Wellfleet, a picturesque town on Cape Cod, Massachusetts, is celebrated for its world-class oysters, each offering a distinct taste of the sea. These flavors aren’t just a matter of chance but are intricately linked to the unique characteristics of Wellfleet Harbor’s outflowing tidal areas. In this blog post, we’ll explore how tidal areas like the Herring River, Egg Island, Duck Creek, Blackfish Creek, Loagy Bay, and Silver Spring contribute to the varied and remarkable flavors of Wellfleet oysters.
