What’s the best way to store caviar before and after it’s opened?

Once you’ve received your caviar you may immediately want to enjoy it. Or you may choose to save it for a little while. If that’s the case you need to make sure that it is properly stored to keep it from spoiling. If you have Malossol caviar you need to get it into the refrigerator quickly and keep it from being exposed to the air as much as possible. This will give you between four and six weeks to enjoy it.
If you put your unopened caviar in the fridge until you’re ready to enjoy it this will give you the best quality. The vacuum seal is essential and keeping it intact preserves the caviar the way it was meant to be. This is also a good reason to opt for small containers that you can finish within a short period of time rather than larger containers.
Once you open the caviar make sure that you put any leftovers back in the fridge quickly. Reattach the lid to the container as tightly as possible to keep out as much air as you can. You can even use plastic wrap under the lid of the glass jars to make sure you’re keeping out even more air.
The vacuum seal is the best part of protecting your caviar, but the second-best thing is to keep your caviar at the right temperature of 26° to 36° F in a refrigerator. This will keep the quality as fresh as possible even after the caviar has been opened.

Can I freeze my caviar?

Freezing caviar is possible, and will actually increase the shelf-life to approximately a year. Keep in mind however that thawing the caviar will change the flavor and could soften the texture as well. If you freeze and thaw the caviar more than once it will continue to decrease in overall quality.
