What Experts Say

Across 10 sources, tasters describe this oyster as:

Unique notes: pickled-cucumber, horseradish, slate, buttery, mineral

"A great oyster from Eld Inlet. Oysters in Eld grow fast, fat, and creamy-sweet, and Chelsea Gems are no exception. They come to market at the extraordinarily tender age of five months, by which time they are petite three-inchers with very deep cups, due to all the natural tumbling. Inside is a little fella with all the sweetness and low salinity of other South Sound oysters but none of the low-tide flavors common to the beach-cultured varieties."

"Stunning little tumbled Pacifics with a mouthwatering pickled-cucumber brine to them. The white, black, and purple stripes on the deeply scooped shells make them feel like jewelry (or Baltimore Ravens swag). Some seasons, the meats can be a little thin and watery, but the flavor is all there."

History & Background

Chelsea Gem oysters were created in 1987 by Chelsea Farms as the original tide-tumbled oyster. John Lentz developed the first tide tumbling bags for cultivation, an innovative method that suspends oysters in bags by buoys in the water, creating constant tidal action that shapes the shells and develops unique flavor.

Chelsea Farms is well-known throughout the West Coast for the Chelsea Gem, their flagship oyster. The farm grows shellfish on Eld and Totten Inlet in South Puget Sound and has become a working model of environmental stewardship. Eld Inlet has been considered one of the 'Grand Crus' of Pacific Northwest oysters for more than a century.
