I have a bottle of apple juice (from concentrate) in the back of my fridge that's half frozen. I'd say it's at least a few months old. I want to use it to make pulled pork over the weekend, do you think it's still okay? I would have tasted it before leaving the house this morning but as I said, it's half frozen. I just don't want to buy a whole new bottle of apple juice if I don't need to.
