Vinegar

[Tartar Horde]

We use wine vinegar in a few dishes and for dressings etc and were looking at some in the local Asda, moaning (as you do) about the prices. Another shopper overheard us and commented that all you have to do is add some wine vinegar to a bottle of wine and the Vinegar will "inoculate" the wine "turning" it into vinegar.
I'm not sure if this will work though as I thought you had to "brew" vinegar. I thought I would run it past your bullshit detectors before I do some research online. I have access to a lot of fruit and being able to make wine vinegar from homebrew, SEEMS to be a good idea.
