Research carried out by the Institute of Vine and Wine Sciences ISVV, has shown that wine oxidises in plastic bottles after six months.
The study took place after red and white Bordeaux wine, was packed into several different materials and stored in laboratory conditions while researchers analysed the levels of gases contained in the wine, along with its taste and colour intensity at regular intervals over a period of a year.
It revealed that white wines stored in the bag-in-box, single-layer PET and small multi-layer PET showed signs of oxidising after six months. Some initial signs were beginning to emerge in the red wine, but further study is required.
Rémy Ghidossi, lecturer at the ISVV, said: "A lot of contradictory information has been circulating in recent months regarding different packaging solutions suitable for wines. It is now necessary to establish the truth, based on scientific information and quantitative data, to determine the legitimacy of each package, as its main function is to preserve the flavour and characteristics of its content."http://tinyurl.com/34qszq7
