Default Wine turning to vinagar

I have some "wine" left over from fermenting fruit for another purpose. I put this wine in bottles and put in the fridge. It tasted pretty good at first but now there is this vinegar taste developing in the bottles. How can I stop this?

PS had the same trouble w/some hard cider I made last year. Tasted great, but continued to ferment into vinegar.

If it's truly vinegar, that is aceterobacter contamination. If it's just "sour", that could be a pedio or lactobacillus contamination.

If there is ANY headspace in a wine vessel, that can allow enough oxygen to allow an infection to take hold. In my area, fruitflies are the biggest carrier of aceterobacteri.

Well had a few people over today and a number of us tasted it and it seemed not as bad as I first thought. I even drank a whole lot. Maybe it's just very "dry"?
