Product Description

DMS, like boiled sweetcorn or tomato sauce”

Certified beer flavour standard used to train professional beer tasters to recognize and scale the intensity of DMS character.

Dimethyl sulphide is formed from thermal degradation of malt-derived precursors and to a lesser extent from metabolism of brewer’s yeast. It can also be formed by bacterial contaminants.

Food grade | free from sensory impurities | extensively tested | safe to smell and taste.

IMPORTANCE

DMS is a desirable flavour in some pale lager beers and ales and an off-flavour in other beers. Excessive levels of DMS are indicative of growth of contaminant bacteria during fermentation.

ORIGINS

Dimethyl sulphide is formed from malt-derived precursors (S-methyl methionine and dimethyl sulphoxide), primarily during wort production and – to a lesser extent – during fermentation.

HOW TO TASTE

The best way to evaluate dimethyl sulphide in beer is to swirl the sample to release the aroma and then take a single short sniff.

CAS NUMBER

The CAS registry number of dimethyl sulphide is 75-18-3.
