Albino Sterlet, Albino Beluga and Almas Caviar: The Truth About White Caviar

Danube Caviar describes its albino sterlet roe as butter-like in colour when freshly prepared, turning golden with maturation. That transformation captures the fascination of white caviar: pale sturgeon eggs whose appearance invites questions about the fish behind them.

The answers begin with species, not shade. Albino sterlet is a documented source; golden Ossetra occurs without an albino claim; and supplier records also describe albino beluga. “Almas” is a trade name applied to more than one species. Neither that name nor the colour alone identifies the fish or establishes albinism.

Albino sterlet: quick reference

• Common and trade names: sterlet; albino sterlet; white or golden caviar (sources 2 and 3).
• Scientific name: Acipenser ruthenus. Albinism is a trait, not a species (source 2).
• CITES listing and code: Appendix II; RUT (source 1).
• IUCN status: Endangered, according to the IUCN assessment published in 2022.
• Native range: rivers draining into the Black and Caspian seas, and Siberia.
• Egg diameter: 2.0 to 2.8 mm in UF/IFAS guidance for sterlet eggs assessed for artificial spawning, rather than finished albino caviar.
• Pale roe colour: Danube Caviar describes it as butter-like when freshly prepared, becoming golden with maturation (source 3).
• Documented farming: a 2019 study describes albino sterlet bred at Wasosze Fish Farm in Poland.
• Wild trade: CITES-regulated. Pale colour creates no exemption from species-specific wildlife trade requirements (source 1).

What makes white caviar pale?

Albinism is an inherited disruption of melanin production. Melanin is a dark pigment in fish tissues; oculocutaneous albinism affects pigmentation in both the body and eyes. Danube Caviar describes its albino sterlet roe as pale when fresh and golden after maturation. Colour alone, however, cannot reveal the underlying pigmentation mechanism.

Leucism is different. It describes reduced or absent body pigmentation while eye pigmentation remains, and concerns the distribution or development of pigment cells. The terms are not interchangeable. Neither a pale fish nor pale eggs distinguish the two mechanisms, and leucistic skin does not establish that the ovaries produce unpigmented eggs.

The research on albino sterlet reaches beyond outward appearance. A 2019 microscopy study examined ovaries from cultured albino females in two experimental breeding groups, providing direct evidence of their reproductive biology. Its scope was the fish under study, rather than the caviar market or the origins of every pale egg.

One more distinction matters: “white sturgeon” is the common name of Acipenser transmontanus. It does not promise white eggs. “White caviar” describes appearance; albino sterlet describes a pigmentation trait in Acipenser ruthenus. These are three different terms, not alternative names for the same thing.

Which fish produces pale roe?

Albino sterlet, pale Ossetra and products described as albino beluga all belong in the picture. The evidence ranges from published research to supplier descriptions; authenticating a particular container still requires its own records.

Albino sterlet

Danube Caviar’s supplier listing at the EU-Japan Centre identifies its Almas as albino sterlet caviar, while the published ovarian research documents the fish’s reproductive biology. For its wider biology, see sterlet caviar.

Pale Ossetra

Golden colour also occurs in Ossetra without an albino identification. FAO’s account of the caviar trade records golden and grey-gold Ossetra alongside dark-grey roe, associating Ossetra principally with Acipenser gueldenstaedtii and Acipenser persicus. Golden Ossetra therefore belongs in any account of pale caviar, but “golden” should not automatically become “albino”.

Albino beluga

Ivory, pearl-white and pale-gold eggs feature in La Perle du Caviar’s description of its Almas, identified by the supplier as albino Huso huso from Iran. The species, origin and colours are the supplier’s claims.

For legal identification, CITES uses Huso huso for beluga, although WoRMS now accepts Acipenser huso. This page follows the name retained by CITES. See beluga caviar for the species behind the marketing name.

Is most white caviar albino sterlet?

