huitres marennes oleron

The Fine de Claire Verte (green) Label Rouge


A product of superior quality, fine de claire Red Label, a label given by the French ministry of agriculture, is subjected to a highly demanding quality control regime. The oyster must be finished in claires at a density and for a duration rigorously defined by the regulations. It should be round and tightly shut, and correspond to an index of shape taking into consideration its length breadth and depth. The quantity of flesh is considered as a proportion of the total weight of the oyster. The Red Label fine de claire should present a characteristic green tint from its time in the claire. Finally, to guarantee optimal freshness the oyster should be sold and consumed a maximum of ten days after being taken from the water. The green colour, so highly appreciated, is the result of the presence of the naviculus micro algae, filtered by the oyster which retains the pigment marennine. This exceptional oyster is produced from October to May to respect its reproductive cycle and to guarantee them not to be milky.
