Abstract The inhibitory effects of ethanol and substrate sugars (glucose, fructose, and mixtures of glucose plus fructose) on the growth of two strains of Saccharomyces yeast have been compared at equivalent values of overall water activity aw. For one yeast strain (UQM 66Y), the inhibition by both ethanol and sugars was almost identical at equivalent values of aw. For the second strain (UQM 70Y), the inhibition by ethanol was significantly greater. The results imply that the mode of action of ethanol on yeast growth can be divided into non-specific effects, which are characterized by reduced water activity, and specific effects, where the solvent acts against the cell membranes and particular enzymes. Sugar molecules, on the other hand, act almost totally in a non-specific manner.
