Russian Oscietra Caviar comes from the Russian sturgeon (Acipenser gueldenstaedtii), a prized species native to the Caspian and Black Seas. This caviar is harvested after a long maturation of about 10 years, which gives it a rich and complex aromatic profile. Its elegant and persistent flavor is appreciated for notes of dried fruit, butter, and a subtle hint of the sea. Characteristics: Diameter: medium, about 2.9–3.1 mm Color: from golden brown to dark gray Texture: firm and creamy Aroma and flavor: complex taste with notes of hazelnut, butter, and light marine nuances
