Caviar — the tiny, glistening black pearls on the finest of gourmet plates — is synonymous with luxury. But have you ever wondered why caviar is so expensive? Why do these little fish eggs command thousands of dollars for just a few ounces? The answer lies in the delicate process of caviar farming and the rarity of the sturgeon fish that produce it.
In this article, we’ll break down what makes caviar so valuable, how it’s farmed, and what caviar farming involves. We’ll keep the language simple, the facts fascinating, and the insights crystal clear!

What is Caviar?
First things first, what exactly is caviar?
- Definition: Caviar refers to the salted fish eggs (roe) harvested from sturgeon species.
- Types of Caviar: The most prized caviar comes from different sturgeon varieties such as Beluga, Osetra, and Sevruga.
- Colour and Texture: Caviar ranges from glossy black to shimmering golden. Its texture is soft yet firm, with a burst of flavour when eaten.
- Taste: True caviar has a subtle, buttery, and slightly salty taste.

Why is Caviar So Expensive?
Caviar is one of the most expensive foods in the world, and here’s why:
1. Sturgeon are Rare and Ancient
- Sturgeons have existed for over 200 million years.
- Due to overfishing and habitat loss, wild sturgeons are now critically endangered.
- Farming sturgeon is essential to produce caviar sustainably.
2. Lengthy Growth Time
- Sturgeons take 10 to 20 years to mature and produce roe.
- This long growth period means farmers must invest years before they can harvest caviar.
3. Delicate Harvesting Process
- Each fish is handled with extreme care to extract the roe without damaging it.
- Harvesting involves precise techniques to ensure the eggs remain intact and high quality.
4. Labor-Intensive Process
- From farm maintenance to caviar extraction, the process involves highly skilled workers.
- It takes patience, skill, and attention to detail, to drive up labour costs.
5. Strict Regulations
- Due to the endangered status of wild sturgeon, strict laws govern caviar production.
- Legal, high-quality caviar comes only from licensed farms, adding to its exclusivity.
6. Quality Control
- Caviar must be perfectly processed and preserved.
- Even slight imperfections in taste, texture, or handling can downgrade its value significantly.
How is Caviar Farmed?
With wild sturgeon populations dwindling, caviar farming has become the primary method of producing this luxury delicacy. Here’s a step-by-step look at the process:
1. Raising the Sturgeon
- Sturgeons are raised in large freshwater ponds or tanks.
- Farms carefully control water quality, temperature, and feeding schedules to ensure healthy fish.
2. Determining Maturity
- Female sturgeons are monitored using ultrasound technology to determine when their roe is ready for harvesting.
- This process can take anywhere from 8 to 20 years, depending on the species.
3. Harvesting the Roe
- Once the roe reaches maturity, the fish is either harvested traditionally or using a “no-kill” method.
- In the no-kill method, the roe is extracted without killing the fish, allowing it to produce more caviar in the future.
4. Processing the Roe
- The roe is carefully cleaned, salted, and graded.
- The salting process (known as “malossol,” which means “lightly salted”) preserves the caviar while maintaining its delicate flavour.
5. Packaging and Storing
- Caviar is packed into airtight tins or jars to maintain freshness.
- It is stored in cold temperatures to ensure quality and taste.

Types of Sturgeon and Caviar
Different sturgeon species produce different types of caviar. Here are the most popular ones:
- Beluga Caviar:
- Colour: Pale to dark grey
- Taste: Creamy and rich
- Price: The most expensive, due to its rarity
- Osetra Caviar:
- Colour: Brown to golden
- Taste: Nutty and complex
- Popularity: Valued for its versatility and flavour
- Sevruga Caviar:
- Colour: Dark grey to black
- Taste: Bold and briny
- Affordability: More accessible compared to Beluga
- Kaluga Caviar:
- Colour: Dark grey with a glossy sheen
- Taste: Smooth, similar to Beluga
Sustainable Caviar Farming
Due to the decline of wild sturgeon populations, sustainable farming practices are critical. Here’s how modern farms maintain sustainability:
- Breeding Programs: Farms focus on responsible breeding to prevent overpopulation.
- No-Kill Harvesting: Some farms use techniques that allow the fish to survive after roe extraction.
- Water Quality Control: Ensuring clean, healthy water reduces environmental impact.
Caviar’s high price tag isn’t just about luxury — it reflects the rarity, effort, and care involved in its production. From the ancient sturgeon species to the meticulous farming and harvesting process, every step contributes to this delicacy’s exclusivity. Next time you see a small tin of caviar costing hundreds or even thousands of dollars, you’ll know exactly why!
