Genuine caviar refers to Beluga (Huso huso), Osetra—with two Osetra varieties, Russian (Acipenser gueldenstaedtii) and Persian Osetra (Acipenser persicus)—and Sevruga (Acipenser slellatus). All three types of sturgeon originate in the Caspian Sea.
The Caspian Sea’s Beluga sturgeon lives predominantly in the wild and only a small number can be caught from the Sea annually, making it an extremely rare product. There are only two types of genuine Osetra caviar, as noted, Russian and Persian, and Russian Osetra caviar is one of the world’s most prized and exclusive luxury foods. It is known by experts for its versatility of flavor, size and color.
