  • Free SO2 Testing


    Sulphur Dioxide (SO2), an antioxidant, is one of the most important and effective chemical tools in winemaking. It inhibits molds and bacteria, and is an effective antioxidant, for which there is currently no suitable substitute.

     

    We carry all the equipment and reagents needed to conduct free sulfur dioxide (SO2) testing to confirm you are maintaining the necessary levels of free SO2 in your wine, whether you prefer to use Aeration Oxidation testing, or Accuvin Free SO2 Testing Kits.

     

    Many winemakers believe aeration oxidation is the most accurate way to test, but it does requires a laboratory apparatus set-up and some simple lab skills. See our Testing Free SO2 by Aeration Oxidation instructions for more information.

     

    Another very quick, accurate, and convenient alternative is the Accuvin Free SO2 Testing Kit, although these kits have a shorter shelf life than aeration oxidation reagents.
