pouches, relatively recent form of wine packaging made from polyethylene and aluminium. They have the advantage of being light (much lighter than a box, for example) and convenient, especially for smaller servings, but the disadvantage that wine stays fresh in a pouch for only a few months. Plastic taps ensure that wine in an opened pouch keeps reasonably fresh for three or four weeks. Relatively high sulfur additions are needed, however.
