Caviar is the eggs (or roe) of female sturgeon, a “fossil” fish “化石”魚 living in coastal waters, rivers and lakes in the Northern Hemisphere.

Most of the world’s caviar comes from sturgeon of the Caspian Sea, an inland sea located between Iran and Russia. Three species of sturgeon produce most of the world’s caviar:

  • beluga sturgeon produces beluga caviar
    Beluga caviar is the world’s most expensive caviar, next to exceedingly rare Sterlet. Its roe is very large, ranging in color from black to pale grey, and has a smooth, buttery flavor. Fewer than 100 Beluga sturgeon are caught each year.
  • Russian sturgeon produces osetra caviar
    Osetra caviar consists of medium-sized eggs, ranging in color from dark brown to light grey and even golden brown. Many Gourmand(美食家) prefer Osetra’s nutty, slightly fruity flavor over Beluga.
  • stellate sturgeon produces sevruga caviar
    Sevruga caviar is the smallest roe of the three main caviar varieties. More plentiful than the other two, it is also the least expensive. Its roe is black to very light grey in color and, like Beluga, it has a buttery flavor, but saltier, richer, and more intense. It’s unique flavor is highly valued.


Sturgeon is the common name for the 27 species of fish belonging to the family Acipenseridae. Their evolution dates back to the Triassic some 245 to 208 million years ago. The family is grouped into four genera: Acipenser, Huso, Scaphirhynchus and Pseudoscaphirhynchus…..

Sturgeon can take from six to 25 years to reach sexual maturity and females of many species reproduce only once every three to four years. This means that sturgeon have fewer offspring over a lifetime than fish that reproduce at an earlier age and more frequently.

Many populations of sturgeon and paddlefish migrate through the waters of different states and countries, often resulting in a patchwork of different catch levels, season and size limits, and other management measures. Many of the world’s most imperiled sturgeon populations live in politically and economically unstable countries, further hampering effective management.

Caviar varieties produced from sturgeon and paddlefish farmed in the United States and Europe offer excellent taste and are environmentally sustainable. Unique roes from farmed trout and wild Alaska salmon are also better choices.

Countries control Caspian Sea sturgeon fishing and caviar production:-
Russia , Kazakhstan, Azerbaijan and Iran.

It is necessary killing the sturgeon to retrieve the caviar. Although on some sturgeon farms have developed a method for performing cesareans, allowing eggs to be removed without killing the fish. However, this practice is largely limited to the artificial reproduction and restocking efforts of Caspian hatcheries and has not been developed for the international caviar trade.

Countries of significant consumers of Caspian caviar
USA, European Union, Switzerland and Japan are the major importers of Caspian caviar. There is also a domestic market for Caspian caviar in Russia, much of it of an illegal nature.

Caviar is processed, salted fish roe, eggs. There are several caviar types and many varieties of fish that contribute to this ancient gourmet treat.

Rating of Caviar
Fine caviar is rated according to…

  • the size and color of its roe
  • its method of processing

Color is designated by…

  • 000 for light caviar
  • 00 for medium
  • 0 for dark

Very light or golden roe is also designated ‘Imperial’ caviar or ‘Royal’ caviar, and was once reserved only for royalty.

The best caviar is commonly understood to be sturgeon caviar, with the largest roe and the lightest color. Expensive caviars are not priced by taste, but rarity.


Almas – the Most Expensive Caviar in the World
The white eggs are obtained from specimens more than 100 years old. As the sturgeon get older, their eggs are more elegant, smooth, aromatic and delicious with a spongier texture. The most expensive is the exclusive variety called Almas, which in Russian means “diamond”, and its price is almost as high as that of the precious gemstone.
