Atlantic Ocean

Ireland

Ireland's cold, clean Atlantic bays produce two distinct oysters: the prized native flat (Ostrea edulis), with its intense, metallic complexity, and the widely farmed Pacific gigas, grown sweet and briny in the tidal estuaries of the west coast. Galway Bay, fed by the Clarinbridge and Kilcolgan rivers, is the spiritual home of the Irish oyster and its long-running autumn festivals.
