Positively charged fining agent for beer and wine. Noted for working where other fining agents have failed. Also provides a compact sediment bed, pressing down other fining agents and increasing yield. Used as a coating medium for filter pads, to decrease porosity.
To use, stir 1/2 tsp. per gallon into one quart of briskly boiling water. Boil for three minutes, stirring well to completely dissolve. Use 1/2 cup of the prepared solution for every gallon of wine. Stir thoroughly into wine, leave for 2 weeks, and then rack off sediment.
