What Are the Special Features of Each Caviar?

Caviar has long been synonymous with luxury, evoking images of elegant dinners and refined palates. However, what truly sets this delicacy apart is the unique features of each caviar, which stem from the sturgeon species, their habitats, and the meticulous processing methods. Whether it’s the buttery smoothness of one variety or the bold brininess of another, understanding these unique traits can transform your appreciation of caviar from mere indulgence to an informed culinary adventure. In this guide, we’ll explore the special features of each caviar, drawing on the latest insights from sustainable sourcing and gourmet trends as of 2025. Perfect for beginners and enthusiasts alike, we’ll break it down simply, highlighting origins, flavours, textures, and what makes each one stand out.

Caviar, at its core, refers to the salt-cured roe (eggs) of sturgeon fish, though some alternatives from other species are gaining popularity. Traditionally harvested from the Caspian Sea region, overfishing has led to a shift towards sustainable aquaculture worldwide. This ensures that we can enjoy these treasures without harming endangered populations. Prices vary widely, from affordable options around £30 per ounce to rarities exceeding £200, influenced by rarity, egg size, and quality. Let’s dive into the types, starting with the classics.

Beluga Caviar: The Pinnacle of Creamy Elegance

Beluga caviar is often hailed as the king of caviars, and its special features lie in its extraordinarily large, soft eggs that deliver an unparalleled creamy texture. Sourced from the beluga sturgeon (Huso huso), native to the Caspian Sea, these fish can grow up to 20 feet long and take over 15 years to mature, making this variety exceptionally rare. The eggs are pea-sized, ranging in colour from pale silver-grey to deep black, with a glossy, pearl-like sheen.

What makes Beluga truly special is its flavour profile: buttery and rich, with subtle hazelnut notes and minimal fishiness. When you pop these delicate orbs on your tongue, they melt almost instantly, releasing a luxurious creaminess that’s both indulgent and refined. This texture is due to the high fat content in the eggs, setting it apart from firmer varieties.

However, sustainability is key here. Wild beluga sturgeon are endangered, leading to import bans in places like the United States since 2005. Today, much of the supply comes from farms, ensuring ethical production. Priced at £200-£300 per ounce, it’s best served simply, on a mother-of-pearl spoon or the back of your hand, to savour its purity. Pair it with chilled vodka or champagne for a classic experience. For those new to caviar, Beluga’s mildness makes it an inviting entry point, though its cost reserves it for special occasions. You can see the price of Beluga caviar at Culture Caviar.

Ossetra Caviar: Nutty Depth with a Royal Touch

Moving to Ossetra (also spelled Osetra), one of the special features of this caviar is its complex nutty flavour combined with a firm yet popping texture that bursts with oceanic brightness. Harvested from the Ossetra sturgeon (Acipenser gueldenstaedtii), originally from the Caspian Sea but now mostly farmed sustainably in regions like China and Europe, this variety offers eggs that are medium-sized and vary in colour from golden yellow to dark brown or even greenish hues.

The standout trait is the flavour: a harmonious blend of buttery nuttiness, subtle brininess, and hints of citrus or seaweed, creating a multi-layered taste that evolves on the palate. Unlike Beluga’s softness, Ossetra eggs have a resilient snap, providing a satisfying mouthfeel. Historically, the lightest golden Ossetra was reserved for royalty, earning it the nickname “imperial caviar.” Royal Ossetra Impérial Caviar is available at Culture Caviar.

Affordability is another perk, with prices ranging from £50-£175 per ounce, making it accessible for everyday luxury. Sustainability efforts have boosted its availability, with farms focusing on eco-friendly practices to protect the endangered wild stocks. Serve Ossetra on blinis with crème fraîche for a balanced bite, or use it to elevate seafood dishes. Its versatility and depth make it a favourite among chefs and home cooks alike, appealing to those who crave a more pronounced sea essence without overwhelming intensity.

Sevruga Caviar: Intense Brininess in a Compact Package

Sevruga caviar’s special features are its small, crisp eggs that pack an intense, full-bodied brininess, offering a bold contrast to larger, milder varieties. Derived from the sevruga sturgeon (Acipenser stellatus), found in the Caspian, Black, and Aegean Seas, these eggs are the smallest among the premium types, typically steel grey to dark charcoal in colour with a fine, jade-like appearance.

The flavour is assertive: deeply salty with nutty undertones and a clean, crisp finish that lingers refreshingly. This intensity comes from the sturgeon’s faster maturation cycle, allowing for more concentrated tastes. The texture is firmer and crunchier, providing a delightful pop that enhances its vibrancy.

Priced at £50-£120 per ounce, Sevruga caviar is one of the more budget-friendly luxuries, thanks to sustainable farming initiatives that have revived populations after overfishing threats. It’s ideal for those who enjoy robust flavours, perhaps paired with neutral bases like unsalted crackers or in gourmet canapés. In fine dining, it’s often used as a garnish for its striking colour and punchy profile. For beginners, start small to appreciate its power; it’s like the espresso of caviars, concentrated and invigorating. Sevruga classic is also available in our wholesale caviar service for fine dining restaurants and bars.

