WebMar 22, 2024 · The tannin content before fermentation was the highest in the LOT (6.05 ± 0.14 ppm) and the lowest in the FOT (0.57 ± 0.03 ppm). The tannin value gradually decreased after the LOT fermentation and increased significantly in Week 8, reaching a maximum value of 6.79 ± 0.81 ppm in Week 9.
