Abstract
The impact of serial repitching on dynamics and effects of HG (16%) and VHG (20%) wort fermentations was examined. It was observed that top-fermenting brewing yeasts (S. cerevisiae I-S.c./57) had a better fermentation activity than bottom-fermenting strain (S. carlsbergensis I-S.ca./13). Yeasts maintained good dynamics during serial re-pitching fermentations of 16% worts. Increase of wort concentration up to 20% had a negative influence on dynamics and extract attenuation in serial repitching processes.
