Potassium Caseinate (Kolorfine), powder.
Used with white wines to clarify and to reduce oxidized odors and freshen the wine. It will also remove some brownish color pigments.
To prepare, hydrate in water for 2 to 3 hours and add to the wine while vigorously stirring since it will coagulate in acidic solutions in a few seconds.
Typical dose is 1 to 2 grams per gallon, but as much as 3 grams per gallon when color is the main problem.
