Abstract

One of the important factors affecting wine fermentation is temperature. The influence of elevated temperatures from 10 to 25 °C at 5 °C intervals on yeast growth and fermentation products were studied in mixed cultures of Kloeckera apiculata and Saccharomyces cerevisiae in grape juice. In the experiments carried out at 10 and 15 °C, K. apiculata grew and survived longer compared to trials conducted above 20 °C. In most cases, higher temperatures stimulated the production of higher alcohols but lowered the formation of esters and acetaldehyde.
