Beluga, Oscietra, and Baeri are the three most important caviars in a modern specialist catalogue. They come from three different sturgeon species, produce three distinctly different eggs, and sit at three different price points. This guide compares them head to head on pearl size, colour, flavour, finish, price, and the right occasion for each, so you can choose with confidence.
Quick Comparison
- Beluga (Huso huso): largest pearls, softest texture, long buttery finish. The most prized and most expensive caviar in the world.
- Oscietra (Acipenser gueldenstaedtii): medium-large golden pearls, nutty and buttery with a clean finish. The connoisseur's favourite and our flagship.
- Baeri (Acipenser baerii): medium pearls, nutty and lightly smoky, shorter but clean finish. The approachable premium at an accessible price.
Beluga Caviar
Beluga caviar comes from the Huso huso sturgeon, the largest member of the sturgeon family. A mature Beluga can weigh more than a tonne and reach three metres in length. Because of its size, a Beluga sturgeon takes 15 to 20 years to reach sexual maturity, and its eggs reflect that slow growth.
Pearl Size and Texture
Beluga pearls are the largest of any caviar, typically 3.0 to 3.5mm in diameter. The membrane of each egg is thin and delicate, which gives Beluga its famously soft pop. When the egg releases on the palate, the sensation is closer to butter dissolving than to the firm click of smaller caviars.
Colour
Beluga colours range from light steel grey to almost black. Paler pearls from older fish are rarer and more prized. A pale tin is a sign of provenance.
Flavour
The flavour is the longest and creamiest of any caviar. Beluga opens with a smooth butter note, develops a gentle nuttiness, and finishes clean with no sharpness. There is no fishiness in good Beluga. Everything about the flavour is long, slow, and elegant.
Price
Beluga is the most expensive caviar because Beluga sturgeon are slow-growing, relatively rare, and strictly regulated under CITES. Expect to pay several hundred pounds for 30g to 50g of premium Beluga. For a special occasion it is the benchmark. For everyday tasting it is not the right choice economically.
When to Choose Beluga
Milestone events. Engagements, major birthdays, anniversaries, corporate gifts at the highest end. Beluga is served in small quantities because the experience does not scale with volume. 30g to 50g per person for a celebratory course is generous.
Oscietra Caviar
Oscietra caviar comes from the Acipenser gueldenstaedtii sturgeon, known as the Russian sturgeon. The fish matures in 10 to 12 years, roughly half the time of a Beluga, and produces a very different pearl.
Pearl Size and Texture
Oscietra pearls sit between Beluga and Baeri at roughly 2.5 to 3.0mm. The membrane is firmer than Beluga but softer than Baeri. The pop is distinct and satisfying. You feel the egg release without the fragility of Beluga or the firmer resistance of smaller caviars.
Colour
Oscietra is defined by its golden-to-amber sheen. The best Oscietra pearls glow a rich bronze. Some tins show a hint of olive-green or deep gold. This golden character is what makes Oscietra instantly recognisable.
Flavour
Oscietra has the most distinctive flavour of the three. It opens with a pronounced nutty note, often described as hazelnut or toasted almond, and builds into a buttery creaminess through the finish. The finish is clean and long. Many chefs prefer Oscietra over Beluga because the flavour is more assertive and more memorable.
Price
Oscietra sits below Beluga and above Baeri. Expect to pay roughly 60 to 70 per cent of Beluga prices for equivalent tin sizes. The price-to-pleasure ratio is excellent, which is why Oscietra is often called the connoisseur's favourite.
When to Choose Oscietra
Oscietra is the right caviar for any occasion where you want a premium experience without the Beluga price tag. Intimate dinners for four to eight. Restaurant service. Gift hampers for serious food lovers. Our Royal Oscietra is hand-selected for larger, firmer pearls and more pronounced golden colour.
Baeri Caviar
Baeri caviar comes from the Acipenser baerii sturgeon, native to Siberian rivers. The fish matures in 7 to 8 years, the fastest of the three, which is why Baeri is the most economical premium caviar.
