Does the cork show that a wine is corked?

[wondersofwine]

A bottle of wine can also have a cork that has dried out and will crumble when you try to extract it (happened to me with a 1995 Oregon Pinot Noir recently). If the cork has allowed for leaks, the wine may be oxidized and prematurely over-the-hill. This is a different flaw from the TCA taint.
