Oyster season: six British oyster farms to know

Article, 27 October 2026

Autumn is when oysters come into their own. Britain's native oyster is traditionally eaten only in the months with an "r" in their name, September to April, because it breeds in the warmer months and is at its best once the water turns cold. Rock oysters are farmed all year, but they are at their plumpest now too.

Every farm below is on Earth & Ocean, with a link to its page, its own website and, where you can visit, a way to add it to a food trip.

Native or rock?

The native oyster is flat, round and slow growing, with a deep, mineral flavour. It is now rare in the wild, and growers and charities around the coast are working to bring it back. The rock oyster (also called the Pacific oyster) has a deeper cup, grows faster and tastes cleaner and creamier. It is the oyster most of us eat.

Lindisfarne Oysters, Northumberland

Colchester has been famous for oysters since Roman times. The fishery sits at Pyefleet Quay on Mersea Island and sells its oysters alongside lobster and seafood platters, so it makes a good stop on an Essex coast trip. See Colchester Oyster Fishery.

Porlock Bay Oysters, Somerset

A family shellfish farm on the Anglesey shore of the Menai Strait, with oysters and mussels to collect or have delivered. Halen Môn's saltworks is just along the shore, so you can make a morning of it. See Menai Oysters and Mussels.

Atlantic Edge Oysters, Pembrokeshire

Grown among seagrass beds in a Marine Protected Area, in Class A waters washed by strong Atlantic tides. Pembrokeshire oysters were given protected (PGI) status in April 2025, alongside Welsh gin and honey. See Atlantic Edge Oysters.

Opening and serving

Hold the oyster flat side up in a folded tea towel, push an oyster knife into the hinge and twist. Slide the knife under the oyster to free it, keeping the juice in the shell. Serve on ice with lemon, or a spoon of finely chopped shallot in good vinegar. Eat them the day you open them.
