STURCAVIAR should bekept at 26-35 F. If properly stored in the fridge, it will last between 4-6 weeks if the container is unopened. Once the tin has been opened, the caviar will stay fresh between 3-5 days which can be monitored by the smell and looks. Air is caviar’s largest enemy. Ideally it isbest to purchase caviar in smaller containers, in increments thatwill be consumed in a single seating. If you have purchased morethan you are serving, the remaining caviar should be spread flat gently with a mother of pearl or plastic spoon, taking care not to break any of the eggs. Then you may cover it with plastic wrap by pressing down gently on top so no air space remains between the eggs and cover it with a lid. The remaining caviar shouldbe consumed within the next 3-4 days.
