Discover who we are

Riofrío is the favourite caviar of gourmets all over the world, the most exclusive delicatessen shops and numerous Michelin-starred chefs.

Our sturgeons, which include the variety Acipenser naccarii, Acipenser gueldenstaedtii (Osetra) and Huso huso (Beluga), are farmed in the best waters in Spain and probably the world, at a constant temperature between 14 and 15ºC, which practically replicates their wild habitat in a natural way.

Due to its freshness and nuanced flavour, Riofrío Caviar is recognised as one of the world's best.



Originally used for milling, fulling cloth and powering trip hammers, the waterfall at the source of the river Frío was discovered in the 1960s by Doctor Domezain, the pioneer of fish farming in Spain. A doctor from the region of Navarre, he founded the Riofrío brand in 1963 together with two partners. Domezain was attracted to this area for its unique conditions: the water flows all year round from a natural spring located 300 metres from the pools, at a stable temperature of between 14-15º C.

Visitas Caviar de Riofrio


Domezain started to fill the farms with trout, becoming renowned for its famous Ríofrio trout brand. The flavour of the fish, the restaurants on the riverbank, the beauty of the environment and the strategic location began to attract thousands of visitors to this small corner of the Loja mountains.



In the 1980s, the Domezain family began to breed sturgeon in captivity to produce caviar. This re-introduction of sturgeon to Riofrío, very close to the Guadalquivir waters where they had lived in the wild, immediately aroused a lot of scientific interest.
In the 1990s, a great opportunity presented itself: an international decree granted sturgeon with endangered species status, and therefore banned it from being fished.
Today, all caviar comes from non-wild fish, therefore its quality and excellence depends solely on the place where it is farmed. Due to the quality of its water, its natural temperatures and hours of sun in the area to the west of Granada, Riofrío Caviar is of a quality that is unique in the world.


Organic caviar

When the CITES decree became law, prohibiting the fishing of sturgeon, very few fish farms, hardly any at all, had female sturgeon ready to produce caviar. Riofrío was one of them, thanks to the vision of the Domezains, who had started to work towards this goal years before.
It was also the first fish farm to obtain organic certification, and in the year 2000, Riofrío Caviar became the world's first organic caviar, achieving the first certification for caviar and the breeding of sturgeon.
Four biologists currently work at Riofrío and they carefully rear more than one hundred thousand sturgeon. The challenge, which is met year after year, is to create a product of sublime quality that shows the ultimate respect for the environment and the animals' quality of life. To do so, we work using a system free from the use of antibiotics and forced growth feeding, as well as dedicating a third of the surface of the fish farm to maintaining the purity of the water, which is returned clean to the river and is key to the quality of the caviar. This completely natural purification system has a significant effect on the development and health of the characteristic bird life of Riofrío.
Thanks to a pioneering system that is 100% organic and sustainable throughout the whole supply chain, Caviar Riofrío continues to be a global benchmark.

What does organic mean?

The Organic Aquaculture regulations in Europe and benefits for the consumer

All Organic production in the European Union is regulated by Regulation 834/2007. This Regulation has subsequently been extended by Regulations 889/2008; 710/2009 and its successive modifications.
Briefly summarised, we could say that Organic Aquaculture meets all these regulations, which are demanding and complex and regulate the whole process; production environment, breeding process, feeding, management, animal welfare, elaboration process and the influence of all this on the environment without forgetting the strictest health guarantees and quality product for the consumer.

In turn, the fulfilment of all these conditions is monitored by an independent external body, authorised by the EU. They have the right at any time to enter into any part of the company and carry out checks on any situation, taking samples to analyse raw materials as well as products, as well as the water before and after production and anything else they like, including complete traceability and accounting. All the suppliers of the company have to fulfil the same conditions and undergo the same procedures.

This comprehensive control system is an important guarantee for the demanding consumer, when consuming a product from Organic Aquaculture they know they are enjoying a good and healthy product, free from growth accelerators, chemical residues, pesticides, GMO’s and any other products dangerous to their health, as well as knowing that the production respects the environment and animal welfare.
