Wine in bag-in-box and PET-bottles oxidise within 6 months, according to new study

Wine “bottled” (what do you say?) in bag-in-box, i.e. in a plastic bag, or in a lightweight plastic PET bottle is gaining in popularity, no doubt partially because of their lower weight and thus theoretically lesser impact on the environment. However, until today, no major scientific study has looked on how well the wine keeps in those containers, at least according to the press release announcing a new major scientific study on the subject.

It turns out that wine in BiB or plastic bottle starts becoming oxidised well within six months from ‘bottling’. The study analysed the wines chemically and also had a tasting panel taste them and the conclusion was that after six months the wines were noticeably oxidised. A control group of wines kept in glass bottle did not show signs of oxidations.

The study has been done by Institut des Sciences de la Vigne et du Vin (Institute of Vine and Wine Sciences of Bordeaux – ISVV) a research institute with links to the University of Bordeaux and to the French National Research Institute (INRA).
