Standing in front of four tins of black caviar for the first time is a strangely intimidating experience. All four are called “caviar.” All four are, technically, sturgeon roe. Yet the price can vary five-fold between them, the flavours are genuinely and distinctly different, and the “right” choice depends entirely on who is asking and why.

This guide compares the four sturgeon varieties available at London Caviar House — Beluga, Osetra, Sterlet and Bester — across the criteria that actually matter when choosing: flavour, egg size, price position and occasion. By the end, you should have a clear sense of which caviar is right for you, whether you are buying your first tin or expanding an already well-stocked collection.

At a Glance

The Four Varieties at a Glance

The Legend

Beluga — The Legend

Beluga is the caviar against which every other caviar is measured. It comes from Huso Huso, the largest freshwater fish on earth, and it takes 15 to 25 years for a female to reach the maturity required to produce eggs of commercial quality. The eggs themselves are the largest of any commercial caviar — pale grey, lustrous, and famous for a flavour that is delicate rather than intense: creamy, subtly briny, with a long, elegant finish that lingers on the palate rather than announcing itself immediately.

Served simply — chilled, on a mother-of-pearl spoon, with nothing to distract from it — Beluga is often described as the closest thing caviar has to a meditative experience. This combination of extreme rarity, decades-long production and an unmistakably refined flavour is why Beluga has been the definitive symbol of culinary luxury for three centuries. It is available at London Caviar House in both our Classic and Premium ranges, including the exceptional grade 000 for those seeking the very largest, most mature eggs. For a full breakdown of current pricing, see our complete Beluga caviar price guide.

The Connoisseur’s Choice

Osetra (Russian Sturgeon) — The Connoisseur’s Everyday Choice

If Beluga is the legend, Osetra is the caviar that serious buyers actually reach for most often. Its eggs are medium-sized, firm, and golden-grey to brown in colour, with a flavour that is noticeably more complex than Beluga — nutty, briny, with distinct notes some tasters compare to the sea itself or to walnut skin. Where Beluga is famous for subtlety, Osetra is famous for character, and it holds its own beautifully alongside stronger accompaniments and bolder wine pairings.

Osetra typically sits at 40 to 60 percent of the price of equivalent Beluga, which makes it the variety most regular caviar buyers settle on for ongoing enjoyment rather than occasional indulgence. It rewards repeated tasting — many connoisseurs find they notice new dimensions of flavour with each encounter, which is part of why it has such a loyal following among people who buy caviar regularly rather than for special occasions alone. Browse our Classic Osetra caviar or explore the full Premium range.

The Tsar’s Caviar

Sterlet — The Tsar’s Caviar

Sterlet has a history unlike any other caviar on this list. For centuries it was reserved almost exclusively for the Russian imperial court — Peter the Great was a documented enthusiast — and it remains, in character, the most aristocratic of the four varieties. The eggs are the smallest and darkest of the group, with an exquisitely refined, subtle flavour that is easy to underestimate on a first taste and genuinely rewarding on a second and third.

Sterlet reaches maturity considerably faster than Beluga, which — combined with its smaller size — makes it the most accessible entry point into premium black caviar at London Caviar House, typically priced at 25 to 40 percent of equivalent Beluga. For anyone curious about black caviar but hesitant about the investment a Beluga tin represents, Sterlet is very often the right place to begin, and its refinement means it never feels like a compromise. See our Classic Sterlet caviar.

The Hybrid

Bester — The Hybrid Innovation

Bester is the variety most first-time buyers have never heard of — and it deserves far more attention than it typically receives. Bester is not a naturally occurring species; it is a purposefully bred hybrid, first developed by Russian aquaculture scientists in the mid-twentieth century by crossing Beluga with Sterlet. The goal was to combine the best characteristics of both: the large, impressive eggs and prestige of Beluga, with the faster maturation and refined finesse of Sterlet.

The result genuinely delivers on that promise. Bester produces medium-to-large eggs with a distinctive, balanced flavour that sits between its two parent species — more character than pure Beluga, more size and presence than pure Sterlet. Its price typically falls between Beluga and Osetra, making it a fascinating and slightly unusual choice for buyers who already know the other three varieties and want to try something genuinely different at their next dinner party.

Choosing by Flavour

How to Choose: By Flavour

If flavour is your primary consideration, it helps to think of the four varieties along a spectrum. At one end sits delicate and subtle — Beluga and Sterlet both live here, prioritising elegance and a long, gentle finish over immediate intensity. At the other end sits complex and pronounced — Osetra’s nutty, briny character is the most assertive of the four. Bester sits in the middle, offering a genuine balance between the two extremes.

Buyers new to black caviar often assume they will prefer the most intense flavour, but in practice many discover they prefer the subtlety of Beluga or Sterlet once they have tasted both ends of the spectrum. This is precisely why tasting more than one variety before committing to a large tin is worthwhile — palate preference in caviar is genuinely personal, and it is very difficult to predict in advance.

Choosing by Occasion

How to Choose: By Occasion and Budget

First-time buyer or smaller budget: Start with Sterlet, or better still, a tasting set that lets you sample multiple varieties in one sitting without committing to a single choice.

Best everyday value for regular enjoyment: Osetra is the choice most experienced buyers settle into — genuine premium character at a more sustainable price for frequent indulgence, whether that means a Friday evening treat or a standing feature at dinner parties.

A grand occasion, milestone or statement purchase: Beluga remains unrivalled. When the moment calls for the single most prestigious food available — an anniversary, a landmark birthday, an engagement — nothing else compares.

Something distinctive to share and discuss: Bester is a genuine conversation piece — few guests will have tried it, and its backstory as a deliberately engineered hybrid makes for excellent dinner table conversation alongside excellent flavour.

Caviar as a Gift

Caviar as a Gift: Matching Variety to Recipient

Choosing caviar as a gift adds another layer to the decision. For a client or senior colleague, Premium Beluga makes an unambiguous statement of respect and generosity. For a close friend or family member who already loves fine food, Osetra or Bester often lands better — distinctive and interesting rather than simply the most expensive option available. For someone entirely new to caviar, a tasting set or a Sterlet tin is a thoughtful way to introduce them without overwhelming them on their first encounter. Our full caviar gift sets range includes options built around several of these varieties, beautifully presented and ready to give.

Classic vs Premium

Classic or Premium? Remember You Have Two Options for Each

Whichever variety you choose, you will also choose between our two production methods. Premium caviar is harvested using the traditional method. Classic caviar is harvested using the humane no-kill milking method, in which the sturgeon survives and can produce again in future seasons — a difference that is reflected in a lower price without any compromise in flavour or quality. You can read the full explanation of how the method works in our guide to Classic caviar and the milking method.
