Sturgeon Caviar

Caviar is the roe from Sturgeon (Acipenseridae). The best types of caviar are Russian Ossetra (also spelled Osetra or Oscietra), Kaluga, and Beluga Hybrid. Sturgeon caviar is an expensive luxury, but if you have had the privilege of having it, you know its worth is proven. Less expensive ikura (or Salmon roe), Trout roe, Bowfin, and Hackleback are often called "caviar;" however, food aficionados will tell you they are simply known as "roe."
