I once met the son of one of Chile's largest wine producers. He had recently set up his own wine export business. When he mentioned he was also selling cask wine (i.e. wine in a cardboard box with a plastic bladder), I assumed this was cheap, inexpensive wine. He told me that he sold some of his better wines this way because a lot of European hospitality businesses preferred it. Makes sense when you consider that it will keep much better than bottled wine once 'opened'.
