Caviar is one of the most expensive dishes in the world thus before buying people get curious about its life.

So that the dish does not go bad before they have it, as it will be a total waste.

Even though the dish is entirely delicious, you can finish them in one go.

However, people still think that do caviar go bad or how long it can be stored.

Even though you pay so much for the dish, they still have a small shelf life.

Therefore while having it, one should be cautious as bad caviar can cause food poisoning.

What is Caviar?

This is the roe from the sturgeon family of fish and is eaten raw as an appetizer.

Back then, these roes came from Caspian and black seas, but because of overfishing now, their production is done all around the world.

It is available in different varieties such as osetra, sevruga, beluga, Kaluga, and starlet.

Sturgeon fishes move from saltwater to fresh ones; the caviar tastes like ocean water but is a little salty.

However, the taste of roe will vary as per the variety of caviar.

One can find caviar in two types of texture.

One is firm and large, which is more expensive.

The other is not fine in texture and has imperfect formation, so they are less expensive.

Caviar comes in pasteurized and unpasteurized forms, but pasteurized ones are more likely to go rancid and cause foodborne illnesses.

How Long Does Caviar Last? Does Caviar Go Bad?

As caviars are of different types, thus they have distinct shelf lives.

Besides, storing measures can also help in increasing these eggs’ shelf life.

All the chilled caviars except premium sturgeon caviar can serve for 18 months if you provide a recommended temperature.

When anyone buys a tin of these eggs, they contain labeled date and storage measures.

So if anyone follows those instructions, they can preserve your caviars for an extended period.

If we talk about the frozen salmon caviar stored in the refrigerator after it thawed, then one can have them for up to 10 days.

The premium sturgeon egg has no preservatives; thus, whether you refrigerate them or not, they will only serve you for up to ten days.

After opening the tin, the eggs will not be fresh for too long; thus, one must finish them off within a short period.

The eggs will be fine until these are unexposed to bacteria; however, once the caviar is opened, they will only last for one to two weeks as they become prone to bacteria.

How to Tell if Caviar Has Gone Bad?

  • Foul Smell .

While having old stored eggs, one must be careful and look for bad signs.

So you can try to smell it, as fresh caviar has a pleasant smell.

However, this pleasant smell will not last long and begin to fade away as the eggs go bad.

Therefore if after smelling, the scent feels worse and unpleasant, then you should avoid having the caviar as it has gone bad.

  • Changes in Color .

Everyone knows that fresh caviar has yellow or grey color, but after storage, it’s not safe anymore.

If that has happened with your eggs, too, then they have gone bad.

That is because these eggs only shift their color as bacteria begin to develop in them.

If anyone keeps the caviar stored for a prolonged period, then it will turn black, and it is an indication that one should discard them.

  • Put the Eggs in the Water.

Another way to find bad caviar is to put them in water and see if they sink or float.

When the eggs are fresh, then they will sink to the bottom.

However, in case they have gone bad, then they will float on water.

This will give you a clear indication of whether your caviar is good or not.

Sometimes eggs are bad since you bought them, so by putting them in the water; you can see their condition.

How to Store Caviar?

  • Store at a Cool Temperature.

These eggs are delicate and highly perishable; thus, it would be better to keep up with their storage.

If you store caviar at a high temperature, it gets a bacterial infection.

Therefore one must be sure they are storing the eggs at cool temperatures.

The ideal temperature for refrigeration lies between 28 to 32 degrees Fahrenheit.

You should keep the eggs out of the refrigerator for 10 to 15 minutes before serving them.

  • Leftover Caviar.

No matter if they are opened or leftover eggs, you must keep them refrigerated.

These should be kept in the fridge as soon as anyone opens their tin.

However, the leftovers will not last if you store them directly in the refrigerator; thus, you must add a plastic wrap to protect them from strong smells and other food items.

  • Serve With Dry Ice.

At the time of serving, people must serve it in its original tin in a bowl of ice.

That is because if you keep it at room temperature directly from the refrigerator, its temperature will become unstable and go bad.

So it would be better to add crushed ice to stabilize its temperature.


Storing caviar is relatively easy if you follow all the measures correctly.

If anyone has unpasteurized eggs, they should keep them unopened if they do not want to have them immediately.

That is because their unopened pack can be stored for up to 4 weeks but opened tin will only last 48 hours.

As caviar goes bad too quickly, thus one must look for the earlier mentioned bad signs before having old stored caviar.
