corked wine?

[elect]

In the past few weeks I have had 2 bottles that I opened smell like really bad BO. Is this the sent of of a corked bottle?

I did not notice the sent at first, as I had the wines stored in a wine fridge, but when the warmed up to room tempature (only a couple of minutes) the scent was overwhelming. I tried pouring the wine into another glass thinking the glass could be dirty but it didnt matter.

I wasnt sure if it was just bad luck to get 2 bottles in such a short period of time or if something else could be going on.

Thanks
