Stabilizer Sulfiredox Laffort 1kg

Sulfiredox, developed by the renowned French company Laffort, is an aqueous copper sulphate solution intended for winemakers. Thanks to its oxidizing action on wine, the product removes light sulphur compounds, preventing and eliminating reductive notes and oxidation issues.

General principles of use

Sulfiredox is added to wine carefully and in controlled doses to neutralize unwanted sulphur compounds that may cause unpleasant odours. Copper sulphate reacts chemically with these compounds, rendering them odourless and improving the wine's aromatic profile. It is essential to follow recommended dosages to avoid excessive copper levels in the final product.
