THE FATE OF HUMULONE DURING WORT BOILING AND COOLING

Abstract

Variations in the nature of the grist, mashing temperature, gravity and content of anthocyanogens of wort influenced the yield of break obtained after boiling with humulone, but not the bitterness of the resulting worts. Only small amounts of resin were found on the break and although increased break formation resulted in increased adsorption of resin this did not lead to measurable differences in the bitterness of wort. The bitterness of the cooled wort was independent of the degree of aeration and speed of cooling. 1966 The Institute of Brewing & Distilling
