Also spelled Ossetra, Oscietra, or Asestra. This caviar consists of medium-sized eggs, ranging in color from dark brown to light grey and even golden brown. Many prefer Osetra's nutty, slightly fruity flavor over Beluga.

The rare golden caviar (or Imperial caviar), comes from Acipenser guldenstaedti. These sturgeon range in size from 40 to 160 pounds. Although the golden caviar is highly prized, the eggs of this species are often more brownish in color. The caviar has a distinctive nutty flavor.
