Cultured Onset Oysters

Our Onset Oysters are grown in Bourne Cove where natural spring waters flow into the cove and combine with the cool, clear saltwater of Buzzards Bay. These waters produce a sweet, briny Onset, a taste that people have come to love.

Our farm is located in Wareham, Massachusetts on the waters of Buzzards Bay near the Cape Cod Canal. The farm-raised oysters from Wareham and Onset have been shipped all over the United States, and our oysters are known for their quality and flavor.
