Copper Sulfate 1oz

Some homewinemakers will treat wine affected with H2S by stirring with a copper rod or racking through a copper ‘scrubby’. Copper converts the the hydrogen sulfide into copper sulfide, which is not soluble in wine. After a few days the wine is racked off the copper sulfide which by that time has precipitated down to the bottom of your vessel. However, putting wine in direct contact with a non-measured amount of copper can result in residual copper being left in your wine, especially in low pH environments.
