Table 1 Result of yeast (flow cytometric determination) and bacteria count (plate count onto MRS + TJ) performed during the 3 experimental winemaking. 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 = 6 in the case of yeast and n = 3 in the case of LAB)
