If you want to maintain the integrity of your caviar, it should never be frozen. Caviar is far too delicate to freeze. If the caviar is frozen it will loose its subtle properties such as its texture and pop, however, the taste of the caviar will be preserved. But remember, half the fun of caviar is experiencing all the nuances, including the texture, so we strongly urge you not to freeze your caviar. The whitefish, trout and salmon caviars, on the other hand, can be frozen for later use. We recommend that you do not freeze, defrost and refreeze the caviar.
