6 Generations of Enthusiasts
Chironfils oyster company values its distinctiveness on the Marennes Oleron basin.
Very few oyster farmers have this continued presence for so long.
Over the years, the company created by Mr CHIRON has successfully developed and diversified in order to always be adapted to the evolving market.
Experience & Tradition
La Seudre, Oleron island, Marennes and l’Eguille
Spats are gently removed from the perfect collecting areas of Aix island. Nature gives its best there. The Chiron family possesses oyster parks and ‘Claires’ which are located between Marennes, Oleron island and Ré island ; Packaging and shipping processes are carried out in the original site of l’Eguille.
The traditional maturing technique in ‘Claires’ enables the company to produce the four certified qualities ‘Huitres Marennes Oleron’. The annual production is 250 tonnes and 90% of these oysters are maturing in our ‘Claires’. Most of the supplies come from our parks, and the rest are locally supplied by our historical partners.
A lot of Innovation
Longline oyster – a jewel in the ocean
Our company is the pioneer of the longline culture of oysters in the open sea. It has established a longline oyster farm off the coasts of the islands of Ré and Oléron. This unique know-how which has been patiently developed since 2002 has moved from experimental stage to production stage, thus could produce up to 150 tonnes a year. This innovative system requires traditional labour. Bags are suspended in permanently immersed cages in the open sea. This system never disrupts the natural cycle of oysters, and the quality of the oysters grown using this method is higher than the quality of those using the traditional method. After maturing in the ‘Claires’, our oysters become real treasures – special oysters prized for their rich flesh and character. They are the ‘Speciale Chironfils’ oysters resulting from the perfect combination of tradition and modernity.
Quality & Certification
Protected Geographical Status and two Red Labels for the Oysters of Marennes Oleron Since 1989 when they won the first Red Label for a maritime product (Fines de Claires Vertes), the oyster producers of Marennes Oleron have decided to fight for the quality of their product.
In 1999, a second Red Label is won for La Pousse en Claire, the top of Marennes Oleron oysters.In February 2009, the European Union registered Marennes Oleron oysters with the Protected Geographical Status Label, bringing to fruition twenty years of hard work in favour of high quality.
Finishing in « Claires », a true speciality of the Marennes Oleron basin, is now recognised at a European level and extends over 3,000 hectares between the Seudre river and the Island of Oleron.
Refining in Claires is a real particularity of the Marennes Oleron basin recognized at the European level. The territory stretches on more than 3000 hectares between the Seudre river and the Oleron island.
The oysters have a special refined taste due to this unique technique.
