Values are shown as mean ± SD of three biological replicates. The glucose and fructose contents of the natural must in the fermentations were ranged in 190.4–195.8 g/L. Different letters indicate statistically significant differences (HSD Tukey) for values in the same column

ND not detectable

¹Analyses were performed after 4 days of fermentation
