Austern reach their full flavor after being out of the water for between +3 and +7 days. An oyster that has just come out of the water will be less tasty than an oyster that has been out of the water for several days.
It is possible to open the Austern two to three hours before eating them. However, you must put the cover back on the oyster so that it does not dry out.
We recommend pairing Austern with dry white wines.
