this great video and write-up about a South Korean Caviar Farm that has been raising sturgeon in their facilities including albino sturgeon.
Albino Sturgeon are very rare and their caviar (Sometimes referred to "Almas Caviar" is some of the most sought after caviar in the world. With wild varieties fetching prices over $3,000 an ounce, albino "almas" caviar is surely the most expensive caviar in the world.
Although farm-raised, prices of the albino sturgeon from South Korea are sure to fetch astronomical prices. Would love to try some of their products, and perhaps give them a visit!
