Wine can turn even when the bottle has never been opened. It is called Corked. They probably got a bad case of wine.
The bartenders were very nice but need better training with wines. On four different occasions I was served wine that had been opened a few days before and had turned. As I paid between 9 and 15 a glass for these wines, there was no excuse for this. They were always replaced with a glass from a fresh bottle but this should not have occured.
