While cask wine may have a poor reputation, the packaging method does have its benefits. Bag in a box packaging is not necessarily inferior, but is simply preferred by producers of more economical wines because it is inexpensive. Cask wine is typically cheaper than bottled varieties, often around AU$10 (GBP£4, US$8) for 4 L in Australia.

The bag is not hermetically sealed and has an unopened shelf life shorter than bottled wine. Most casks will have a best-before date stamped. As a result, it is not intended for box wine

Wine cellar

A wine cellar is a storage room for wine in bottles or barrels, or more rarely in carboys, amphorae or plastic containers. In an active wine cellar, important factors such as temperature and humidity are maintained by a climate control system....
 and should be consumed within the prescribed period. Deterioration may be quite noticeable by 12 months after filling.

Manufacturers of 'higher class' bottled wines have complained about the cheapness of 'cask' wines, arguing that they provide a cheap means for alcoholics to become inebriated. In particular, the lower level of alcohol excise levied on cask wine in Australia (compared to beer and bottled wine) has been criticised as encouraging binge drinking.

Box wine is considered to have benefits from an environment protection point of view. The bag allows a contents of 5-10l, so that far less packaging or labelling is required. The material it is made from is very light, which reduces pollution caused by transport (as opposed to glass containers, which weigh much more).
