Yeast Energizer contains diammonium phosphate, yeast hulls, magnesium sulfate, and Vitamin B Complex to assist in the stimulation of fermentation. Recommended dose is 1/2 tsp. per gallon of wine mixed and added in during pretreatment of wine, or at time of yeast pitch.
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.
