Plastic bottles & bag-in-box packaging may be not be as good for storing wine as originally thought, according to a new study by Bordeaux's Institute of Vine & Wine Sciences (ISVV). White wine was significantly altered after just 6 months in bag-in-box, mono PET & PET multi bottles, according to researchers at the ISVV, which is one of Europe's largest wine research centres. Initial results from the study throw doubt onto claims by some manufacturers & retailers that plastic bottles can preserve a wine's characteristics for up to one year. "After 12 months, white wine is fully oxidised," said the researchers, who are one year in to a two-year investigation. "The glass bottle preserves white wine's original characteristics with stability," they added. The report concluded: White Wine - Bag-in-box, mono PET and PET multi bottles significantly affect white wine's characteristics (oxidation process), even after a short 9 month period. The glass bottle preserves white wine's original characteristics with stability. After 12 months, white wine is fully oxidised. The panel of professional and standard tasters all agree on its chew fruits flavour. Red Wine - The results to date begin to show changes but they do not allow significant conclusions to be drawn from an olfactory point of view.
