So, we have already talked about how a cork can be inconvenient, but there are other negatives to a cork.

A cork can actually taint a wine and make it taste bad. 3-7% of corks are contaminated with TCA (2,4,6-Trichloroanisole). This TCA causes problems with the wine. People are able to detect this contamination in their wine, but many are unable to smell or taste it.

If the wine has a high amount of TCA in it, the wine can taste and smell musty. The TCA cannot harm you, however I am already broke and that $10 that I just spent on that bottle equals a lot of Ramen noodles and a bottle of shampoo. I need that.

If you get a corked wine, it is recommended that it be returned while it is full or nearly full. This way they are more understanding and willing for the exchange.

A corked wine is one of four common defects in wine.
