Product Description

H2S, like boiled eggs or rotten eggs”

Certified beer flavour standard used to train professional beer tasters to recognize and scale the intensity of H2S character.

Hydrogen sulphide is produced by both ale and lager yeasts during fermentation. Contributes to perception of ‘fresh’ character at low levels – off-flavour when present in excess.

Food grade | Free from sensory impurities | Extensively tested | Safe to smell and taste.

IMPORTANCE

H2S is present in all beers. Concentrations vary considerably from beer to beer. H2S is an off-flavour in most beer styles. It is a signature flavour character in Burton ale.

ORIGINS

Hydrogen sulphide is produced by both ale and lager yeasts during fermentation and maturation. The amount of H2S produced and retained depends on wort composition, yeast strain and fermentation conditions.

HOW TO TASTE

The best way to detect hydrogen sulphide in beer is as follows. Without covering the glass, swirl the beer to release the aroma. Take a single short sniff. Repeat as necessary.

CAS NUMBER

The CAS registry number of hydrogen sulphide is 7783-06-4.
