1% Copper Sulfate Solution - 4 oz
  • Add 1.5 ml per gallon of wine = 1.0 PPM Wait several days and retest. This dosage is the legal limit of residual copper allowed in wine by the TTB. If wine is clean, rack normally to remove copper.
  • If you find it necessary to add more than this dosage, follow the copper sulfate treatment with an addition of yeast hulls at 1-2 grams per gallon to remove excess copper. Wait 1 week and rack.
