A disposable keg (keg = small barrel) developed by Lightweight Containers BV for filling and storing all kinds of liquids. The system works according to the well-known "bag-in-ball principle" (bag in the ball). The cylinder/barrel-shaped container made of PET ( polyethylene terephthalate plastic) contains a special inner bag that holds the respective beverage. The material of the pouch is odourless and tasteless. The contents are transported to the outside by generating pressure in the area between the pouch and the outer shell without the propellant gas used coming into contact with the beverage. In addition, the inner pouch provides effective light protection or UV light. Further advantages are reduced transport and storage costs. The container was developed for cider, beer and sparkling wine because it is particularly suitable for carbonated drinks. Increasingly, it is now also being used for wine.
Serious sources on the internet are rare - and Wine lexicon from wein.plus is one such source. When researching for my articles, I regularly consult the wein.plus encyclopaedia. There I get reliable and detailed information.
