These aromas are conferred by a range of hop-related volatile compounds, including polyfunctional thiols such as 3-sulfanylhexan-1-ol (3SH) and 4-methyl-4-sulfanylpentan-2-one (4MSP). These compounds are present at relatively high concentrations in hops and are extracted into beer during dry-hopping. Polyfunctional thiols are also abundant as non-volatile glutathione and cysteine conjugates in hops, and to a lesser extent can be found in barley (and therefore, malt). These conjugates are cleaved into amino acids and free thiols by enzymatic activity of yeasts, thus bound precursors may represent...
