We’ve been seeing more and more wine companies considering plastic wine bottles as a greener alternative to glass. The bottles are lighter and 100 percent recyclable. One Australian producer, Wolf Blass creates a line called "Green Label" that uses these lighter bottles.
But a new study which was commissioned by the plastic bottle manufacturer Portavin shows that while the bottles might be better for the environment they are not so good for wine over the long haul. While wine stored in plastic or glass taste similar at first, after eight to 12 months the taste changes. The PET bottles let air in, oxidizing the wine.
The cheaper, lighter bottles should be used for more inexpensive wine which will be consumed quickly.
