The Oysters

Graded, harvested to order, and grown by Shannon Oysters in the clean tidal waters of Poulnasherry Bay.

An honest, authentic oyster

No shortcuts, no messing about — just what the bay and a bit of patience can do.

Our Pacific oysters (Crassostrea gigas) are grown out on trestles in Poulnasherry Bay, turned by hand, and graded before they ever leave the yard. Clean Atlantic water, a strong tide, and time — that's the whole recipe. What you get is a plump, briny, genuinely authentic Irish oyster with a clean finish — grown the way it's always been done here, not rushed along for the sake of it.

From the bay to the grading floor

A look at how Shannon Oysters grades what comes off the trestles, from seed to a ready-for-market oyster.