Kaluga Caviar: The Sustainable Giant with Buttery Salinity

Known as “River Beluga,” Kaluga caviar’s special features are its large, glossy eggs that mimic Beluga’s luxury but with a more pronounced salty edge, making it a sustainable alternative. Sourced from the Kaluga sturgeon (Huso dauricus) or hybrids, native to Asian river basins like the Amur, this variety thrives in aquaculture, reducing pressure on wild stocks.

Eggs are substantial, coloured from dark grey to light brown or golden, with a firm yet melting texture that releases buttery, earthy notes laced with brine. This balance of size and salinity sets it apart, offering Beluga-like indulgence without the rarity. Flavours include nutty richness and a subtle sweetness, perfect for pairing with seafood.

At £65-£85 per ounce, it’s reasonably priced due to farming efficiency. Sustainability is a highlight, with CITES regulations ensuring ethical trade. Enjoy it straight or on toast points; its robustness suits casual gatherings or as an introduction to high-end caviars for eco-conscious diners.

Sterlet Caviar: Subtle Mildness in a Pearlescent Gem

Sterlet caviar stands out for its small, golden-hued eggs that deliver a mild, buttery flavour with sweet undertones, once reserved for tsars and emperors. From the sterlet sturgeon (Acipenser ruthenus), native to European and Siberian rivers, it’s rare due to the fish’s endangered status, but farmed versions are emerging.

The eggs are tiny and pearlescent grey to golden, with a smooth, silky texture that glides on the palate. Its special features are the understated elegance—nutty and less briny than others, making it approachable for novices.

Costing £50-£100 per ounce, it’s exclusive yet not exorbitant. Sustainability focuses on aquaculture to combat overfishing. Serve as a garnish on salads or pasta for a touch of sophistication; its delicacy shines in lighter pairings.

Hackleback Caviar: American Boldness with Earthy Notes

Hackleback’s special features are its firm, jet-black eggs bursting with sweet, nutty intensity, representing America’s contribution to caviar. Harvested from the shovelnose sturgeon in U.S. rivers like the Mississippi, it’s wild-caught but regulated for sustainability.

Flavours are deep and earthy, with a glossy texture that’s resilient and popping. Priced at £35-£45 per ounce, it’s the most affordable premium option. Ideal for garnishing appetisers or blending into dips, it appeals to those seeking bold tastes without the fuss.

Siberian or Baerii Caviar: Briny Black Pearls from the North

Siberian caviar’s special feature is its medium black beads with high brine content, offering a straightforward, authentic sturgeon taste. From the Siberian sturgeon (Acipenser baerii), farmed in colder climates, it matures quickly for consistent supply. Baerii caviar’s flavours are clean and salty, with a firm texture. Baerii caviar is Affordable at around £40-£60 per ounce, it’s sustainable and versatile for everyday use. You can pair our Royal Baerii Caviar with potatoes or eggs for a hearty twist.

Alternative Caviars: Beyond Sturgeon for Accessibility

While traditional caviar is sturgeon-based, alternatives like salmon roe (ikura) feature large, orange eggs with juicy, salty pops; perfect for sushi. Trout roe adds smoky sweetness, and paddlefish offers mild firmness. These are cheaper (£10-£30 per ounce) and sustainable, broadening caviar’s appeal.

Hybrid Caviar: Blending the Best of Both Worlds

Hybrid caviar’s special features lie in its unique combination of traits from crossbred sturgeon species, offering novel flavours. Created by breeding sturgeons like Kaluga with beluga or Siberian with Ossetra, hybrids combine the best qualities of their parents, balancing texture, size, and taste.

For example, Kaluga-beluga hybrids produce large eggs with Beluga’s creamy softness and Kaluga’s salty earthiness, creating a rich yet balanced profile. Siberian-Ossetra crosses yield medium-sized eggs with Ossetra’s nutty complexity and Siberian’s briny punch. Colours range from golden to dark grey, depending on the cross. The texture often balances a firm pop with a creamy finish.

The standout advantage is sustainability. Hybrids mature faster than purebred sturgeons, reducing farming time and environmental impact. They’re also more resilient, making them easier to produce in aquaculture. Priced at £60-£150 per ounce, hybrids are a cost-effective luxury, blending premium qualities with accessibility. They’re perfect for adventurous eaters, served on crackers or in creative dishes like caviar-topped sushi. Their eco-friendly appeal makes them a rising star in 2025’s gourmet scene. At Culture Caviar, we also produce high-quality hybrid caviar, which comes from a cross between the sturgeon species “Acipenser Schrenckii” and “Huso Dauricus”.
