Flat oyster: Belon, Fine, Spéciale
The Ostrea edulis ecosystem and its historic appellations.
Updated on May 7, 20261 min readhuître plateBelon
The flat oyster — Ostrea edulis — carries a distinct world of appellations from the cupped oyster. OstraOS natively handles the historic qualities of this species, from the prestigious Belon to its cousins Fine and Spéciale flat.
Three flagship qualities
- Belon: traditional appellation from the Belon river in Brittany, one of the most renowned flat oysters.
- Fine flat: standard flat-oyster quality after purification.
- Spéciale flat: premium quality, with stricter specifications.
- Organic: rearing under the applicable organic standards.
Unlike its cupped cousin, the flat oyster usually does not go through Marennes-Oléron claire affinage. Its purification follows the same regulatory frame as any shellfish species, with mandatory transit through purification before commercial release.
Good to know
International flat-oyster qualities (Galway Native in Ireland, Colchester in the UK, Bluff in New Zealand) are also supported in OstraOS for exporting or importing operations.
