Ethyl carbamate is an undesirable trace component in distilledbeverages and its content in Scotch whisky is largely determined bythe cyanogenic pre‐cursor, epi‐heterodendrin(EPH) from malted barley. A rapid colorimetric procedurecan identify cultivars that do not produce EPH and attempts were madeto quantify this test, to determine differing levels of production.Using a given fresh weight of acrospire tissue from germinated grain,it was possible to distinguish between genotypes but differencesbetween replicates were substantial. Acrospire length was not areliable indicator of EPH production and genotypes differed not onlyin the quantity of EPH produced but in the rate and pattern ofproduction. © 1999 Society of Chemical Industry
