Elimination of sulphide off-odours
Even though already at the end of the 19th century, sulphide off-flavours in wine were described for the first time, the development and above all, the prevention of sulphide off-flavours is still not yet finally cleared up today. The removal of sulphide off-flavours (which include hydrogen sulphide, mercaptan off-flavours and others), without greater quality losses, causes problems for the wine-maker every year anew. Kupzit is a product innovation to remove sulphide off-flavours very well without a metal flavour remaining in the wine. In most cases, a subsequent blue fining is not necessary. At present, Kupzit undergoes large-scale trialling in Austria. It is approved in Switzerland, New Zealand, Australia. From August 2009 Kupzit is it almost approved in th EU.
