Imperial Kaluga Hybrid Sturgeon Caviar

The Kaluga sturgeon is also known as the River Beluga. The Kaluga is one of the largest freshwater sturgeon species and Imperial Kaluga Hybrid caviar is obtained from a cross between the Kaluga and Amur Sturgeon species, as purebred Kaluga caviar is illegal in the USA.

Kaluga Hybrid caviar is a viable substitute for the prized Beluga sturgeon caviar, which comes from the endangered Beluga (huso huso) sturgeon. It also makes a more affordable substitute for the more expensive Osetra sturgeon (Russian sturgeon) caviar.

How do I compare gold color and black color caviar grains?

Kaluga and Osetra caviars are the two caviars that are graded on a color scale from black, to amber, to gold. The lighter the grain (gold), the older the fish, the more mature the ovaries, the larger the eggs, the more buttery, and the more prized they are, resulting in more expensive caviar. However, regardless of color, all of Stur Caviar's Kaluga and Osetra caviars have delicate tastes and high quality. Kaluga caviar is more popularly farmed and widely available than Osetra caviar, making it less expensive than the more prized, Royal Osetra caviar. If you're looking for a more luxury experience, be sure to check out our Siberian Sturgeon and Osetra caviars.

Why is caviar so prized?

Historically, royalty has feasted upon the luxurious and decadent caviar of Osetra and Beluga sturgeon species. Due to overfishing for their luxurious caviar, many species have become critically endangered over the decades, resulting in strict rules against wild-caught caviar and poaching. Likewise, it takes decades to raise sturgeon to sexual maturity prior to harvesting caviar, resulting in large investments and efforts. Nowadays, everyone can enjoy this flavorful treat for themselves-free from worry about cost or quality-thanks to modern production practices and a wide variety of sturgeon species that make caviar accessible on any budget.
