The vinegar experiment...part 1

A few months ago, I got it in my head that a great way to use leftover wine or wines Jon and I didn't really like was to make vinegar out of them. So I got Jon to get me a vinegar "mother" from his brew supply store, I bought a crock, and I began to add wine. Tried it a while ago and figured out that constantly feeding "mother" wasn't the best of plans as the vinegar wasn't fully maturing. I've left it for about a month now. The instructions say a month or two should do it. So, I'm crossing my fingers that my three gallons of vinegar will turn out OK. Anyone have suggestions for additions to bottles of red wine vinegar? Garlic is a no-go as unless you add enough citric acid it could grow botulism. I have no intention of poisoning anyone. :)
