  • The Ripper Titration: Recent Improvements in Measuring SO2

    Another source of error that can lead to overestimation of free SO2 is the presence of other oxidizable compounds in the wine. These can react with the iodine titrant, again leading to overestimation of the SO2 level. In some white wines, there are appreciable levels of ascorbic acid which react readily with the titrant.
