Bag in Box

Bag in Box – Wine in a cardboard box, usually some liters.
Inside the cardboard box there is a synthetic bag which lets no whatsoever in, but does lets you take out the wine. This is possible through the use of a small tap.
Biggest benefit: The box is square, thus easy to place and pour.
Just like with a Tetra-type of package (like orange juice in a literpack) with Bag in Box the quality of the wine is perfectly kept.
Moreover: The greater the capacity, the better the preservability of the wine.
The image of Bag in Box is very cheap however, so it is mostly used for cheap wines.
This could change: the screw cap had the same image, but is now more accepted as full-fledged sealing of quality wine.
