Eastern oyster
Katama Bay from Edgartown reads bold Atlantic brine with sweet-salty mid-palate and velvety texture. Off-bottom tumbling in strong tidal currents deepens cups on this farmed Eastern line. A reliable Martha’s Vineyard raw-bar cup year-round.

How I serve it
On the half shell with minimal garnish — let the oyster speak.
What to watch for
Reject shells with ammonia or iodine off-aromas, broken cups, or milky liquor. Peak cups show deep brine with a clean, balanced finish.
My read
Bold brine — clean and versatile. A solid farmed eastern oyster.
What Are Katama Bay Oysters?
Katama Bay Oysters are farmed Eastern oysters from Katama Bay in Edgartown, Massachusetts. The bay sits on the south shore of Martha’s Vineyard. Signature Oyster Farm cultivates the line in off-bottom cages with tidal tumbling.
The stock is Crassostrea virginica raised through farmed, tidal upweller to bagged cage culture. Market selects typically measure three to three-and-a-half inches. Shells cup deeply from tumbling in strong tidal currents.
On the half shell the line reads Briny + Clean with salinity near 28 ppt. Sweet and salty notes build through the slurp with a rich, velvety texture. The finish stays clean and balanced without lingering metal.

How Did Katama Bay Oysters Get Their Name?
The Katama Bay name appears on tags tied to oysters grown in Edgartown, Massachusetts. That town sits on the south shore of Martha’s Vineyard. Buyers see the label on menus and shellfish tags across the Northeast.
Katama Bay is the trade label distributors and raw bars use for this oyster line. The word Katama comes from the Wampanoag language and means crab-fishing place. The label links the oyster to that Martha’s Vineyard bay rather than a single lease block.

Location
Katama Bay is located in Edgartown, Massachusetts, on the south shore of the island of Martha’s Vineyard. The bay opens on the eastern side of Chappaquiddick island. Cold Atlantic water flushes the lease sites throughout the tide cycle. For another New England Eastern cup with a distinct regional profile, see Cape Porpoise Oysters .
Deep waters and strong currents provide ideal growing conditions for Eastern oysters here. Salinity runs near 28 ppt in this Atlantic-fed embayment. That salinity shapes the bold, briny character chefs expect from the line.
Signature Oyster Farm works off-bottom cages in these tidal flows. Tumbling hardens shells and deepens cups before harvest. Year-round tags are common because the farm sells through Boston and island restaurants alike.
