Grade 1 vs Grade 2 Caviar: Trade Conventions Explained

Firm beads, consistent size, uniform colour: that is Grade 1 as seller PremiumCaviar describes it. Its Grade 2 allows slightly different sizes and colours, with a somewhat softer texture. The distinction sounds straightforward. Yet the current Russian standard for granular caviar uses neither label.

Grade 1 and Grade 2 are usually trade descriptions, not a universal official scale. To understand what they promise, start with the supplier's criteria, not the number on the tin.

What grade 1 vs grade 2 caviar usually means

Grade 1 generally signals a supplier's selection of firm, intact, relatively uniform beads. Grade 2 leaves room for more variation. In contemporary trade writing, these labels usually distinguish selections within a supplier's own range.

Caviar Star, a caviar seller, describes Grade 1 as meeting its preferred combination of sensory qualities. Its Grade 2 may fall short in several areas while remaining saleable caviar. Gourmet Food Store describes Grade 1 as large and firm, and Grade 2 as smaller. PremiumCaviar's descriptions likewise centre on size, colour and texture. None supplies measurements that every producer must meet.

Before comparing two tins, ask for the supplier's written criteria, especially when the labels come from different houses. Without a specification, a grade tells you nothing precise about permitted variation in diameter or firmness. The grading and quality hub sets out the wider framework.

The Russian GOST standard

Russia's current standard names three grades: Extra, Highest and First. There is no Second grade.

The applicable standard is GOST 7442-2017, Granular sturgeon caviar. Specifications, published in the official 2018 edition. Rosstandart lists it as in force, introduced in Russia on 1 February 2019 to replace GOST 7442-2002.

Section 4.2.2 names the three grades; Section 4.2.4 refers to the quality table. Extra also carries specific restrictions on raw material and additives. These categories cannot simply be relabelled Grade 1 and Grade 2.

Codex sets requirements for caviar, but it does not divide it into Grade 1 and Grade 2.

An interstate GOST and an EAEU technical regulation do different jobs. TR EAEU 040/2016, On the safety of fish and fish products, supplies mandatory safety requirements. Standards offer a voluntary route for demonstrating conformity. A standard being “in force” therefore does not require every tin to carry a GOST quality grade.

The foreword records adoption votes from all five EAEU members, among other countries. Adoption votes alone do not show how each country applies the standard at home.

Where First and Second appear historically

First and Second have a place in the historical standards, alongside a third grade: Highest.

The Soviet-origin GOST 7442-79, in the amended reprint cited, covered granular sturgeon caviar for domestic supply and export. It specified Highest, First and Second, rather than a simple two-tier system. Its categories help explain the vocabulary. Its export scope, however, does not establish how those grades were used in export trade or where modern English grading claims originated.

These short translations show what the historical standard allowed, rather than what the current standard requires.

First allowed medium or large eggs; Second also allowed small eggs. First permitted a slightly moist or thick consistency, with less easy separation. Second permitted more pronounced moisture or thickness and some membrane damage. The distinctions reached beyond appearance to how readily the eggs separated.

What Codex and other jurisdictions recognise

Codex sets requirements for caviar, but it does not divide it into Grade 1 and Grade 2.

Codex CXS 291-2010, Standard for sturgeon caviar, covers product identity and quality. The text records amendments in 2013, 2018 and 2024; the Codex register records a further modification in 2026. Its requirement for reasonably uniform eggs is a product specification, not a numbered grading ladder.

Codex is an international reference, not automatically binding national law. Nor is the historical First and Second hierarchy an official EU, UK or US retail grading scheme. A grade number should never be presented as government certification.

The US FDA's caviar guidance addresses the name of the food, not these grades. UK official guidance emphasises accurate, non-misleading food information. Great Britain applies the assimilated food information regulation, while Northern Ireland generally applies EU food information law. These rules govern naming and information, not grading.

What a grade cannot establish

A grade describes a quality tier. It does not identify the species, tell you where the roe was produced or authenticate the contents.

A supplier's sensory selection alone cannot establish that the caviar matches the claimed fish or origin. Keep those questions separate when reading a product description: ask for the named species, documented origin and supplier's traceability information. Then ask what the grade adds about appearance, texture or flavour. The prominent number should support the underlying description, not replace it.

Imperial, Royal and Reserve belong to a separate vocabulary too. They are not translations of the GOST grades. The guide to trade names explains those terms; bead size, colour and firmness examines the physical qualities themselves.

Does grade 2 belong in cooking?

Some sellers recommend it for cooking. PremiumCaviar explicitly suggests that use alongside its description of slightly softer texture and less uniform beads. That is a serving suggestion, not part of the historical grade definition.

Choose according to what the dish asks the eggs to do. If individual beads are the focus, consistent separation and texture may matter more. If caviar is incorporated into another preparation, visual uniformity may matter less. Neither use makes a supplier's grade an objective ranking of flavour.

For a tasting comparison, keep the producer and species constant where possible. Compare the stated selection criteria rather than assuming every Grade 1 outranks every Grade 2. For the broader assessment, read how caviar is graded.
