Arcachon
The Bordelais oyster — mild, mildly iodine, and eaten with rye bread and merguez on the lagoon's oyster-village jetties. France's second-largest basin and its most distinctly local oyster culture.
Cotuit
The sweeter side of Cape Cod — grown in Cotuit Bay's warm, protected waters with lower salinity than Wellfleet. Creamy, approachable, and the Eastern that wins over guests who find the bay's famous high-brine oyster too aggressive.
Hiroshima
Japan's dominant oyster — 60% of national production, large and meaty, grown in the warm sheltered waters of Hiroshima Bay. Sweet, umami-heavy, and built for cooking as much as raw service.
Katama Bay
Martha's Vineyard's shallow coastal lagoon Eastern — sweet, low-brine, and shaped by one of the East Coast's most unusual growing environments, where barrier beach breaches periodically connect a warm lagoon to the open Atlantic.
Setúbal / Ria Formosa
Portugal's two Pacific oyster growing environments — the cold Sado Estuary near Setúbal and the warm Algarve lagoon system of the Ria Formosa — producing Atlantic-influenced and Mediterranean-adjacent character from the same species in the same country.
Taranto
Italy's oldest oyster growing site — the ancient Mar Piccolo of Taranto, a near-enclosed Puglian tidal sea producing warm-Mediterranean Pacific oysters with high iodine character and the sweetness of a very sheltered, very warm growing environment.
Bouzigues
The French Pacific that breaks the mould — grown in the warm Mediterranean Thau Lagoon, with aggressive iodine and brine that has nothing in common with Breton or Norman production.
