Cupped oyster: Fines, Spéciales, Pousse en Claire

The cupped oyster — Magallana gigas — carries the most iconic qualities of the trade. OstraOS natively supports the whole Marennes-Oléron ecosystem, from the most discreet claires to the most demanding appellations.

Claire-affinage qualities

• Fine de Claire: affinage in Marennes-Oléron claires, guaranteed meat ratio.
• Spéciale de Claire: extended affinage, more demanding meat ratio.
• Pousse en Claire: the longest affinage, the strictest stocking density, premium quality.
• Standard: cupped oyster without claire affinage, ready after purification.
• Label Rouge, Organic, PGI Marennes-Oléron: complementary qualifications handled as labels.

For each quality, OstraOS knows the minimum affinage duration, the maximum stocking density and the expected meat ratio. You stay in charge of those rules: they are fully configurable in the traceability settings.
