As. Craig says, save it. Once you have ethyl alcohol in the system oxygen is your enemy , , , , a half full bottle will be about as bad as an open top container so look for a variety of sizes. Another potion is a bag in box metalized wine container in which I would aim for zero air stored in a refrigerator and then in thirty days at first racking add it back for topping off.
In the last couple years have wound up running the primary low with some extra in the freezer and then filling the first racking with raw juice till an inch headspace.
Worst case learn the flavor, see if you like it back sweetened, try a pinch of tannin, freeze some and see how you like it with bitartrate precipitated. , , , , Good wine has lots of uses.
