Osetra is known for its golden hues and nutty, buttery flavor. Osetra caviar comes exclusively from Russian sturgeon (Acipenser gueldenstaedtii). This sturgeon species is native to the Caspian Sea. Caspian Sea caviar, particularly Beluga and Osetra, are considered the best in the world. Due to overfishing and poaching, the Caspian Sea native sturgeon species are all critically endangered. They are no longer legal to capture in the wild. All Osetra caviar on the legal market is currently farmed. Russian sturgeon must reach at least 7 years old before they produce their first roe. The long wait coupled by the unique and complex flavor, color and firm texture, makes Osetra caviar the second most coveted caviar on the planet (Beluga being first, yet highly unattainable due to it 14-16 year maturation wait).
