le-Chapus, in the heart of the Marennes-Oléron basin, in Charente-Maritime. The business presents itself as the fruit of four generations of oyster farmers: Loïc Vernet perpetuates the family's ancestral traditions and know-how, whilst modernising certain aspects of the operation. He describes himself as 'a peasant of the sea', advocating work carried out in communion with the natural environment.

The oysters are raised, selected and matured on site in order, according to the business, to offer the finest of the Marennes-Oléron terroir. The process of maturing in claires, which the farm presents as specific to this appellation, is said to give fines de claire oysters a less oceanic taste than those from the open sea. The operation, which the Vernet family describes as a passion pursued 365 days a year, falls within the Marennes-Oléron appellation area, which brings together more than 650 producers across 27 communes and approximately 3,000 hectares between the Charente and Gironde estuaries.

La Cabane du Grouin farms oysters and imperial prawns in Loix, on the île de Ré, in the marais du Grouin. Founded in 2002 by Frédéric Voisin, the farm established itself as the only organic oyster and prawn producer on the island. In 2022, after twenty years at the helm, Voisin handed the cabane over to Brice Kuhnlé, an engineer by training from Lorraine, who took over the farm after training as an oyster farmer.

A tasting area opened in 2019: visitors can sample oysters and prawns right where they are produced, on the terrace or under cover depending on the weather. Direct sales run all year round on site at Le Grouin, with extended hours from mid-June to mid-September; the farm also offers shipping, with oysters delivered within 48 hours. In 2026, its Fine de claire won the gold medal at the Concours Général Agricole.
