What is the Shelf Life of Caviar?

The shelf life of caviar is contingent on a variety of factors, such as the size of the tin, and the storage method. 

Vacuum-sealed and refrigerated unpasteurized caviar has a shelf life of three to twelve months. Once the tin has been opened, the shelf life drops to six months.

Unopened, pasteurized caviar can remain on the rack for up to six months. Once opened, caviar should be enjoyed within a few days.

To preserve its freshness, caviar should be refrigerated at a temperature just below freezing, but not completely frozen.

To preserve the caviar’s quality and freshness, it is essential to adhere to the manufacturer’s storage instructions.

Factors that Affect the Caviar Shelf Life

Have you ever wondered why some caviar expires quickly while others can stay fresh for months? There are several factors that affect the shelf life of caviar.

One of the most important is the temperature. Any temperature variation can cause bacterial growth and spoilage.

Another factor is the quality of the caviar. Good quality caviar has a higher percentage of fat, which acts as a natural preservative.

Packaging also plays an essential role in caviar longevity. Vacuum-sealed packaging can help extend the shelf life to a few months, whereas open jars need to be consumed within a week or two.

It’s important to understand these factors to ensure the longevity of your caviar and fully enjoy its exquisite flavors.

Storing Caviar Properly for Optimal Shelf Life

If you’re a caviar lover, you know that this delicacy deserves proper storage. Storing caviar properly is crucial for optimal shelf life and maintaining its quality.

The last thing you want is to open your jar of prized caviar and find it has gone bad.

To prevent this from happening, always ensure that your caviar is stored at a constant temperature of 28 – 32 degrees Fahrenheit. Avoid freezing it, as it can damage the texture and flavor.

It is essential to store caviar in an area that is shielded from direct sunlight and to avoid exposing it to air.

Use a clean utensil to scoop out caviar to avoid contamination.

After using the caviar, the jar should be securely resealed immediately to prevent air from getting inside.

If you follow these easy instructions, you will be able to keep your caviar fresh and full of flavor for an extended period of time.

How to Tell if Caviar Has Gone Bad?

There are several ways to determine whether caviar has gone spoiled.

The scent is one of the most evident indications when caviar has gone bad. The smell of spoiled caviar can be overpowering and offensive.

The caviar’s color can also shift from yellow to forced black and possibly even become a deeper shade of black. A solid texture and glossy sheen are characteristics of fresh caviar.

The caviar may have gone bad if it appears bland or mushy. Put some caviar in water and check to see if the eggs float to determine if the caviar has expired.

Caviar that is spoiled or has gone bad will rise to the top, whereas fresh caviar will sink to the bottom. If there is any egg caviar that is floating in the mixture, it is recommended that the entire batch be thrown out.

Once the can is opened, the caviar will only keep its quality for two to three days, and even then, only if it is carefully preserved in the refrigerator.


As you can see, caviar is an exquisite treat that should be handled with caution. With proper storage and handling, its shelf life can increase for up to a year – even if it’s not stored in the refrigerator.

However, always check your caviar for signs of spoilage before trying it. Even after its expiration date, caviar may taste good if it’s properly stored and refrigerated once opened.
