Removing cork-taint from wine

The use of polyethylene, in the form of food-grade cling-film to remove trichloroanisole (TCA) cork taint from wine became a fad in the past year, capped by the release of a French-produced kit called Dream Taste, according to Huon Hooke in the Sydney Morning Herald.

The inventors claim their kit, which consists of a decanter and a bunch of grapes, will removee the TCA which, they say, affects 5 to 10 per cent of cork-sealed bottled wine. The grapes take about an hour to filter out the TCA.

The Australian Wine Research Institute has publised a paper on the removal of TCA using polyethylene. A researcher on the project claims that whilst the polyethylend removes the TCA it also removes other constituents and dulls the wine. However, a dull wine is arguably better than a cork-tainted wine!
