This Caviar House Thousand Island Lake Osega Caviar is made from purebred Russian sturgeon. The roe has a distinctive amber to brownish-green hue, a moderate firmness, and is easy to shape, making it an ideal choice for high-end dining presentation. Compared to more common hybrid caviar, its roe, while more refined, possesses a deeper, more delicate buttery aroma and multi-layered marine flavor.
