  • SO2 Testing | MoreWine - MoreWineMaking.com

    SO2 testing is an integral part of winemaking and SO2 management begins as soon as you add sulfite to the wine. Having the right amount of SO2 in your wine prevents enzymatic browning and guards against premature oxidation. SO2 preserves freshness and color and it helps stabilize a wine against microbial spoilage.
