Caviar has always been the delicacy of aristocrats and sophisticated gourmands. Even though nowadays you can buy black or red caviar in many stores – they are nowhere near a match to the real thing. There are more than 400 species of sturgeon in the world but only three of them – Beluga, Oscierte, Sevruga (Huso Huso, A gueldenstaedi, A sellatus – in Latin) which inhabit the Caspian Sea, the Sea of Azov and the Black Sea are used to obtain caviar.
