ORGANOLEPTIC THRESHOLD VALUES OF SOME ALCOHOLS AND ESTERS IN BEER

Abstract

In a Norwegian all-malt pilsener beer the organoleptic threshold values were determined for the following alcohols and esters: n-propanol, isobutanol, amyl alcohols (2-methyl butanol + 3-methyl butanol), 2-phenyl ethanol, ethyl acetate, isobutyl acetate, iso-amyl acetate, 2-phenyl ethyl acetate, ethyl caproate and ethyl caprylate. In addition, threshold values for a number of combinations of these alcohols and esters were determined, and in each case an additive effect was found.
