Beluga, the largest eggs, comes from the species Huso huso. Huso huso typically weigh 80 to 400 pounds when harvested and may weigh up to 2,000 pounds. 15 percent of its weight is eggs. The female Huso huso doesn't bear eggs until around 25 years old and may live up to 150 years. Beluga has a rich, creamy flavor and delicate texture. Its rarity, however, is what makes it the most esteemed of all caviars.

Beluga is the world's most expensive caviar, next to exceedingly rare Sterlet. Its roe is very large, ranging in color from black to pale grey, and has a smooth, buttery flavor. Fewer than 100 Beluga sturgeon are caught each year.
