Bluff Oysters are the most prized oysters in the Southern Hemisphere — wild dredge oysters from the cold, deep Foveaux Strait at the bottom of New Zealand's South Island. Available only from March to August, they are eaten raw with nothing but a squeeze of lemon, the richest, most mineral oyster in the world. The Bluff Oyster Festival is a national event.
Bluff Oysters (Ostrea chilensis) are dredged from Foveaux Strait, the cold, rough channel between New Zealand's South Island and Stewart Island. The oyster fishery, based in the port town of Bluff at the very bottom of the South Island, dates to the 1860s. The season is strictly regulated (March to August), and the oysters are harvested wild (not farmed). The Bluff Oyster is legendary in NZ — smaller and richer than Pacific oysters, with a deep mineral taste and a firm, meaty texture. The annual Bluff Oyster and Food Festival in May draws visitors from across the country. They are eaten raw, with nothing but lemon, or lightly battered and fried.
A small, deep-cupped oyster, the shell encrusted with the Strait's marine growth. Slide it into the mouth: the flesh is firm and meaty (not flabby), the taste is intensely mineral and briny, with a copper-sweet richness that fills the whole palate. It is the most powerful oyster in the world. A squeeze of lemon, a swallow, and you understand the festival.
Bluff oysters are dredge oysters (not rock/ Pacific oysters) — they grow wild on the seabed of Foveaux Strait at depths of 20-50 meters, in water temperatures of 8-12°C. The cold, the depth, and the Strait's strong currents give them their firm texture and intense mineral flavor. They are eaten raw and whole (the entire oyster, including the liquor), with only a squeeze of lemon. The season is short and strictly managed; the oysters are shipped live across NZ within hours of harvest.
Variations
Some batter and fry them; some grill them with garlic butter; some add a dash of Tabasco; the traditional way is raw with lemon only.

Watch outEat raw within minutes of opening — a fresh Bluff smells clean like the sea; any sour or off smell means don't eat it.
