optimal temperature for yeast
EVERY DEGREE COUNTS Temperature is key to fermentation success 2 Yeast face a number of synergistic stress factors in ethanol production (Figure 1). Maintaining an ideal temperature range during the fermentation process is a diï¬cult task that all ethanol plant operators face, especially in the hotter months (Figure 2).The optimum temperature range for yeast fermentation is between 90ËF-95ËF (32ËC-35ËC).Every degree above this range depresses fermentation. While elevated temperature is problematic in all phases of ethanol production, it is speciï¬cally hazardous during the later stages of fermentation.VERY DEGREE COUNTS Temperature is key to fermentation success 2 Yeast face a number of synergistic stress factors in ethanol production (Figure 1).
