When people talk about caviar, their thoughts usually drift to the Caspian Sea, Russian tsars, or Iranian fishermen. These are images that have defined the luxurious image of this delicacy for years. Yet today, one of the world’s most respected producers is not located on a distant coastline but in the Antwerp Kempen. In Turnhout, Royal Belgian Caviar has been writing a story for over three decades which is as exceptional as it is unexpected. What began as a daring experiment has grown into an international benchmark for quality embraced by the world’s greatest chefs.

​

During a visit to the company, it quickly becomes clear that this is not about mass production or marketing. Royal Belgian Caviar is all about knowledge, patience, and an uncompromising pursuit of perfection. Behind every can lies a production process that bears more resemblance to haute watchmaking than to traditional aquaculture. Everything is done with the same philosophy of total control, maximum quality, and respect for a centuries-old tradition.

​

From a Grain Mill to a Global Leader

​

Remarkably, the story does not begin with sturgeon, but with grain. Over generations, Joosen-Luyckx built a strong reputation in grain milling and the development of high-quality animal and fish feeds, including its own research and development department. It was precisely that expertise that would ultimately lay the foundation for an entirely new chapter.

 

In the early 1990s, several foreign sturgeon farmers approached the company with a persistent problem. Young sturgeon proved to be particularly vulnerable, and a large proportion of the fish did not survive their early stages of life. Thanks to years of experience in nutritional research, Joosen-Luyckx developed a specialized feed that more closely matched the sturgeon’s natural diet. The results were remarkable. For Flor Joosen, now CEO and the driving force behind Royal Belgian Caviar, a logical yet exceptionally ambitious question arose at that time. If Belgium had succeeded in developing the ideal feed for sturgeon, why couldn’t it also produce world-class caviar?

 

What seems obvious today was nothing short of revolutionary back then. After all, caviar came almost exclusively from the Caspian Sea. Belgium as a producer? Few believed it was possible.

​

10 Years of Investment Without a Single Gram of Caviar

​

While most food products reach the market within a few months, caviar requires an unprecedented investment of time. Over the course of about 10 years, Royal Belgian Caviar carefully built up its own breeding stock of various sturgeon species.

In order to make this possible, Flor Joosen traveled to Iran in the early 1990s—at the time still the cradle of traditional caviar production. There, in full compliance with the regulations in effect at the time, wild sturgeons were selected to form the foundation of the Belgian breeding stock. Those original fish laid the genetic foundation for what is today one of the most renowned sturgeon farms in the world. Over the next 10 years, that breeding stock was carefully expanded, and in 2002, the first Royal Belgian Caviar appeared on the market. Since then, all sturgeon have been raised entirely in-house, and the entire life cycle remains under Belgian control. That initial production amounted to barely about 150 kilograms.

 

Today, that has grown to several tonnes per year without ever losing sight of the company’s philosophy. “We don’t strive to be the largest producer, but rather the best,” says commercial manager Cédric Paquet. That statement perhaps best sums up the identity of Royal Belgian Caviar. Growth must never come at the expense of quality.

​

It All Starts with the Sturgeon

​

What sets Royal Belgian Caviar apart from many other producers is its exceptionally short supply chain. All sturgeon are bred in-house. The feed is also developed and produced entirely in-house. As a result, the company is completely aware of every stage a fish goes through during its life.

 

The first stage of life takes place in Turnhout. Once the young sturgeon are strong enough, they are moved to spacious ponds in Dottenijs, where they continue to grow in a peaceful, natural environment. Water quality is constantly monitored because, just as terroir defines a wine, water, feed, and living conditions also influence the final taste of caviar. For Siberian sturgeon, it takes about 10 years before they produce sufficient mature eggs. Beluga sturgeon require up to 18 years.

 

This means that every decision made today will influence the final product more than a decade later. It immediately explains why patience is perhaps the most important ingredient in Royal Belgian Caviar.

​

Science Serving Tradition

​

Although the production process utilizes state-of-the-art technology, the final preparation remains surprisingly true to centuries-old traditions. Before a sturgeon is selected, specialists use ultrasound to closely examine the quality of the roe. Only non-ovulated roe is eligible for production. This remains the international standard for high-quality caviar.

