Brown Ale Vinegar Boy did i mess up haha!

As I recall once back when i had Made a brown Ale I remembered i had a 5 gal batch fermenting, well work got busy some things came up in the family i had forgot about the batch. I happen to go out to the barn 3 weeks later to find that my beer had some how converted it's self in to vinegar. this was the look on my face. ha ha how did that happen? This has to this day been a mystery to me, did i create brown ale vinegar?

A bacteria called acetobacter causes alcohol to turn to vinegar. Somehow it got in there and did just that. I'm sure there are plenty of things you can do with it, aside from pouring it into a glass and drinking it!

Any fruit flies floating around? Their little feetsies are covered in acetobactor, they often turn wine into vinegar.
