Fresh live Kumamoto oysters (Crassostrea sikamea) are a premium Pacific oyster variety prized by shellfish enthusiasts worldwide. This 18-count pack features whole, live oysters in the shell, farm raised for consistent quality and flavor.
Kumamoto oysters are celebrated for their small to medium size and distinctively deep, bowl-shaped cups that hold more meat than flat-shelled varieties. They are known for their delicate, mildly sweet flavor with a clean briny finish and subtle notes of cucumber and melon — a profile that makes them one of the most beginner-friendly oysters available. The shells are rough and irregular, with a greenish-grey exterior typical of Pacific oysters.
Farm-raised Kumamoto oysters are typically sourced from the pristine, nutrient-rich waters of the Pacific Northwest and Northern California, including regions such as Humboldt Bay and Puget Sound. Sustainable aquaculture practices allow these oysters to feed on natural phytoplankton, contributing to their clean, nuanced flavor. They are best enjoyed fresh, served raw on the half shell with a squeeze of lemon, mignonette, or cocktail sauce, and pair exceptionally well with sparkling wines and champagne. They can also be grilled, baked, broiled, or fried.
Consuming raw or undercooked shellfish may increase the risk of foodborne illness. Keep refrigerated and consume within 5–7 days of purchase. Discard any oysters with open shells that do not close when tapped.
