What is Caviar?

It is called CAVIAR, the eggs of sturgeon fish that are destined for consumption in banquets and buffets.

They do not always come from the sturgeon, they can also be from other fish such as cod, salmon, lumpfish, among others, whose eggs are placed in black dye to look like Sturgeon. Since Sturgeon is a very rare and scarce species, caviar is really expensive, sturgeon fish farming has been developed, which is a way of producing it in captivity, bobtail in nurseries.

When they reach the fertile age, they are artificially inseminated and when the time is right, the eggs are extracted, cleaned, salted and packaged.

The best and most expensive CAVIAR is the one that comes from the countries on the Caspian Sea as Aserbaiyan, Iran, Russia, although there is caviar that comes from Canada, Romania, France, not as expensive as substitutes, red caviar or salmon and other fish different from Sturgeon.

How to buy Caviar.

It is advisable to buy the CAVIAR packaged in glass containers and not in cans because they can alter its flavor.

Classification, characteristics and quality.

The caviar is classified according to the size of the egg, the firmness of the grain and its flavor.

After cataloguing them based on the above characteristics and if they are suitable, it is passed to classify them according to the color. 

If they have very clear tonality, they are called Imperial and if it is darker they are called Royal. The inferior to these two is called Classic. Any of these categories are of great quality.
