Is a quiet village on the South Shore of Cape Cod named after the local Indian Chief of the Mattacheese tribe. Wianno Oysters are grown in the crystal clear waters of Cape Cod Bay and Nantucket Sound. Always harvested by hand, Wianno Oysters have a pearl white interior shell and a distinctive exterior that denotes a superior quality New England Oyster. These plump, succulent oysters have the distinct sweet and briny “Wellfleet” flavor.
