We only use the freshest butter for the production of our Attilus caviar butter. The shelf life is still at least 10 days from the delivery of your order. Like our caviar, the caviar butter should be stored in the coolest part of your refrigerator. Further details on storage and shelf life can be found on the tin. You should enjoy the caviar butter within 24 hours of opening the vacuum jar. During this time, the can must also be stored in the refrigerator.
