Main areas

Good to know

Where the Pacific oyster is at its best in winter, the rock oyster comes into season in summer, which is unusual. Its spawning is spread over a long period, so it does not thin out in the warm months. It grows two to four years longer, giving a larger shell, more meat and a deeper flavour.
