Agro Ittica Lombarda S.p.A. : CALVISIUSâ Original Caviar Malossol is the registered trade mark of Agroittica Lombarda's farmed White Sturgeon Caviar. Agroittica Lombarda, based in Brescia (Italy) runs the largest sturgeon farm in Europe producing 500 tonnes/year of meat and 20 tonnes/year of top quality caviar. Experienced since 1991 in farmed caviar processing, Agroittica has gained a worldwide reputation for the freshness, granulometry (min.2.8mm) flavour and hygiene of its sturgeon roe: a real Malossol with a very low salt content. This has been made possible because CALVISIUSâ is extracted from October through March thus avoiding high salting for longer preservation.