​

Then comes an extremely precise artisanal process. The eggs are carefully sifted, cleaned, and rinsed several times. Royal Belgian Caviar even developed its own rinsing technique for this purpose, which provides maximum protection for the delicate structure of the eggs.

​

Only Then Does the Caviar Master Take Over

 

Using the traditional malossol method, only a limited amount of salt is added. Not to mask the flavor, but to achieve the exact opposite: to allow the natural aromas to fully develop. Depending on the preferences of top international chefs, even the salt content can be subtly adjusted.

 

Notably, Royal Belgian Caviar never mixes roe from different fish. Each can comes from a single sturgeon, ensuring that the flavor, texture, and full traceability are preserved.

​

Why Fresh Packaging is so Important

 

Within the international caviar trade, a large portion of the production is repackaged. Large mother tins are opened, after which smaller portions are divided up for sale. According to Royal Belgian Caviar, this often results in a loss of quality. Contact with oxygen accelerates oxidation, causing the subtle aromas to change and the caviar to develop a metallic taste. That is why the company has resolutely opted for a different approach.

 

Each order is vacuum-sealed directly into the final tin in which the caviar then matures. This minimizes oxidation and guarantees exceptional freshness. It may seem like a small detail, but choices like these ultimately make the difference between good caviar and exceptional caviar.

​

Sustainability as a Matter of Course

 

Whereas wild sturgeon used to be fished in massive numbers in the Caspian Sea, fortunate enough, that practice is now a part of the past. Due to the sharp decline in natural populations, CITES banned the international trade in wild-caught sturgeon. Royal Belgian Caviar, however, had already made that shift much earlier.

 

Furthermore, the company goes to remarkable lengths in terms of environmental sustainability. Approximately 97 percent of the water used is purified and reused. The remaining portion is put to good use in agriculture. Moreover, this sustainable philosophy extends beyond caviar alone. The high-quality sturgeon meat is also processed into gourmet products that find their way to restaurants and specialty retailers.

 

Together, these elements create a virtually fully circular production process centered around respect for the animal.

​

A Belgian Producer Conquering the World​

 

What once began as a family project in the Kempen region has since grown into a staple of the international gastronomy scene. Belgian Michelin-starred chefs such as Tim Boury, Gert De Mangeleer, Nick Bril, Michael Vrijmoed, Willem Hiele, and Sang Hoon Degeimbre work with Royal Belgian Caviar because of its consistent quality and refined flavour.

​

Even far beyond our national borders, this Belgian producer enjoys an excellent reputation. Restaurants in Scandinavia, Germany, Japan, and the United States serve the caviar, while renowned chefs such as Tohru Nakamura and Koizumi Kouji deliberately choose the Belgian product.

 

This international recognition is no coincidence. It is the result of unprecedented control over the entire production process combined with the flexibility to develop specific flavour profiles in collaboration with chefs.

​

White Pearl, the rarest pearls in the house

 

Among the original sturgeon at the time were a few genetically unique albino specimens. Thanks to this exceptional combination, Royal Belgian Caviar now produces one of the most exclusive products in the international caviar world. White Pearl, the coloured albino caviar, is among the rarest caviars commercially available. Its subtle flavor, creamy texture, and exceptional rarity make it a delicacy that graces only the most exclusive tables.

 

It perfectly illustrates how science, nature, and luck sometimes come together.

​

More Than Just a Luxury Ingredient

 

Anyone who tastes a spoonful of Royal Belgian Caviar experiences much more than carefully salted sturgeon roe. Behind the refined salty notes lies a story of 30 years of investment, experimentation, and perfection. It is a story in which Belgian culinary expertise has grown into a global benchmark in gastronomy, where innovation goes hand in hand with centuries-old traditions.

 

Where sustainability isn’t just a marketing term but a fundamental principle. Perhaps that is ultimately Royal Belgian Caviar’s greatest achievement. The company has not only proven that top-quality caviar can be produced perfectly in Belgium but also that true luxury today revolves around authenticity, transparency, and craftsmanship. At a time when consumers increasingly want to know where their products come from, Royal Belgian Caviar is a prime example of how a short supply chain, full traceability, and uncompromising quality can grow into an international success story. The fact that the world’s greatest chefs no longer need to look to the Caspian Sea for this, but to Turnhout, says it all.

 

A Belgian product to be very proud of.
