Sulphide Off-Flavour Removal in Red Wine
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.
Kupzit is an innovative product allowing for the effective removal of sulphide off-flavours without leaving a metallic note in the wine flavour. In most cases, a subsequent blue fining is not necessary. After intensive tests in many European regions Kupzit® is now approved all over the EU.
