BELUGA CAVIAR:
The most prestigious and renowned due to the time necessary to harvest it, the Iranian Beluga caviar comes from the wild species Huso Huso, raised in our fish farms along the Caspian Sea. This caviar is the strong point of our company since we are the main partners of this fish farm. The basins are filled with the waters of the Caspian Sea, and the sturgeons can find all the necessary nutrients, providing the caviar with a taste, color and texture that resemble very strong the wild caviar. The grains are loose and the color is light brown to gray, giving it a small golden effect. The female beluga sturgeon takes up to 18 years to mature and produce eggs. The most highly priced caviar of all is Beluga.

Beluga roe is the largest of 3 types and is the rarest. It has a delicate skin, considerable texture and a visible eye in the middle of each individual egg. Typical Iranian beluga caviar are lighter in color and a subtle creamy flavor with a hint of sweetness on the palate.
Fish farmers around the world begun importing eggs and fingerlings of Caspian sea sturgeon to raise in their regions. Fish farmers mention the fact that sturgeons travel long distances and vary in flavor regardless of where ending up in Caspian waters.
Most farms access natural resources available in their area, but keep a controlled environment for better consistency, a long time mark of quality caviar processing.
The very limited supply of these caviars from the Caspian sea are found in Europe and other regions either on the open or black markets.

Iranian Asetra (also known as Asetra, Ossetra, or Oscietra) is a highly revered sturgeon which produces among the best tasting caviar is the world. As price of caviar is not always based on its taste, the asetra is a better value with a rich taste.

SEVRUGA CAVIAR:
Sevruga are generally smaller and mature earlier than the Osetra after only 7 years, and given their early maturation.
Sevruga in the wild may grow to lengths of up to 5 feet and at a weight of close to 150 lbs. They are most distinguished by their long snout and elongated form. The Iranian sevruga caviar offers rich flavors from the most sought after Caspian sea harvests.
Iran along with Russia has historically been at the top of the most cherished caviars in the world. Intense flavor of the sevruga sturgeon’s caviar is recommended and noted to be better than the most prized beluga sturgeon’s. Sevruga roe is the least rare of the three. It has a delicate skin and its color ranges from light to dark gray. Since they are the least rare, they are also the least expensive, thus, sevruga roe is the most popular out of the three prized types of caviar.
