After opening and storing the wine at 4 C, folate content fell
dramatically in both white (58%) and red (26%) wines by day 2,
with losses continuing up to day 5 (Table 2). An interesting observation was the fact that the greatest degradation in folate in both white and red wines after opening the bottle occurred in wines that had the lowest initial folate content. There was no correlation between the level of folate in the wine and total phenol and sulfite content. This result rules out the potential of having phenolic antioxidants and reducing capacity from sulfite as stabilizers for folate in the wine
