Cork is used in a variety of products, the most familiar of which is a wine stopper-or cork! The material's natural compressibility and near-impermeability make it ideal for this purpose, and natural cork is used for about 60% of wine stoppers today. Wine can become tainted during the process of bottling, ageing, storage and transport, and although other factors cause tainting, the stopper is usually held responsible. This association in the mind of the consumer is so strong that a bottle found on opening to have undesirable smells and tastes is usually said to have become 'corked'. The use of alternative wine closures has grown in an attempt to prevent cork taint. For example, the synthetic cork, designed to look and function like a natural cork, avoids the risk as it is made from a resin that does not contain trichloroanisole. However, alternative closures themselves bring their own disadvantages. Wine experts have noted that a synthetic cork can impart its own slight chemical flavour to wine, replacing one type of cork taint with another. Screw-top bottles provide an alternative free of the risk of cork taint, but present an entirely new problem: consumers associate a screw-top bottle with poor quality wine, regardless of its price, vintage or reputation.
