I've read that if there is too much alcohol, then the bacteria are overwhelmed, but what the best proportion is, I don't know. I've used a couple splashes of live vinegar with a pint of wine and with a liter, and they both worked out okay. Other factors could be light exposure--light will kill the bacteria--and temperature--cold inhibits the fermentation. My vinegar jars live in the cabinets above the refrigerator, which are slightly warmer than the rest of the apartment.
