Beyond that, I don't do anything. I'm certainly not sophisticated enough to be able to determine if a wine has been corked simply by smelling the cork, even if such a thing were possible, which many (including the article) suggest is not.
The sommelier at our wine bar actually brought out a bottle that we'd selected, uncorked it, he smelled the cork and said the wine was corked. He actually took the time to explain how to test it as well, and let us taste the wine so we'd know the difference, before bringing the fresh bottle.
The cork smelled a little rank and musty. I.e. like wine with a hint of gym sock. The wine itself just tasted "off". And obviously completely different than the fresh bottle.
What was interesting is that the corked bottle didn't taste terrible. It didn't taste *good*, but I'm sure my wife and I would have just thought it was a wine we didn't like, not actively thought the bottle was ruined by being corked, if we hadn't learned what corked wine smells and tastes like.
So now, I smell the cork when I open a bottle of wine.
We've only run into one instance since while out at a restaurant, and that was a wine my wife ordered by the glass. She got it, tasted it, said this isn't right. Had me taste it, and I agreed. They poured her a glass from a new bottle of the same wine and all was well.
