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. WebUsing calcium alginate-entrapped yeast, 24% (w/w) wort was successfully fermented within 8 days. This is half the time needed for fermentation by free yeast. The highest ethanol concentration obtained was 10.5% (v/v). When the original wort gravity was increased, the specific rate of ethanol production remained constant 0.16 g gh−1 and the viability did …