Pearl Size and Texture
Baeri pearls are medium sized, around 2.2 to 2.7mm. The membrane is firm and gives a clean sharp pop. The eggs are uniform in shape and hold their integrity well under service conditions, which makes Baeri popular in restaurants.
Colour
Baeri ranges from dark anthracite grey to jet black. The colour is deeper and more consistent than either Beluga or Oscietra. Some Baeri has a faint olive undertone.
Flavour
Baeri flavour is nutty with a touch of smokiness. It is lighter than Oscietra but more pronounced than salted freshwater fish roe. The finish is clean and relatively short, which makes Baeri an excellent caviar for canapes and pairings where the other flavours on the plate deserve space.
Price
Baeri is the most accessible premium caviar. Expect to pay around 35 to 45 per cent of Beluga prices for equivalent tin sizes. This makes Baeri a practical choice for dinner parties, restaurant starters, and tasting flights.
When to Choose Baeri
First-time caviar buyers. Dinner parties where you want caviar for six to twelve guests. Tasting sets where you compare sturgeon species. Blini and creme fraiche canapes where the caviar is one flavour among several.

Which Should You Choose?
Your choice depends on the occasion, the guest count, and the budget. Three decisions make it clear.
If You Are Buying for a Single Special Event
Buy Beluga if the event warrants it. A 30g tin shared between two or four people as a celebratory course is the most impactful way to spend on caviar. The soft texture and long finish will be remembered.
If You Want the Classic Premium Experience
Buy Oscietra. The flavour is the most distinctive of the three, the golden pearls present beautifully, and the price is manageable. Our Royal Oscietra is our flagship for a reason: it delivers the most caviar character per pound spent.
If You Are Hosting a Dinner Party or Tasting
Buy Baeri. A 100g tin serves six generously. Baeri holds up well in service, pairs with a wide range of accompaniments, and is the right choice when you want several guests to enjoy caviar without running into Beluga pricing.
If You Want to Try All Three
Our Beleaev Signature Tasting Set includes four of our caviars side by side, including Baeri, Oscietra, and Imperial (a rare golden-amber Oscietra variant). This is the single best way to understand the difference on your own palate.
How to Serve Any of the Three
All three caviars are served the same way. Chilled between zero and four degrees Celsius, over crushed ice, with a mother-of-pearl spoon. Traditional accompaniments are blinis, creme fraiche, chopped shallot, boiled egg yolk, and chives. For pairings, reach for a Champagne or a neutral vodka served very cold.
The portion guide is universal: 15 to 20g per person for a tasting portion, 30 to 50g per person for a main caviar course.

Frequently Asked Questions
Is Beluga actually worth the price?
For milestone occasions, yes. The texture and finish of Beluga are distinct and memorable. For everyday indulgence, Oscietra delivers most of the experience at a far more accessible price.
What is Imperial caviar and how does it fit?
Imperial refers to a rare golden-amber variant of Oscietra, hand-selected from mature fish for its striking colour and creamier flavour. Our Imperial Special Reserve sits between Oscietra and Beluga on flavour, with unique visual impact.
Which caviar is best for a gift?
Oscietra is the safest choice for a gift at most price points. Baeri in a gift set works well for a newer caviar recipient. Beluga is reserved for the most significant occasions.
Does the sturgeon species affect sustainability?
All three species are farmed at certified facilities under CITES regulations. Wild caviar is effectively unavailable in legitimate markets. Our suppliers provide full traceability on every tin.
Can I cook with any of these caviars?
No. All three are served cold, unheated. Heat destroys the texture and the subtle flavour. Caviar is a raw ingredient that completes a dish as a final garnish or sits on its own with blinis.
How much caviar should I buy per person?
Tasting portion: 15 to 20g per person. Generous portion: 30 to 50g per person. A 100g tin serves about four people generously, or six as a tasting.
What do you serve caviar with?
Classic accompaniments: blinis, creme fraiche, finely chopped shallot, boiled egg yolk, and chives. Keep the other flavours neutral so the caviar is the focus.
The Connoisseur's Choice
There is no single best caviar. There is only the right caviar for the right moment. Beluga for once-in-a-year celebrations. Oscietra for serious dining and memorable gifts.
