All about bouchot mussels

How to recognise them

These little molluscs have a bluish-black shell and yellow-orange meat. Low in calories and rich in iodine, mussels are the ideal dish for filling up on protein, calcium and iron. Bouchot mussels are one of many types of mussel. Brittany is known for its “bouchots”, which have an inimitable taste and recognised quality.

Where are they produced?

In Brittany, the production zones for bouchot mussels are mainly in the Breton part of Mont Saint-Michel bay, Saint-Brieuc bay, Brest bay and in the Vilaine estuary near Pénestin.

When to eat them?

The season for mussels is from July to January. Brittany is the second largest mussel farming region, behind Normandy.


How are they farmed?

Mussel farmers catch larval mussels naturally on ropes made of natural and biodegradable fibre. They are then wound around wooden stakes, also called bouchots. This way, the mussels are out of reach of crabs and other predators. Each bouchot stake can hold up to 80 kg of mussels. The shell of the bouchot mussel is at least 12mm thick and no more than 8 cm long. It does not contain sand or parasites.

How do you cook them?

In a creamy sauce, on a plancha, stuffed, cold, with escabèche sauce: there are so many ways, it’s entirely up to you!  Use around 500 g per person for a main course. When purchasing, choose shells that are closed or that respond to finger pressure. You need to clean them to remove the byssus (a filament that allows the mussel to attach itself to hard surfaces) and any small shellfish that might have taken up residence on their shell.  They can also be bought already cleaned, in this case they are “ready-to-cook”. Then, put them in a saucepan with an onion, parsley and white wine for the “marinière” version. The mussels open within 5 minutes. Just eat with your fingers or a shell!


How to keep them?

Uncooked mussels can be kept for 48 hours in the refrigerator. Already-cooked mussels can be enjoyed as tapas the following day.



To be sure of their freshness, one tip is to put them in water for 10 minutes. Any that float up to the surface must not be eaten.

Events around mussels

Did you know?

How did Bouchot mussels come about?

This form of farming is down to the Irish man, Patrick Walton, who in 1235 noticed that poles planted in the sea were spontaneously covered with mussels. The poles were arranged to form a wooden fence, which he called “bout” and “choat”. The bouchots get their name from this invention.
