Duxbury Oysters are an East Coast oyster from one of the Massachusetts & Rhode Island oyster appellations. They are cultivated in the cold, grassy, nutrient rich waters of Duxbury Bay, which is actually a small bay within Cape CodBay. The steady southwesterly winds help blow warm waters away and as a result the waters here are colder than Cape Cod Bay with the result that Duxbury Oysters do not go into spawn. But they act as if they are going to spawn by building up the fat and glycogen stores which carry other oysters through the spawning process. These extra stores of fat & glycogen gives Duxbury Oysters there plump, buttery texture and taste.
