The ne plus ultra of oyster culture, France farms more oysters than anywhere else in the world. Most of these are Pacifics, though the native European Flat still shows up in Brittany. France also goes to greater lengths than anywhere else in the world to coddle some of its oysters, which can be finished in special salt ponds where each gets a designated amount of water, or may even have special algae added to turn their gills green (and flavor fruity).
