The free sulphurous anhydride is titrated directly in wine with a titrated iodine solution in the presence of a starch indicator. Subsequently, and on a second sample, the SO2 is released from the combinations it forms thanks to an alkaline solution. Then, the same titration as above is done again and total SO2 is obtained. The difference between the 2 results gives the combined SO2.

The sulphurous anhydride is a dissolved gas, which constantly escapes from liquid. To minimize this loss, it is important to: 
- Carefully take the sample, cork it immediately, and keep it at a cool place after analysis. 
- Prepare the material and the products before uncorking the sample.
- Quickly measure the sample and proceed immediately to titration.
