The Caspian Sea & Caviar: A Story of Sturgeon, Luxury & Survival

The Caspian Sea—Earth's largest inland water body—is the historic and biological heart of the world's finest caviar (sturgeon roe).

The Sturgeon Species

• Beluga (Huso huso): Largest, rarest, most prized. Up to 1,500 kg, 100+ years. Caviar: large, pearlescent grey. Critically Endangered.
• Ossetra (Acipenser gueldenstaedtii): Medium. Caviar: nutty, golden-brown. Endangered.
• Sevruga (Acipenser stellatus): Smaller, more abundant. Caviar: smaller, grey-black, intense. Critically Endangered.

Why Caspian Caviar Is Unique

The Caspian's specific salinity (1.2–1.3%), temperature cycles, mineral content, and unique plankton/food web create roe with unparalleled texture, flavor complexity, and "pop." Centuries of Persian, Russian, Azerbaijani, Kazakh tradition refined harvesting/processing (malossol—light salt).

Crisis & Conservation

• Overfishing: Post-Soviet collapse (1990s) triggered uncontrolled poaching.
• Habitat Loss: Dams (Volga) block spawning; pollution; water extraction.
• CITES Ban (2006): Halted wild caviar trade. Strict quotas now.
• Aquaculture Shift: Farmed sturgeon (globally) now supply >95% of legal caviar. Caspian wild stock recovery is slow.

Current Status

Wild Caspian caviar is virtually absent from legal markets. Farmed "Caspian species" caviar (from Italy, France, China, Uruguay, Israel, etc.) dominates. True wild Caspian caviar remains the ultimate benchmark—an endangered legacy of a unique sea.
