Closure is a term used in the wine industry to refer to a stopper, the object used to seal a bottle and avoid harmful contact between the wine and oxygen.[1]
They include:
The choice of closure depends on issues such as the risk of cork taint, oxygen permeability and desired life of the wine.[2] Another factor is consumer reaction, with the wine-buying public in Australia and New Zealand positive to alternative closures, while opinion is divided among consumers of the United States.[3] In Europe, perceptions that associate screw caps with low-quality wine may be declining.[2]
