In order for caviar to be stored as long as possible, it must initially be fresh 
After opening, even in the refrigerator, caviar can lie for a certain time - as a rule, no more than 3 days 
There is an option to purchase black caviar not in a jar, but by weight 
When defrosting, instead of expensive caviar, an incomprehensible porridge with a fishy smell may appear on the festive table 
At home, black caviar is optimally placed in a glass container.
