WebAbstract The performance of yeast is often limited by the constantly changing environmental conditions present during high-gravity fermentation. Poor yeast performance contributes to incomplete and slow utilization of the main fermentable sugars which can lead to flavour problems in beer production. WebIndeed, it is well-known that the use of worts of high specific gravity results in disproportionate amounts of esters. In contrast to high-gravity brewing, fermentations in tall 'Apollo' fermentors or the production of low alcohol beers result in a reduction of ester formation, so that the produced beers lack desirable fruity tones.
