Our Siberian Sturgeon are raised in large tanks of stone worked by locally sourced artisanal stonemasons, giving an authentically natural feel to the production site on land. This allows us to provide the most natural environment for our Sturgeon Species and produce the best caviar. STURS Premium Siberian Sturgeon Caviar has a delicate creamy pop to the roe with a lingering earthy note and buttery/ocean-like flavor finish.
