Wine Free SO2

The analysis of free SO2 in a wine product measures the amount of SO2 that is not chemically bound in solution and therefore available and active as a microbial inhibitor. Total SO2 content, in combination with the Free SO2 content, provides a complete picture of the preservative capacity of the sulphur dioxide in a wine. It is recommended that Free and Total SO2 be ordered at the same time.
