History

The process for packaging 'cask wine' (box wine) was invented by Thomas Angove of Angove's, a winemaker from Renmark
Renmark, South Australia
Renmark is a town in South Australia's rural Riverland area, and is located 254 km northeast of Adelaide, on the banks of the River Murray. The Sturt Highway between Adelaide and Sydney runs through the town; Renmark is the last major town encountered in South Australia when driving this route. It...

Bag in a box packaging is also preferred by producers of less expensive wines because it is cheaper than glass bottles. A bag of wine, removed from the box, will float on water, allowing quick cooling of a white wine by immersion in an ice bath.

The packaging first found commercial success in the land of its invention Australia, and while it has since established a steady market across Europe and South Africa, in the US the boxed wine has found difficulty in overcoming a down-market image.

Pros and cons

Bag-in-box packaging has some advantages over bottles and is preferred by some wineries because it is far less expensive, lighter and more environmentally friendly than bottled wine and far easier to handle and transport. Boxed wine is typically cheaper than bottled varieties, often around A$10 (GBP£6, US$10) for 4 litres in Australia.

The primary benefit that bag-in-box packaging offers to consumers is that it prevents oxidation of the wine during dispensing. After opening, wine in a bottle
Bottle
A bottle is a rigid container with a neck that is narrower than the body and a "mouth". By contrast, a jar has a relatively large mouth or opening. Bottles are often made of glass, clay, plastic, aluminum or other impervious materials, and typically used to store liquids such as water, milk, soft...

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. Cask wine in Australia is colloquially referred to as "goon" which is a term derived from the word flagon

meaning a large vessel used for drink, or "boxy", in reference to its low price and high alcohol content. Goon is the shortened version.
Box wine has environmental benefits. The bag allows a content of 2–10 litres, so that far less packaging mass is required.
