(FIN320) A protein based clarifier that has been traditionally used by commercial wineries for many years. Preferred by some winemakers because of the softer, more gentle effect it has on the color and body of the wine. Very effective in adding a high polish to white and blush wines. Sufficient for treating 12 gallons of wine. Easy to use. Just stir in 1 oz. of liquid Isinglass into 5 or 6 gallons of wine and allow 3 to 4 days before bottling. Comes with complete directions.
