Unique notes: caviar, hazelnut, gamey, smoky, zinc, steel, brassy

"Medium, Metallic with a trace of caviar and hazelnut. This has the loudest flavor of the bunch. The wine equivalent would be a super Tannic Barolo. Complex."

About the Farm

wild harvest

History & Background

The European Flat oyster (Ostrea edulis) is the native oyster of Europe with a cultivation history dating back centuries. Once ubiquitous in European waters, it was nearly wiped out due to overfishing, pollution, and disease in the early 20th century. In the 1950s, it was introduced to the United States, particularly Maine, where it became known as the Belon oyster after the famous French river.

The European Flat is considered by many to be the 'Cadillac of oysters' and represents the pinnacle of oyster cultivation in European tradition. In places like Yerseke, Netherlands, and Mali Ston, Croatia, these oysters were historically cultivated on rooftiles in practices dating back centuries. The oyster has deep cultural significance in France, Ireland, and the UK.
