Derived from algae, this clarifier is good for reducing haze-causing proteins in light wines. Mix one teaspoon per gallon of wine into 1 or 2 cups of boiling water. Boil for 15 minutes, stirring occasionally. While solution is still warm, mix into 6 gallons of wine and stir gently. For best results, wait at least a month before bottling. Sparkolloid will keep for 6 months or more.
