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. 1972 The Institute of Brewing & Distilling