There is no reliable worldwide species breakdown for white caviar. The available trade records cannot answer that question: CITES records species and other trade characteristics, but its standard fields do not identify roe colour or albinism. A count of sterlet exports therefore cannot reveal how much of that roe was white.

Without that foundation, “one in a million” is a phrase, not a usable production statistic.

The database also records reported international movements, rather than providing a complete census of production or domestic sales. Documented albino sterlet products establish availability. They do not establish that sterlet supplies most legal white caviar.

Rarity needs a denominator. A useful claim specifies both a population and a period, whether it counts fish screened, albino individuals identified or kilograms of pale roe produced. Without that foundation, “one in a million” is a phrase, not a usable production statistic.

What Almas means, and what it does not

Almās means diamond in Persian. Historical dictionaries record the word independently of its modern use as a caviar trade name.

It is an evocative name, but it cannot identify a species. The sterlet and beluga examples above make that clear. Read Almas alongside the scientific name and traceability information, just as with other caviar trade names.

The stories need equal care. Rossini Caviar repeats an account that Almas was reserved exclusively for the tsar. That is a modern supplier’s account, rather than contemporary evidence of an exclusive court entitlement. Tales involving shahs or tsars belong to unverified tradition unless documented history supports them.

How to read the label on white or golden caviar

Start with the species code. Colour is a description; the code identifies the declared fish. Under Resolution Conf. 12.7 (Rev. CoP17), Annex 1 sets out the universal labelling guidelines and Annex 2 lists species codes: RUT means sterlet, HUS beluga and GUE Russian sturgeon.

This is a teaching example, not a real label: XXX/?/ZZ/0000/0000/000. Every value is deliberately unusable. The string shows only the order of fields.

1. Species: XXX marks the species-code position. A real code identifies the declared species, not an albino variety.
2. Source: ? marks the source code position, indicating how the specimen was obtained. C denotes specimens meeting CITES captive breeding criteria; W denotes wild origin. Neither means white, golden or superior.
3. Origin and year: ZZ and 0000 represent the origin country and harvest year on an original processing label.
4. Plant and lot: the final two fields connect the container to processing and batch records. For repacked caviar, the year is the repacking year; repacker details remain separate from the origin country.

A CITES label provides a traceability declaration. Laboratory identification and evidence of albinism are separate matters. For a white-caviar claim, ask for lot-linked evidence that names the fish and explains how its albino identification was made.

Consumer descriptions and wildlife trade labels also answer different questions. Rules vary worldwide, including in Switzerland, the UAE, China, Japan, Russia and Australia; some jurisdictions allow conditional 125 g exemptions. In the EU, Regulation (EC) No 865/2006 implements wildlife trade provisions. Great Britain has its own amended legislation, while applicable EU rules extend to Northern Ireland.

In the United States, 50 CFR 23.71 addresses international trade in sturgeon caviar. The retail-description guidance below does not establish permission to import beluga.

The FDA guidance also calls for an ingredient list. For the complete decoding method, use how to read a caviar label.

Does pale colour predict quality or flavour?

Golden tells you how caviar looks. It does not tell you how salt, aroma and texture will balance in the mouth. FAO’s historical grading account considers grain integrity, firmness, size, colour and flavour together, rather than supplying a colour-to-flavour formula.

A 2014 sensory study associated consumer acceptance of the caviars tested with several attributes: firmness, sea freshness, fresh butter flavour and black colour. Those are findings about the tested caviars, not a preference shared by every consumer or a flavour profile for albino roe.

The study compared caviars from sturgeon fed different diets. It does not establish that albinism itself makes roe milder or more delicate. Equally, a producer’s tasting notes belong to the named product: a description of one pale caviar should not become a promise about them all.

Ask four questions: which fish supplied the eggs, what supports the pigmentation claim, how was the batch processed, and do you enjoy its texture and flavour? Let the records explain the fish and the tasting answer the last question. Black versus golden caviar explores the comparison further.
