Measurement of free SO2 content

Specialist laboratory test. 

Parameter: free SO₂ [g/L] 

Method, device:  Enzymatic method, automatic wine analyser (spectrophotometric).

Sample volume:  10 ml

The research report is issued in the English language.

The purpose of SO₂ is to prolong the shelf life of the wine being prepared - by inhibiting the growth of micro-organisms in the must or juice and counteracting oxidation processes (by inhibiting enzymes). By combining the measurement of free SO₂ with the measurement of the pH in the wine, we can plan such an addition of potassium metabisulphite to make our wine stable and lasting. Sulphur dioxide will also bind undesirable fermentation metabolites such as acetaldehyde.
