What two sturgeon species comprise the Kaluga Hybrid used to produce Kaluga Queen caviar?

Answer

The Kaluga sturgeon and the Amur sturgeon

Understanding the genetic composition of the source fish is fundamental to appreciating the product's unique characteristics. Kaluga Queen caviar originates primarily from the Kaluga Hybrid sturgeon. This hybrid is the result of carefully managed crossbreeding between the native Kaluga sturgeon and the Amur sturgeon. These fish are not sourced from the wild; they are part of an intensive aquaculture operation situated in China. The specific genetics derived from this hybrid pairing appear to be naturally conducive to developing the sought-after nutty complexity noted in the resulting eggs.
