Polish Antonius Caviar — 30g tin costs 1,030 zł, now Europe's largest caviar producer

Antonius Caviar, a Polish company established on the Łyna river, has grown into Europe's largest and the world's second-largest caviar producer. The river, too warm for trout, proved ideal for sturgeon farming. A 30-gram tin of the caviar retails for 1,030 złoty (around €240).
