Never throw a batch out because of something like this. The first thing to do is add 1/4 tsp of k-meta to your batch and stir it gently in. If you wish to age further, add some k-meta solution to the airlock and recap it. Then you can age for a while more until you are ready to bottle. The wine may have gotten contaminated and may be bad, but chances are good that it is still alright. The k-meta addition will help kill any undesireables that got in the wine. I would still bottle it and give it a while and try it. If it is truly bad, you should easily be able to tell then.
