IS 15
IS 15 is a soluble powdered gelatin. It contains medium molecular weight proteins. 80% of these proteins have a molecular weight equal to 15 000 Da. It is used to rapidly fine tannic red wines with minimal lees volume.
IS 15 has a high reactivity with bitter and astringent tannins. This gelatin ensures a perfect limpidity without modifying wines’ organoleptic qualities.
