FORMULE 1-CF (Casein Free) prevents and treats the oxidation of casein free musts and wine. Made from PVPP and cellulose, using a unique coating and agglomeration techniques: granulation has a more even flow and is more homogeneous with fewer fine particles. The aggregates form more spaces and thus offer a larger physical adsorption surface area. This contributes to decreasing application rates. FORMULE 1-CF, in micro granules, can be used directly without any prior preparation.
