Made from the white fish roe of the rare albino sturgeon; the manufacturers first dehydrate and finely grind the white roe. However, this alone doesn't warrant the extravagant mark-up price: 22 carat gold leaf is sprinkled into to the caviar, which the business has dubbed "gold strottarga" or "white gold" caviar.
"It's certainly not a product for everyone, but the market is crying out for new and absolutely exquisite products that chefs around the world can offer their guests" said, Walter Grüll, according to a regional news source in Austria. He added that the "golden-white shimmering powder" works best with pasta, risotto or on toast.
To create only one kilogram of the "white gold" product, five kilograms of raw white caviar are needed as 80 percent is lost during dehydration.
The "white gold" caviar has been created by Salzburg fish farmer, Walter Grüll and his son Patrick, who own 'Grüll fish trade' business, in Salzburg, Austria. The family business is Austria's first sturgeon caviar producer, and the company is one of the almost 30 breeders of sturgeon, in the world. It takes eight to 10 years for a sturgeon to be "ready to harvest" according to its website.
