A special packaging (Engl. "bag in a box") for beverages, invented in 1955 by William R. Scholle. It became popular in the 1970s and was mainly used for milk, fruit juices and later also wine. The liquid is contained in a bag made of film composite material (for example aluminium/polyethylene or polyethylene/ethyl vinyl alcohol), which is protected by a stabilising cover made of corrugated cardboard or wood. In addition to the classic bag-in-boxes with cuboid cardboard, there are also more visually sophisticated ones in cylindrical form (bag-in-tube). There is a pouring valve on the bag. When emptying, the bag contracts so that the leaking volume is not replaced by air and oxygen contact is avoided. This ensures longer flavour stability. The volume for wine containers is 1.5 / 3 / 5 and 10 litres. In the meantime, special, inexpensive cool boxes are also offered for this purpose, in which up to three BiB's can be accommodated. Power can be supplied via the normal mains supply, but also via a cigarette lighter in the car.
For my many years of work as an editor with a wine and culinary focus, I always like to inform myself about special questions at Wine lexicon. Spontaneous reading and following links often leads to exciting discoveries in the wide world of wine.Dr. Christa Hanten
