Significance of DMSO in the brewing process
The relevance of dimethyl sulfoxide (DMSO) as a precursor of dimethyl sulfide (DMS) is discussed in the following contribution. It explains the theoretical background to formation of DMSO as well as its reduction to free DMS during beer fermentation. As a starting point for further scientific brewing investigations, this part also includes an overview of DMSO concentrations in various malt types.
