Ossetra (also Osetra, Oscietra, Osetrova, 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 the Russian sturgeon (Huso gueldenstaedtii), which weighs 50-400 pounds (22.6-181.4 kg) and can live up to 50 years.

Ossetra caviar varies in color from deep brown to gold. Lighter varieties are more sought after,
