Kupzit - 100g to 1kg

Aim of Treatment

Kupzit® reacts quickly and specifically with sulphurous, disagreeably smelling compounds such as hydrogen sulphide and mercaptans. These compounds are precipitated and, when dosed accurately, increase the copper content of the beverage only insignificantly.

Dosage and Application

For an optimal treatment, pretests are absolutely recommended. Generally, the dosage amounts to 5-20 g/100 L; in exceptional cases up to 50 g/100 L or even more (observe laws and regulations of the individual country). Prepare a slurry of Kupzit ® and wine in a ratio of 1:10 then add. Provide for good distribution by stirring t horoughly. The reaction is completed within a few minutes after addition. Separation of the lees/sediments is conducted by filtration within 1-2 days. When applied properly, the copper content is not, or only slightly increased, which means in most cases after the Kupzit ® treatment blue fining is not required. Application can be conducted either separately or combined with clarification/fining. In case of a combined fining Kupzit ® is added as first component.

Storage

Store Kupzit ® in a dry and light-protected place. Protect fr om foreign odours. Reseal opened packagings tightly.
