Island Creek vs Wellfleet
This is a Massachusetts family feud: two Eastern oysters (Crassostrea virginica) from the cold waters of Cape Cod, both equally briny at a brininess of 4. The Island Creek, from Duxbury Bay, is the richer and more complex of the two — a medium-to-large oyster (2-4 inches) with briny, buttery, and sweet primary flavors, a sweetness of 4, and a long, sweet, mossy finish with distinctive lobster-stock savoriness. The Wellfleet, from Wellfleet Harbor, is leaner and cleaner: a medium oyster (2.5-3 inches) with briny and clean primary notes, a lower sweetness of 2, and a clean, slightly sweet finish. Both share the same salinity, species, and mineral backbone (3 out of 5), so the real divide is depth of flavor — the buttery, layered Island Creek versus the crisp, versatile Wellfleet.
