TCA (2,4,6-trichloroanisole) is a chemical compound created when natural fungi come into contact with chlorides (specifically 2,4,6-trichlorophenol or TCP) which are found in bleach, other fungicides and pesticides.

As well as cork, TCA can attach to wood, cardboard and plastics – including the linings of screwcaps and glass closures.

TCA does not travel through cork. It can only be transferred to wine if it comes into direct contact with it.

You can sometimes improve a corked wine by pouring it into a jug lined with plastic food wrap for several minutes, as the polyethylene in the wrap attracts the TCA away from the wine.
