Does wine left in the fridge more than the recommended time of up to a week (?) before it goes "off" go bad in terms of bacterial or mold overgrowth? Or is it safe to drink but just doesn't taste as good? I don't know if wine is as acidic as vinegar. And how long is really too long food safety-wise? I would probably just cook with it. I don't mind if it's vinegary, just asking from a food safety perspective. I hope this question is not too much like this one. Can wine gone bad be bad for you?
