Could I just leave an old bottle of not-so-great wine out for awhile? If so, how long?

Editor: Amanda, we actually have instructions here for making your own vinegar from wine:
You will need a mother of vinegar to get the process started, as well as the wine. Without the mother (acetic acid bacteria) you will just end up with sour wine. You can get a mother of vinegar from some bottles of vinegar at the store, or directly from a wine-making supply shop.
Readers, have you ever made your own vinegar? Any suggestions or tips for Amanda?
