Cork taint is a broad term referring to a wine fault characterized by a set of undesirable smells or tastes found in a bottle of wine, especially spoilage that can only be detected after bottling, aging and opening. Though modern studies have shown that other factors can also be responsible for taint – including wooden barrels, storage conditions and the transport of corks and wine – the cork stopper is normally considered to be responsible, and a wine found to be tainted on opening is said to be "corked" or "corky". Cork taint can affect wines irrespective of price and quality level.
The chief cause of cork taint is the presence of 2,4,6-trichloroanisole (TCA), and/or 2,4,6-tribromoanisole (TBA), in the wine, which in many cases will have been transferred from the cork, but which also can have been transferred through the cork rather than from it. Corked wine containing TCA has a characteristic odor, variously described as resembling a moldy newspaper, wet dog, damp cloth, or damp basement. In almost all cases of corked wine the wine's native aromas are reduced significantly, and a very tainted wine is quite unpalatable, although harmless. While the human threshold for detecting TCA is measured in the single-digit parts per trillion, this can vary by several orders of magnitude depending on an individual's sensitivity. Detection is also complicated by the olfactory system's particularly quick habituation to TCA, making the smell less obvious on each subsequent sniff.

Famous quotes containing the words cork and/or taint:
“When Prince William [later King William IV] was at Cork in 1787, an old officer ... dined with him, and happened to say he had been forty years in the service. The Prince with a sneer asked what he had learnt in those forty years. The old gentleman justly offended, said, “Sir, I have learnt, when I am no longer fit to fight, to make as good a retreat as I can” —and walked out of the room.”
—Horace Walpole (1717–1797)
“While I believe that with a fair election in the South, our electoral vote would reach two hundred, and that we should have a large popular majority, I am yet anxious, as you are, that in the canvassing of results there should be no taint of dishonesty.”
—Rutherford Birchard Hayes (1822–1893)
