Sevruga is one of the highest priced varieties of caviar, eclipsed in cost only by the Beluga and Ossetra varieties. It is harvested from the Sevruga sturgeon (Acipenser stellatus) native to the Caspian Sea, and may be distinguished from its more expensive cousins by the size of the eggs, which are generally smaller.Sevruga is the smallest of the caviar-producing sturgeons. It can grow as far as 150 lbs. in weight and 7 feet in length. It is native to the Black, Azov, Caspian and Aegean Seabasins.Because the Stellate sturgeon is the most common and reproduces more quickly, this makes Sevruga caviar the most commonly found of the sturgeon caviars, and the most inexpensive of the three main types of sturgeon caviar – Beluga, Osetra and Sevruga. It’s calculated that about half the caviar production comes from Sevruga. Sevruga caviar eggs are a pearlescent grey, and smaller in size than other sturgeon. The flavor is more pronounced than other varieties, often described as saltier, but it can vary depending on the origin of the fish. The caviar is packaged and sold in red tins.
Ossetra (also Oscietra, Osetra, or Asetra) caviar, is one of the most prized and expensive types of caviar,(eclipsed in price only by Beluga caviar). It is obtained from Ossetra sturgeon which weighs 50-400 pounds and can live up to 50 years.Ossetra caviar varies in color, from deep brown to gold. Lighter varieties are more sought after, as they have the richest flavor and come from the oldest of sturgeon. Golden Ossetra is a rare form of Ossetra caviar, and is golden-yellow in color with a very rich flavor
Beluga caviar is caviar consisting of the roe (or eggs) of the beluga sturgeon Huso huso. It is found primarily in the Caspian Sea, the world’s largest salt-water lake, which is bordered by Iran and the CIS countries of Azerbaijan, Kazakhstan, Russia, and Turkmenistan. It can also be found in the Black Sea basin and occasionally in the Adriatic Sea. Beluga caviar is the most expensive type of caviar.
