Corked wine happens at the winery. It's caused by a fungus that gets into the bottle before bottling and causes a taste in the wine reminiscent of wet cardboard.
You may be thinking of oxidation, which happens when wine is poorly stored and the cork dries out, allowing air in. Oxidation turns the wine to vinegar.
Or am I missing something?
