Beluga caviar is a luxury delicacy made from the roe of the Beluga sturgeon, a large fish found primarily in the Caspian Sea. Known for its large, soft eggs, Beluga caviar has a delicate, buttery flavor and a smooth texture. It is often considered the most prestigious type of caviar due to its rarity and the lengthy process required for harvesting. The production of Beluga caviar is highly regulated, as the Beluga sturgeon is classified as a threatened species. This has led to restrictions on fishing and trade, making authentic Beluga caviar both expensive and sought after by gourmet food enthusiasts around the world.
