In the culinary world, two words that often get used interchangeably are roe and caviar. Both are fish eggs. Tiny, flavor-packed spheres that look very fancy at dinner parties. But are these two terms the same thing or is there a difference?

In this article, we’ll look at the difference between roe and caviar so that you’re armed with knowledge for that next upmarket cocktail party.

Roe Vs. Caviar – What’s The Difference?

Roe is a generic word to describe eggs from the ovaries of any variety of female fish or shellfish. Caviar is a type of roe that comes from sturgeon or other large fish. The scarcity of this fish makes it a costly delicacy that few get the privilege to eat.

It is usually quite easy to tell caviar and roe apart. Caviar appears black, grey or silver. Roe will often have an orange shade or some other bright color. Roe from salmon is called red caviar. They are large, orange balls that you regularly see on the sushi menu.

Tobiko is another very common roe. They are tiny, salty beads, often found as a garnish on sushi that appeals to fussy eaters. They come from flying fish with a texture that is almost crunchy as you bite into them. Tobiko can be colored a range of shades, including black (squid ink), red (beets), yellow (yuzu), and green wasabi).

On the supermarket shelf, there are plenty of low-cost jars of roe. These are harvested from common, sustainable fish varieties such as paddlefish, hackleback, capelin, or lumpfish. By law, the source of the eggs must be labeled on the jar.

Other types of roe popular in restaurants are bottarga, tuna, or mullet roe that gets dried and salt-cured. Their texture is firmer and can be shaved onto dishes.

Red Caviar
Red caviar is often salmon roe, a cheap alternative to real caviar.

Comparing the taste

Roe can vary in flavor depending on what seafood it comes from. The taste ranges from sweet through to briny with a buttery, fishy aftertaste. Although caviar has a similar fishy flavor, its texture is what people love. Like an everlasting gobstopper, those consuming caviar experience a journey: the initial texture is firm until the egg’s exterior melts and releases a soft, butter-like inside. The best caviar that is fresh will not have a salty taste; instead, it will be quite mild.

Types of caviar


Beluga sturgeon is rare on the menus in the United States due to overfishing and stock control policies. It is considered one of the best, if not, the best type of caviar on the market. Scarcity makes it highly desirable and very expensive. Beluga caviar is harvested exclusively in the Caspian Sea, a vast lake that borders a range of countries, including Russia, Iran, and Azerbaijan.

Their departure created a trend through Europe with everyone “wanting in” on the caviar action.
