(a) Density (g/L); (b) Yeast population of non-Saccharomyces; (c) Yeast population of Sc23 and (d) Ethanol production (%, v/v) and yield (g/g) during sequential fermentations in natural must. The value of the green line in Figure (d) is 0.49 g/g (ethanol yield of Sc23). Asterisks (*) show the significant difference of ethanol yield compared with Sc23 (LSD, p < 0.05).
