Siberian sturgeon caviar is a prized delicacy obtained from the roe (eggs) of the acipenser baerii species of sturgeon fish. Also known as oscietra caviar, it originates from sturgeon found in the Caspian and Black Seas.

Siberian sturgeon caviar has a rich history and is distinguished by its deep black color, glossy appearance, and delicate taste. The eggs are small to medium sized, ranging from 2.4 to 2.8 mm. It is considered one of the premium caviar types due to its exquisite flavor and texture.

History of Siberian Sturgeon Caviar

The harvesting of sturgeon for their caviar dates back centuries in Russia. Siberian sturgeon caviar was a food reserved for Russian tsars and nobility in the 18th and 19th centuries. It gained popularity in North America and Europe in the early 20th century as a luxury food item.

Global production of Siberian sturgeon caviar was 1,200 tons in 2020 according to the Food and Agriculture Organization of the United Nations (FAO). China leads production with over 60% share, while Russia produces around 20% of the global supply. The average price per kilogram was $2,500 in 2022 based on data from the International Trade Centre (ITC).

How is Siberian Sturgeon Caviar Harvested?

Traditionally, Siberian sturgeon were fished from the wild in the Caspian and Black Seas. Their caviar was extracted and processed by hand. But due to overfishing and reduced sturgeon populations, aquaculture now plays a major role in caviar production.

On fish farms, female sturgeons are raised until maturity (typically 7-10 years) before their eggs are harvested. The process is very meticulous, done surgically to extract the roe without harming the fish. The eggs are sieved multiple times to remove impurities and then packed based on size and quality.

What Makes Siberian Sturgeon Caviar Unique?

Deep black pearls with a slight golden hue
Small to medium sized eggs (2.4 – 2.8mm)
Firm texture that pops gently in the mouth
Refined, buttery, and nutty flavor
Lingering mild brininess

The unique characteristics of Siberian sturgeon caviar are influenced by the sturgeon’s diet, water environment, genetics, and processing techniques. Siberian sturgeon are carnivorous bottom feeders that dine on small fish, crustaceans, and mollusks – imparting a complex and savory flavor to their roe.

Sustainability Concerns with Siberian Sturgeon Caviar

Environmental issues plague the caviar industry:

Wild sturgeon populations are endangered from overfishing and habitat destruction – listed as “vulnerable” by the IUCN Red List of Threatened Species
Illegal and unregulated fishing occurs in the Caspian Sea
Sturgeon can live up to 100 years but take 10+ years to reach maturity

Aquaculture provides an alternative for producing caviar sustainably. But care must be taken to maintain genetic diversity in sturgeon breeding pools. Reputable caviar sellers follow best practices for responsible and humane harvesting.

How to Buy Quality Siberian Sturgeon Caviar

Harvest date – fresher is better
Cold chain tracking – proper refrigeration
Species and origin certification
Visually appealing eggs – firm, shiny, no blemishes
Serving the caviar chilled but not frozen

2. Where to Buy Authentic Siberian Sturgeon Caviar

Specialty food stores like Dean & DeLuca
High-end grocery stores and fish markets
Direct from reputable purveyors online
On occasion from Costco or Sam’s Club

Check for proper import labeling. Beware of counterfeit caviar and always buy from trusted sellers. The United States imported over 30% of the global supply of Siberian sturgeon caviar in 2020.

Storing and Handling Tips for Siberian Sturgeon Caviar

Keep chilled at 28°F to 32°F (-2°C to 0°C)
Do not freeze – freezing ruins the delicate texture
Store in original tin or glass jar
Keep away from odorous foods
Consume within 2-3 weeks of opening

Avoid introducing moisture, oxygen, light, or heat as these will degrade caviar quickly. Never use metal utensils which may oxidize the roe – use mother of pearl, horn, or wood. Handle the eggs gingerly to avoid damaging them.
