Siberian Sturgeon Caviar is a caviar derived from the Siberian Sturgeon, which is a part of the Acipenseridae family. The Siberian Sturgeon is most abundant in all of the major Siberian river basins that drain northward into the Kara, Laptev, and East Siberian Seas. The adult Siberian Sturgeon usually weighs around 65kg, but its size varies considerably throughout the various river basins of Siberia. Siberian Sturgeons commonly live up to 60 years in the wild. Males do not reach sexual maturity until 11-24 years of age, and for females it takes even longer: 20-28 years. Often the roe of the Siberian Sturgeon is mislabelled as “Osetra”; however, the Siberian Sturgeon is a separate species on its own.
The Siberian Sturgeon feeds primarily on a variety of benthic organisms, such as crustaceans and chironmid larvae. Because of habitat loss and degradation, the once-abundant population of the Siberian Sturgeon has been in rapid decline. Due to this, the majority of all Siberian Sturgeon Caviar is the product of farm-raised Siberian Sturgeon, with the main producer being France. However, the largest producers of Siberian Sturgeon meat are Russia and China.
Siberian Sturgeon Caviar can be brown, grey, or black, with a diameter over 2.8mm. The flavour is often described as being “pure” with a light aftertaste.
