Kys Marine oysters are farmed in Brittany, in the sea near Quiberon, between Carnac and Riantec. The company manages the entire production process from oyster seed to sale, using its own cultivation system. The oyster beds cover approximately 10 hectares and are located in open sea, which contributes to even growth and strong shell formation. The oysters are farmed by Corinne Raguenel and Christophe Callewaert, with continuous attention to quality and compliance with applicable health regulations. This controlled method allows for a consistent product to be supplied throughout the year. The grading 3-12 indicates the size of this selection and stands for uniform quality and structure.
