Table 2 Chemical parameters of wines obtained by simultaneous fermentation of S. cerevisiae and L. plantarum or O. oeni at different temperature profiles. T1 test: 16/22 °C in 3 days, B. T2 test: 18/24 °C in 3 days, and C. T3 test: 22/32 °C in 5 days. (Mean, n = 3). *Differences are statistically significant both in terms of bacteria strain and temperature profile effect (two-way ANOVA test, p = 0.05).°Differences are statistically significant in terms of temperature effect (two-way ANOVA test, p = 0.05)
