Dealing With A Copper Problem
Roger Mattar Corona, California asks,
I have Syrah with H2S that I tried to take care of with a copper sulfate addition. After doing bench trials I found a solution but when I went to treat the entire batch I was rushing and ended up with 11 mL of 1% copper sulfate in a 15-gallon (57-L) batch. In the middle of the night I realized it was way too much. I have a 1-micron filter, would that help?
