A method for the determination of dimethyl sulphoxide (DMSO) in aqueous extracts is described. DMSO is reduced using stannous chloride and hydrochloric acid to dimethyl sulphide which can be measured by gas‐liquid chromatography. Other sulphur compounds, including S‐methyl methionine, have no effect on the assay. Levels of DMSO in solution higher than 10 μg litre −1 can be readily determined. In samples of brewery wort the levels of DMSO were within the range of 261‐411 μg DMSO litre −1 and repeated determinations on two samples of beer gave mean values of 417 and 627 μg DMSO litre −1 with coefficients of variation of 13.7 and 11.8% respectively.
