Box wine

The original design required that the consumer cut the corner off the bladder, pour out the serving of wine, and then reseal it with a special peg.

[4] In 1967, Australian inventor Charles Malpas and Penfolds Wines patented a plastic, air-tight tap welded to a metallised bladder, making storage more convenient.

[11][12] During the mid-1970s, the bag-in-box packaging concept expanded to other beverages, including spring waters, orange juices, and wine coolers.

[14] This, coupled with an increased cultural interest in environmentally sustainable packaging, has cultivated growing popularity with affluent wine consumers.

[15] Box wines utilize plastic bags instead of traditional glass bottles, significantly reducing production and shipping costs, which makes them a more affordable option for consumers.

[19] Tyler Colman from The New York Times stated that bag-in-box is more environmentally friendly than bottled wine [15] as well as easier to transport and store.

The Australian wine industry has benefited from favorable tax policies, which have led to a substantial increase in both domestic consumption and international exports.
