Marino Rex Caviar S.r.l. is a company founded in the Republic of San Marino that brings Kaluga and Amur sturgeon caviar to market, processed with minimal salt according to the malossol method and shipped worldwide in vacuum-sealed packaging. Behind the product lies the meeting of centuries-old Russian expertise in fish farming with the technological possibilities opened up by aquaculture in the Far East.
The starting point is water.
The sturgeon grow in large tanks fed by spring water, automatically exchanged and therefore well oxygenated, with low stocking density: fewer fish in the same space means less stress and, according to the company, a higher-quality final product.
No additives or GMOs are used in raising the sturgeon, and no flavor enhancers or chemical preservatives enter the processing to preserve the taste.
In the jar, they state, there are only two things: caviar and salt.
It is precisely this starting condition that makes possible the choice defining the product: a very low percentage of salt. Malossol in Russian means precisely “little salt,” and denotes a caviar in which salting serves to preserve, not to mask.
The stated result is a balanced, lingering and delicate flavor, with a final hazelnut note. The eggs have a diameter of between 3.3 and 3.8 millimeters, a color ranging from black to ochre-brown, and a texture that stays separated, without becoming mushy, if the product is stored properly.
Overseeing the entire chain, from farming to salting through to selection and storage, are technicians and specialists from Astrakhan, the city on the Volga delta historically linked to caviar processing, with decades of experience in the sector.
This is the most delicate stage: the amount of salt, the contact time and the temperature determine the difference between fine caviar and an ordinary one.
From warehouse to table at a controlled temperature
The vacuum-sealed packaging comes from the historic French manufacturer Desjardin, one of the leading names for containers in the industry.
Shipments depart from a warehouse registered within the European Union, with DHL and UPS couriers and tracking throughout the journey, in thermal boxes with cooling elements chosen according to distance. The stated storage temperature is between -2 and -4°C and must be maintained at home as well: once opened, the caviar should be consumed within five days, always taken with a clean, dry teaspoon.
The company also states that it operates under official authorization for food processing, in compliance with European health and safety standards.
Alongside sales to private customers there is a professional channel: restaurants, hotels and distributors, with formats available on request, a consistent taste profile from batch to batch, and documentation available for audits. Orders, whether private or professional, are placed through the website marinorex.com, where quantities and delivery terms can be specified.
