Caviar is a luxurious and expensive delicacy made from sturgeon roe. Beluga caviar, derived from the beluga sturgeon, is one of the most exclusive types of caviar. Due to overfishing, wild-caught beluga sturgeon is nearly extinct, but farm-raised beluga caviar is still available. It has a complex, savory, and slightly salty flavor, and the eggs are large and have a dark color. Osetra caviar comes from the osetra sturgeon and is more readily available and affordable.
It has a wide range of colors and a savory flavor with notes of nuts and butter. Beluga caviar is more expensive due to its rarity and flavor complexity.
