I have a barolo and amarosso juice bucket that just finished primary. I did not add nutrient and both now have a h2s smell. Please I know, lesson learned. Anyways I'm now concerned with correcting it. I'd prefer not to use copper sulfate. I was thinking of going to Home Depot tomorrow and getting a PVC pipe and some steel woolish product and pouring the wine to. Another option would be filtering it but I just started malolactic. Will his be effected?
