Copper Sulphate 1 oz

Copper sulphate 1 oz for reducing hydrogen sulfide (H2S) — the rotten egg off-odor — in wine. A 1% copper sulfate solution applied in precise measured amounts is a professional-grade approach to eliminating H2S without harsh treatment.

Use a bench trial to determine the minimum effective dose before treating the full batch. Apply with a pipette for precise measurement. Always use the least amount necessary to eliminate the problem.
