About this product
Black River Imperial Oscietra Caviar
Some caviars demand attention—this is one of them. We are proud to offer Imperial Oscietra from Black River Caviar, widely regarded as the finest sturgeon farm in the Americas and a global benchmark for quality.
Why Black River?
Founded in the early 1990s, Black River was the first sturgeon farm in the southern hemisphere. Using broodstock originally sourced from the Caspian Sea, the farm focuses exclusively on Oscietra.
Set in a remote, pristine environment in Uruguay, the sturgeon are “wild farmed.” For their first four years, they swim freely in netted enclosures in Lake Baygorria, part of the Río Negro. They are then transferred to flowing raceway basins designed to replicate natural river conditions, with 50 million gallons of fresh water passing through daily.
Production is deliberately limited to just four tonnes per year, with an uncompromising focus on quality over quantity.
Why Imperial Grade?
Black River produces three grades of Oscietra. We import only the highest: Imperial.
