Sparkolloid is by far, our most popular and effective wine clarifier. It is our first line of defense against cloudy wine.
Mix one tablespoon of sparkalloid into 1 cup of boiling water. Boil for 15 minutes, stirring occasionally. While solution is still warm, mix or turkey-baste the boiling liquid into 6 gallons of wine and stir gently. Let settle. For best results, wait at least a month before VERY CAREFULLY racking the crystal clear wine off of the cloudy dregs at the bottom.
