How to Buy Caviar: The Complete Guide

A 2023 Lower Danube study examined 149 caviar and meat samples using genetic and isotope analyses and uncovered illegal trade and misdescription. For the buyer, the lesson is immediate: look beyond the grand name on the tin. The findings are not a worldwide prevalence estimate.

Choose the fish and processing style first, then check the batch, seller and refrigerated journey home. A clear species name, traceable label and suitable storage instructions are the essentials. Together they help you make an informed choice; none alone establishes authenticity or safety.

How to buy caviar: start with the species

Beluga, Ossetra and Sevruga begin with different fish. Ask for the scientific name, not just the name on the front. Beluga means the species CITES lists as Huso huso; Ossetra or Oscietra commonly refers to Acipenser gueldenstaedtii or Acipenser persicus; Sevruga means Acipenser stellatus. Siberian sturgeon is Acipenser baerii. Kaluga is Huso dauricus, not beluga.

Imperial, Royal, Golden and Reserve identify neither species nor universal legal grades. Ask what the seller means by each, and how it grades individual batches. The guide to trade names separates these descriptions from the fish's identity.

For hybrids, establish both parents. A male Amur sturgeon, Acipenser schrenckii, crossed with a female Kaluga, Huso dauricus, has the CITES label code SCHxDAU: male first. Codex lists hybrids female first, so a written description of the parents may follow a different order from the label.

Choose for your palate with matching species to taste, rather than assuming one species suits everyone. Proposed genus changes appeared in 2025; this guide retains CITES names so you can match the fish to the tin's code. In October 2025 the Sturgeon Specialist Group rejected both 2025 revisions and proposed dissolving Huso.

What the word caviar tells you

Start with two questions: eggs from which fish, prepared how? The word caviar has different boundaries in food standards, customs and wildlife law.

Codex CXS 291-2010 covers salted roe, meaning fish eggs, from the sturgeon family Acipenseridae. It is an international reference standard, not automatically binding law. CITES and US wildlife rules cover Acipenseriformes, the wider order that also includes paddlefish.

EU and UK customs systems separate caviar from caviar substitutes under heading 1604, with EU subheadings 1604 31 00 and 1604 32 00 respectively.

If refrigerated caviar arrives warm, or its temperature history is uncertain, do not taste it to decide whether it is safe.

Those tariff categories do not settle retail naming. Misleading food information is prohibited by Regulation (EU) No 1169/2011 in the EU and Northern Ireland, and its assimilated, amended counterpart in Great Britain.

In the US, FDA guidance says unqualified caviar should mean salted sturgeon roe. Other roe should name the fish alongside caviar in the same type size; added artificial colour needs a prominent declaration. The guidance is nonbinding, but misleading labelling can breach food law. Check food naming and wildlife traceability separately.

Choose the processing style

Malossol means lightly salted. It tells you neither the species nor whether the product is safe. Compare the declared salt content: Codex specifies 3 to 5 g of salt per 100 g of finished caviar.

Ask whether the caviar is unpasteurised, pasteurised or previously frozen. Pasteurisation is a controlled heat treatment that can extend keeping time, change flavour and firm the egg membranes. Refrigeration instructions still apply.

Caviar from ovulated eggs is another distinct preparation. The eggs are collected from farmed fish after induced ovulation; Codex requires removal of the adhesive layer and hardening of the egg shell. It specifies the name caviar from ovulated eggs and requires any hormones used to be approved by the competent authority. Check the product description against the applicable country's naming rules.

What makes a batch worth choosing

Species sets the starting point. The quality of the batch depends on how the fish were raised, when the eggs were collected and what happened afterwards. Compare these details rather than treating the list as a ranking:

• Species and maturity: genetics influence the eggs, but the species name alone cannot describe a batch's quality. Ask about maturity at harvest: age alone does not establish whether eggs were collected at the right developmental stage.
• Water, feed and purging: ask how the farm monitors water conditions and avoids unwanted flavours. Establish what the producer means by pre-harvest holding in clean water and how it checks for off-flavours.
• Handling and salting: gentle separation, cleaning and packing help keep beads intact, with fewer broken eggs and less loose liquid. Compare the salt formulation as well as the species: salt influences both taste and preservation.
• Maturation and freshness: controlled holding after salting allows salt distribution and product development, so packed today does not automatically mean better. Judge remaining shelf life alongside processing history and temperature control, not the packing date alone.
• Traceability: an identifiable batch lets the seller connect the tin to production and handling records and investigate a problem.

