Caviar Varieties

There are an estimated 27 species of sturgeon, all of which are endangered, twelve of which are commercially fished or farmed, and five of which are known for producing the highest quality caviar, each named after the sturgeon species from which the eggs were harvested.


  1. Beluga* (Huso huso)
  2. Oscietra (Acipenser gueldenstaedtii)
  3. Kaluga (Huso dauricus))
  4. Sevruga (Acipenser stellatus)
  5. White Sturgeon (Acipenser transmontanus)


Caviar farming began to respond to declining wild sturgeon populations due to overfishing, habitat destruction, and, eventually, global-scale conservation efforts and regulations imposed by the United Nations-run Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).

Conservation regulations and trade restrictions, along with the unique specificities of different sturgeon species, the time it takes for them to produce Roe, and in some cases, such as that of the Beluga Sturgeon, from which the most sought-after caviar variety comes, the absolute bans imposed in some countries, brought about the exploration of sturgeon cross-breeding and subsequently introducing caviar hybrids to the market. 

Altima Caviar currently includes a Beluga Hybrid and a Kaluga Hybrid.

*A note on Beluga:

Before 2016, the absolute ban on Beluga-sturgeon products made Beluga Caviar unlawful in the United States. The closest consumers could get to the “Caviar of the Tsars,” was a Beluga Hybrid Caviar. In 2016, Aqua Farms was exempted from this ban, reintroducing sustainable Pure Beluga Caviar to the market.
