Sparkolloid is a cellulose/diatomaceous earth mixture that is effective in clarifying wine. Use by slowly adding 1/2 tsp. of Sparkolloid per gallon of wine to 1-1 1/2 cups of boiling water, stirring until smooth and creamy. Next, add this mixture to the finished wine and stir. Let settle for 1 week or more, then filter or rack off from the top, leaving the sediment behind.
