Caviar is a globally renowned type of sea dish that has numerous health benefits. There is a wide variety of caviar to choose from. Let’s take a look at it in detail below.

What is Caviar?

A worldwide delicacy, caviar consists of ‘roe’ – a mass of small and delicate fish eggs. Traditionally, caviar is made from the eggs of sturgeon. In most commercial productions of this delicacy, the roe is extracted from a stunned female fish and then cured in salt. The soft and popping texture of the egg is considered a unique selling point of this luxurious dish. Salt and seaweed are the dominant flavors of caviar, but fresher varieties are less salty; the less salty it is, the more expensive it will be. Both the complicated extraction method and the short lifespan of caviar account for its high cost. Caviar is considered to be a good source for a range of vitamins and minerals such as vitamins A, B6, B12, and E, as well as iron, magnesium, and selenium.


There are many different types of caviar available in the market including beluga, sterlet, Kaluga hybrid, ossetra, American ossetra, Siberian sturgeon, and sevruga. Let us take a look at them below.

  • Beluga: This rarely caught fish produces generous-sized grey to black roe which is creamy and soft in flavor. The rarity of the fish places this caviar at the higher end of the price spectrum.
  • Sterlet: The roe from Sterlet Sturgeon are small and rich with a strong flavor.
  • Kaluga Hybrid: An ecologically minded alternative to Beluga, this fish is farm-raised and produces roe with similarly buttery characteristics to the Beluga roe.
  • Ossetra: Obtained from the Ossetra sturgeon and colored deep brown to warm gold, this caviar consists of medium-sized eggs and offers a fruity flavor.
  • American Ossetra: American ossetra are farm-raised, with the aim of preserving wild sturgeon and reducing the cost of caviar.
  • Siberian Sturgeon: A large, firm variety of this delicacy that has a nutty flavor and colors ranging from light brown to black.
  • Sevruga: This species produces small roe with a salty, rich taste. The fish that produces this roe are more plentiful than other sturgeons, and the price is therefore lower.
