Sparkolloid Fining Agent
  Sparkolloid is a fining agent developed by Scott Laboratories for clarification. It is a blend of polysaccharides in a diatomaceous earth carrier and has a strong positive charge. For some, it is the product of choice for clarifying white and blush wines. Sparkolloid is one of the more benign fining materials, and when used in reasonable quantities, it seldom strips wine flavors or aromas. It neutralizes the repelling charge of particulate matter allowing aggregation and formation of compact lees. It does not remove desirable color constituents. It is not a cold stabilizing, heat stabilizing or odor removing agent. 1 tsp. per gallon clarifies naturally by removing protein haze.
  To prepare for adding, it is recommended to use distilled water distilled water. Bring 2 cups to boiling and stir in 1 tsp. per gallon of Sparkolloid. Stir frequently, maintain the mixture at about 180*F. Sparkolloid contains some filter aids that will not dissolve. These particles will be adequately distributed by constant stirring as it is being heated. Agitating the mixture constantly is important. When all the globulues of clarifier have gone into suspension and the mixture is smooth and creamy (about 15 minutes), Slowly stir the Hot Sparkolloid into the wine to be clarified. Sparkolloid produces very fine lees, and the lees settle out of the wine slowly. Consequently, this material should not be used less than 30 days before bottling time, or small amounts may precipitate later in the bottles. Many winemakers allow for an eight-week settling time just to be on the safe side.
