Antonius Siberian Caviar comes from females about 8 years old. Opening the tin reveals average grains of about 2.3-2.6mm. Siberian caviar glistens with black ebony reflections and has an earthy aroma. In the mouth, its delicate, yet firm pearls overtake your mouth and leave notes of earth, minerals, and wild flora. It has a deeper, more complex sturgeon flavour.
