The producer
Why it matters.
As the first Southern Hemisphere caviar farm, Black River pairs unusual river-fed provenance with end-to-end lot traceability and production control.
The origin.
Black River Caviar, operated by Esturiones del Río Negro, uses gravity-fed raceways and open-water enclosures along Uruguay's Río Negro to raise, harvest, cure, grade, and mature Russian Oscietra caviar.
