I posted this in another apple cider thread but it did not receive a response. I do not want to further hijack that thread by repeating it there, so am opening a new thread. I hope somebody can help me out here. How long will an opened glass jug of apple cider last in the refridgerator? I've got an open jug that has been in there a couple of weeks at least. I drink a little bit of it now and then. Should I be concerned about storing it too long after opening, and if so, then what specificaly should I be concerned about?
