They have the disadvantages, however, of producing high levels of acetic acid, lacking vigor, and not completing the fermentation process, thereby leaving high levels of residual sugar. Despite the many negative traits, which make them enologically unsuitable, the thermotolerant Saccharomyces cerevisiae strains demonstrate potential for enological applications and provide a valuable genetic resource for yeast improvement programs.
