Sturgeon Caviar: Everything You Need to Know

Are you interested in delivering the extraordinary and flavorful world of caviar directly to your taste buds? Perhaps you intend to elevate party hors d'oeuvres and impress your guests with its tangy flavor and magic mouthfeel. Or, maybe you have seen caviar served in elegant films or heard that eating caviar can be an interesting experience and are curious to try this centuries-old delicacy.

Whatever your reason, caviar is a gift from the sea that should be tried and treasured by everyone, not just royalty! The first thing to learn when starting to develop a palate for caviar is that you should always obtain true sturgeon caviar. Only species of fish in the sturgeon family produce true caviar. 


Sturgeon is the common name for the 27 species of fish belonging to the family Acipenseridae. All of the species of this fish are native to the temperate waters of the Northern Hemisphere.

While sturgeon are found mainly in the Caspian Sea, they are also found in the Black Sea, parts of the Pacific Northwest, the South Atlantic regions of North America, and in big European lakes and rivers. Although sturgeon is a saltwater fish, they lay eggs in freshwater, which is a piece of modern sustainable farming efforts. 


Caviar identifies the matured eggs of the fish sturgeon. As all caviar lovers know, only sturgeon eggs qualify as caviar! Of course, when researching the right product(s), you may come across the word “roe.” Roe is a more general word that means fish eggs, but roe and caviar are definitely not interchangeable. 

Roe refers to any and all fish eggs, including those from salmon, trout, flying fish, and others. Sturgeon fish eggs are uniquely identified as caviar. “Red caviar” is not caviar - it is salmon egg and should more correctly be called salmon roe. 


You might be surprised to learn that sturgeon caviar has not always been a luxury food. It is rumored that before Ivan the Terrible fell in love with caviar, Russian fishermen (as early as the 12th century) would serve it with porridge or eat it by the bowl. United States fish roe has also not always been an expensive delicacy.

The American caviar industry began in the late 1800s when, along the Delaware River or the Columbia River, sturgeon eggs were harvested quickly and abundantly. By the turn of the 20th Century, caviar had become so commonplace in the New York area that it was colloquially named Albany-beef. At that time, the United States could produce enough of its own jars of caviar to sustain demand.

Today, most of the world’s caviar comes from sturgeon fish farms in fifty or more nations, including the United States, France, Italy, and Iran. China is poised to be the world’s largest producer. Contributing to caviar’s status as a luxury food over the years has been the increase in consumption combined with the scarcity of wild sturgeon caviar due to habitat destruction and life cycle limitations.

Various restrictions on importation from the United States Fish and Wildlife Service have been implemented in an attempt to protect these magnificent fish.

Habitat and lifecycle restrictions are not as important in other fish species. These circumstances lead to an increase in the number of “caviar” alternatives -- imposters really --  an even greater need to distinguish between the high-quality treat that is true caviar and fake caviar. We at Imperia Caviar are committed to producing true sturgeon caviar as an accessible luxury for everyone to enjoy without causing harm to the environment. Our caviar is produced through sustainable, eco-friendly, nearly wild farm environments.  


Caviar is usually divided into two grades, determined by professionals trained in grading quality, to alert consumers of certain aspects of the caviar. The grade is determined by factors including egg color, size, clarity, taste, aroma, and firmness.

Usually, Grade 1 caviar includes the firmest, largest, most intact eggs with fine color and flavor. Grade 2 caviar, while also tasty and decadent, consists of less delicate and less uniform eggs. Imperia Caviar believes in providing the most beautifully cured caviar and sells only the best, A+ Grade 1 caviar. 


There are many sturgeon caviar varieties. Each type has an interesting taste, color, and texture variances. For example, there is Siberian caviar, Paddlefish caviar, bony fish Bowfin caviars,  Hackleback caviar from the Shovelnose sturgeon, White sturgeon caviar, and others.

That said, not all caviars are made equal; there are only a few types of the best sturgeon caviar that are legally sold in the USA today, including Osetra caviar, Sevruga caviar, and Kaluga Caviar. They vary in, among other things, size, color, and flavor. 

Many types of caviar are found worldwide in the Black Sea or the Caspian Sea, bordered by countries like Iran and Russia. However, caviar connoisseurs know some of the best caviar comes from the United States.

Hackleback caviar, for example, is indigenous to the Missouri and Mississippi rivers, with a beautiful black color, and sturgeon are found in the lakes of Wisconsin as well.

These differences, as well as cost and availability, play a large role in determining value and prestige. Another is the Almas Beluga caviar, which arises from a rare form of Iranian Beluga. This Persian albino sturgeon is usually between 60-100 years old and is the most expensive and exclusive type of caviar. In fact, Almas holds the Guinness World Record for the most expensive caviar at a cost of $34,500 per kilogram!

Beluga Sturgeon

Originating from the Caspian Sea, Beluga is often considered to be the most luxurious caviar in the world and is generally the most expensive of all accessible caviar varieties. Reaching lengths of up to 24 feet (7 meters) and weighing up to 3,000 pounds (1500 kilos), Beluga are massive.

While Beluga sturgeon may live to be over 100 years old and produce several hundreds of pounds of eggs, they are also critically endangered. This rarity in availability, combined with being one of the most reputationally desirable caviars in the world, contributes to the exorbitant cost range of $5,000 to $10,000 per kilogram.

With large, pearlescent eggs of light glistening gray, Beluga has a smooth, butter-like texture and rich, subtle flavor that melts in your mouth. It is, however, illegal to import Beluga caviar to the United States.

Osetra Sturgeon

Osetra (also called Osciètre) Sturgeon caviar is a flavorful winning analog to Beluga.  The Royal Osetra is equally considered one of the best caviars in the world. Osetra eggs are smaller than Beluga caviar and come in fine, medium-sized grains consistent in size.

Ranging in color from golden to brown, Osetra caviar has a nutty, rich flavor. The lighter the eggs, the older the sturgeon. Thus a lighter, fine grain is of a richer flavor.

Sevruga Sturgeon

Also known as starry sturgeon, Sevruga are native to the Caspian and Black Seas. They can also be found in the Aegean and Azov Seas. Due to quicker reproduction rates compared to Beluga and Osetra, Sevruga has higher availability.

Sevruga’s small and delicate gray to black eggs has a crunchy texture that pops with intense flavor. They are also the smallest-egg-producing Sturgeon, and their flavor profile begins with a distinct marine flavor, complemented by notes of nut and cream.  

Kaluga Sturgeon

Known colloquially as the “river beluga,” Kaluga is a farm-raised type of sturgeon caviar. This approach allows for greater sustainability of the species and stricter controls for uniformity and quality.

The taste of Kaluga is similar to Beluga, offering a creamy, smooth, and nearly buttery texture. In addition to sharing the Beluga’s exquisite taste and texture characteristics, Kaluga caviar can be eaten guilt-free, knowing that the delicacy you are consuming is eco-friendly and sustainable.  


Some people shy away from trying caviar because of the cost. Perhaps you want to try black caviar, but your local supermarket does not sell or offer a good, fresh selection. Alternatively, you may be put off by caviar’s fancy reputation or could think the price tag is well outside any affordable range. 

While it is true that the expense and availability of caviar are driven by supply and demand relationships, there are other factors.

Imperia Caviar is at the forefront of the culinary movement to make delicious delicacies affordable. Our mission is to make delicious, sustainable, and ethical caviar accessible to many at a fraction of the usual retail cost. We also offer uncompromising service.
