Does the cork show that a wine is corked?

[TheEngineer]

I've read and been told by colleagues that if a wine is corked then I should bring it back to the wine store so that at least they will know about it. Not necessarily trying to get a refund this time (since the wine was not expensive), but just for knowledge.


Are there signs on the cork that the wine is corked. What does it look like, what would I look for?

The wine I opened tonight I thought would have issues the moment I put my corkscrew in. The cork turned with the corkscrew after just barely entering the cork.
