Why does my bread smell like vinegar?

I have some bread that should still be good for few days that now smells like vinegar. There is no mold, ect. on it that makes it look bad. It is store bought whole grain bread with some oatmeal, if that matters. Personally, I've never known bread to smell like vinegar, even when it has gone bad. So what would cause it?
