A corked wine is a wine that has been bottled with a cork that is contaminated with TCA – Trichloroanisole. Sometimes the contamination comes from the barrel the wine was stored in.
In a corked bottle – wine will get worse as its exposed to the air. Cork taint is a set of very undesirable aroma and flavor characteristics that are imparted into the bottle.
You have three choices: tip it, drink it fast, or stick a zip lock bag inside the bottle. The zip lock will absorb some of the TCA; it wont fix the wine but it may be drinkable
