Imperial caviar or "golden osetra" comes from mature white sturgeon and is considered to be among the most exclusive types of caviar on the planet. It was once reserved special for Russian Czars and royalty. It is believed that the ancient Persians were the first to consume imperial caviar, as they would eat it for its nutritional benefits as well as for taste. To this day, imperial osetra caviar is a favorite among connoisseurs around the world, as its delectable taste and texture are of extreme value in a myriad of cultures.

What makes Russian imperial caviar such a delicacy is its "golden" quality. The color of imperial caviar varies between gold and green, lending itself as an attractive part of any dining presentation. Its flavor is nutty, earthy, and fruity, which is what makes it so coveted.
