But boxed wine may have an environmental dark side: Some of the plastic bags inside the boxes contain Bisphenol-A (BPA), a synthetic chemical that has been in use for four decades to strengthen plastic food containers and other items but recently has been linked to a range of human health problems.

Why is boxed wine so bad?

The bottling process is bad for the environment, and a lot of glass is wasted during production as well. Once it’s open, you have a certain amount of time to drink it. Bottled wine is usually its best when finished soon after opening. It’s not advisable to keep bottled wine in the fridge for over 3-4 days.

Is boxed wine really that bad?

Boxed wine can be just as good as wine that comes out of a bottle, and there are many factors to consider before determining a wine’s worth based on appearances. Both boxed wine and bottled wine have the potential to be of poor quality or of great quality.

Box wines are lighter to carry than glass bottles, making them perfect for a picnic. They’re compact and easy to fit in the fridge. The airtight seal around the tap means less oxygen gets into the wine so some bag in box wines claim to last as long as six weeks, once opened (we recommend 3 to 4).
