Siberian sturgeon is mostly prized for its dark and glossy caviar. As the name suggests, Siberian sturgeon (Acipenser baerii) is mainly associated with Siberian rivers, lakes, and seas. The population is listed as endangered on the IUCN Red List, and caviar is mostly harvested from farm-raised sturgeons.
This caviar ranges from dark brown to black, and it typically has medium-sized, glistening beads. The flavor is earthy, nutty, buttery, and subtly sweet. It can be served on its own—preferably well-chilled—or paired with simple dishes such as the classic combination of blini pancakes and crème fraiche.
By the 1990s, the number of sturgeons significantly declined, mostly due to overfishing and pollution. Several countries now ban the sales of wild caviar for various environmental and political reasons. At the same time, aqua farms became the future of caviar trade.