Match the quantity and container to your plans

Choose your opening date before choosing your tin. Buy an amount you expect to finish at one sitting, or within the producer's stated period after opening. The unopened date does not cover leftovers.

For planning, this site's standard serving is 15 g, about half an ounce. A 30 g tin, about 1 oz, therefore provides two such portions. This is a serving convention, not a regulatory serving size or a limit on how much anyone should eat.

Food-grade tins and glass jars can both be suitable. Before buying, check that the closure is sound and the container carries its traceability label. Ask whether it is an original pack or repacked. Repacking is permitted under controlled conditions and does not, in itself, make the caviar inferior.

Six questions for any seller

Use the same checklist at a farm, deli or online seller. If you cannot inspect the actual batch label, request a photograph. Keep the answers with your order.

1. Which fish is it? Request the scientific name. For hybrids, ask for both parents, with male and female identified.
2. Where did the roe originate? Establish the country of origin and where the roe was harvested. Neither follows from the brand's headquarters or the repacking country.
3. When was it harvested and packed? Clarify which date the seller is giving, the date mark on your tin and its remaining refrigerated life.
4. Can I see the full CITES code? Check the species, source code describing origin category, country of origin, year, plant registration and batch identifier.
5. Is it original or repacked? A repacked label distinguishes origin from the repacking plant and country, and uses the repacking year.
6. How is it kept and delivered? Request the storage temperature, delivery arrangements, instructions after opening and procedure for delayed or warm deliveries.

Read the fields with the label guide and CITES code explanation, rather than guessing from letters. The original CITES label gives the harvest year; a repacked label gives the year of repackaging. Neither gives a complete freshness history.

Use the plant registration to check the legal facility against the public CITES register of caviar operations, rather than searching only for the brand. The register contains only processing and repackaging plants notified by Parties, not retailers, so an operation's absence alone does not establish that it is unlawful. The label supports traceability; it cannot authenticate the contents.

Know when to walk away

Pause when a seller cannot identify the species or origin, cannot explain refrigeration, or calls another species beluga. Kaluga Beluga is not a scientific identity. Ask which fish supplied the roe.

Treat wild as a claim to check, not a quality badge. Compare it with the named fishery's current restrictions. Be especially cautious about claims of legal wild Danube sturgeon products: the 2023 Lower Danube study introduced above concerned countries with sturgeon fishing bans. A convincing story needs evidence behind it.

Buying abroad and bringing it home

Being able to buy caviar in one country does not mean you may import it into another. Before travelling between the EU, UK, US, Switzerland, UAE, China, Japan, Russia or Australia, check both departure and destination authorities for wildlife documents, food restrictions, sanctions and biosecurity conditions.

According to Res. Conf. 12.7, Parties should consider limiting the personal-effects exemption to 125 g, about 4.4 oz, of labelled caviar per person. That exemption applies only where adopted nationally and does not override stricter rules. For US travel, beluga faces additional Endangered Species Act restrictions. A personal allowance does not automatically authorise it.

When the caviar arrives

Be there for delivery, or arrange for someone to receive it. Inspect the container, label and date immediately. Look for leakage, a damaged closure or swelling, and photograph any problems before contacting the seller.

If refrigerated caviar arrives warm, or its temperature history is uncertain, do not taste it to decide whether it is safe. A pleasant smell or intact seal cannot establish safety either.

Refrigerate an acceptable delivery immediately, following the producer's instructions. Codex specifies 2°C to 4°C for caviar at retail and 0°C to −4°C for wholesale storage and transport. For general home refrigeration, UK FSA guidance recommends 5°C (41°F) or below, while US FDA guidance recommends 4°C (40°F) or below. Follow any colder requirement stated for your caviar.

Keep the invoice and batch details until the caviar has been eaten. The guides to cold-chain delivery and home storage explain the next steps, with storage decisions tied to the product rather than a universal shelf life.
