Caviar, sometimes called black caviar, is a luxury delicacy, consisting of processed, salted, non-fertilized sturgeon roe. The roe can be "fresh" (non-pasteurized) or pasteurized, the latter having much less gastronomic and economic value. Traditionally the designation caviar is only used for sturgeon roe from the wild sturgeon species living in the Caspian Sea, in most cases from Azerbaijan, Russia or Iran (Beluga, Ossetra and Sevruga caviars).
