How long does caviar last? Caviar Expiry

Caviar has a very short shelf life, which means that it needs to be treated in very specific ways in order to keep the quality that you’re looking for. Processing, pasteurization, storage, and air content will all affect the length of time that your caviar is going to be good.

If you get unopened, properly refrigerated, non-pasteurized malossol, you’ll be able to keep it for approximately one month before it will start to spoil. If the container is pasteurized or if you put it in a freezer instead you’ll be able to keep it for up to a year. Keep in mind that once any of these containers are opened and air gets into them they will start to dry out. Within three to seven days they will start losing flavor and texture and won’t taste the way you expect.

If you’re looking for a longer lifespan you can take a look at pressed caviar, which is also required to be refrigerated. If it’s highly-salted it could be shelf-stable, which increases the shelf life and may even get you several years of life before it starts to spoil.
