B stands for:

Every Caspian Sea fisherman dreams of catching a great Beluga! As lucky as finding a diamond in the desert. The Huso Huso is the largest of the sturgeons, measuring up to 6 meters! It is the only carnivore of its kind. Its weight may vary from 100kg to 1000kg. It is also the rarest and most difficult fish to catch in the Caspian Sea, as it lives at great depths.

The Beluga is an anadromous fish, meaning it swims up from the sea to spawn in freshwater. The eggs can make up 25% of its weight! Females are not fertile until they are 25 years old, and do not necessarily spawn every year. Like most sturgeons, the Beluga can keep its roe for more than one season, if conditions and temperature are not conducive to spawning.

In fish farming, this is a very difficult fish to breed, requiring the know-how of professionals to work on its adaptation and maturity. From Beluga born in the Danube, farmed Beluga is rare. Today, very few farms breed this species, as it takes at least 15 years for the fish to give their first roe.

Back in the days of wild Iranian caviar, Beluga caviar was distinguished by the following colors:
Beluga triple 0 (000): large, light-colored grains
Beluga double 0 (00): medium gray grains
Beluga 0: the smallest dark-gray grains

Because of its impressive size, its roe is quite large and creamy. Varying in color from light to dark gray, they have a very thin membrane. The roe bursts easily on the palate, offering an unrivalled length on the finish, with delicate buttery notes. Unique, Beluga caviar remains the most prestigious caviar.
