The species Baerii is the most popular caviar in Europe and in the world, because it comes from a sturgeon living in the rivers that adapts well to captivity and at all latitudes. It is found in Belgium, Germany, Italy, Finland, China, France under the name of Aquitaine. Originally from Siberia, it is one of the smallest sturgeons, its weight rarely exceeding 10 kilos.
The Baerii caviar is close in appearance and texture to the grain of the Sevruga caviar. It is cheaper without forfeiting either the eye nor the palate. Medium to small size, its gray to light gray eggs joyously burst in the mouth, leaving a sweet, nutty flavor.
