Key Takeaways:
- True caviar comes from sturgeon, while eggs from salmon, trout, and other fish are generally called roe.
- Popular varieties include Ossetra, Kaluga hybrid, Sevruga, Siberian, white sturgeon, and Beluga.
- The sturgeon species helps determine the caviar’s pearl size, texture, color, and flavor.
People sometimes use “caviar” as a general name for fish eggs, but the term has a more specific meaning.
Different sturgeon species produce caviar with noticeably different pearl sizes, textures, colors, and flavors. Learning a few of the most common names can make choosing your first tin much easier.
What Is the Difference Between Caviar and Roe?
Fish roe is the broad term for fish eggs. Salmon roe, trout roe, lumpfish roe, and sturgeon roe all fall into this category.
Caviar is traditionally made from sturgeon roe. Salmon and trout eggs can still be delicious, but they offer a different experience. They’re usually larger and brighter in color than the darker, more nuanced pearls associated with sturgeon.
In the United States, the FDA says unqualified “caviar” should refer to salted sturgeon roe . Roe from another fish should include that fish’s name on the label, like “whitefish caviar.”
Which Sturgeon Fish Produce Caviar?
Several sturgeon species are raised for caviar. Each variety has its own character, so the name on the tin can tell you quite a bit about what to expect.
Ossetra Sturgeon
Ossetra caviar comes from the Russian sturgeon (Acipenser gueldenstaedtii). It is known for firm pearls and a rich flavor that may taste nutty, buttery, briny, or slightly mineral.
Royal Ossetra Caviar comes from this species. Its pearls range from golden brown to charcoal gray, with a bold oceanic taste and a lingering buttery finish. It’s a classic choice if you want caviar with a little more intensity.
Kaluga and Amur Sturgeon
Kaluga caviar comes from Huso dauricus, a large sturgeon native to the Amur River region. Many premium products sold today are Kaluga hybrids, created by crossing Kaluga with the Amur sturgeon (Acipenser schrenckii).
Hybrid Reserve Caviar comes from this pairing. It produces large pearls with dark amber, brown, or golden coloring. The flavor is smooth, balanced, and mild, making it especially approachable for a first tasting.
Sevruga Sturgeon
Sevruga caviar comes from Acipenser stellatus, also known as the starry sturgeon. Because Sevruga is a smaller species, it tends to produce smaller pearls.
Sevruga Reserve Caviar has fine gray to gray-brown pearls and a delicate, creamy character. Compared with the Ossetra or Kaluga hybrid, it offers a lighter texture and clean saline finish.
Siberian Sturgeon
Siberian caviar comes from Acipenser baerii. The species is widely raised in aquaculture, where caviar has become a primary reason for farming it.
Its pearls are generally small to medium in size. The flavor is often clean and gently briny, making Siberian caviar a welcoming option for first-time buyers.
What About White Sturgeon and Beluga?
White sturgeon caviar comes from Acipenser transmontanus, a species native to the Pacific coast of North America. It generally has medium-sized pearls, a firm texture, and a mild flavor.
Beluga caviar comes from the Huso huso species and is famous for its unusually large, delicate pearls. Because wild sturgeon populations have faced serious pressure, international trade in sturgeon products is regulated through conservation agreements.
Kaluga hybrid is now a popular option for buyers seeking a generous pearl size and smooth flavor from a farm-raised variety.
Does Caviar Come From Salmon or Trout?
Traditional caviar does not come from salmon or trout. Their eggs are called “roe,” although labels may use names such as “salmon caviar” or “trout caviar” when the fish is clearly identified.
Salmon and trout roe usually have bright orange or red pearls with a larger pop and a savory taste. Sturgeon caviar is generally darker and more subtle, with flavors that may feel buttery, nutty, or briny.
The difference isn’t a matter of quality. These products simply come from different fish and create different tasting experiences.
Why Does the Sturgeon Species Matter?
The species is one of the biggest factors shaping a caviar’s personality. It can influence the size, natural color, firmness, and flavor of the pearl.
Species isn’t the only factor. University of Florida researchers note that sturgeon egg size can also vary with heredity, age, and diet. Farming conditions, grading, salt level, packing, and freshness can all influence the finished caviar.
This is why two tins from the same general variety may not taste exactly alike. The species gives you a starting point, while the producer’s sourcing and handling shape the final experience.
Where Does Caviar Come From Today?
Historically, caviar was closely associated with wild sturgeon from the Caspian and Black Sea regions. Today, much of the premium caviar available online comes from managed sturgeon farms.
Farmed production provides an alternative to harvesting vulnerable wild sturgeon. International trade is also regulated by CITES, a treaty designed to ensure wildlife trade is legal, traceable, and biologically sustainable.
When buying caviar online, look for clear details about the species, source, storage requirements, and shipping process. A trusted seller should make it easy to understand what’s inside the tin and how it will stay chilled on the way to you.
Find the Caviar That Fits Your Taste
Caviar comes from sturgeon, but each species creates a slightly different experience. Ossetra, Kaluga hybrid, Sevruga, Siberian, white sturgeon, and Beluga all bring their own pearl size, texture, color, and flavor.
Start with the variety that sounds most appealing, or compare a few in a tasting set. Imperia Caviar makes it easier than ever to experience premium sturgeon caviar.
