Screw cap (wine)

A screw cap is a metal, normally aluminium, cap that screws onto threads on the neck of a wine bottle, generally with a metal skirt down the neck to resemble the traditional wine capsule ("foil"). A layer of plastic (often PVDC), cork, rubber, or other soft material is used as wad to make a seal with the mouth of the bottle. Its use as an alternative to cork for sealing wine bottles is gaining increasing support. In markets such as Australia and New Zealand screw caps on bottles have overtaken cork to become the most common means of sealing bottles.
