A corky (or “corked”) wine has a bad smell and tastes of musty or moldy cork. It smells like a mildewed cloth that has been allowed to sit without drying. The cause of a corked wine is a compound called TCA (tri-color-anisole, which is produced by mold growth on the corks during aging and processing at the factory). There is no known way to fix a corked wine or recover the original flavour. If you come across a corky wine, throw it away and open another, especially if you’re at a restaurant. The restaurant should replace your wine for free. Wineries almost always replace corked wines free on the word of the restaurateur. If it is your own private bottle contact the winery.
