Well, I'm still a bit hesitant to use this myself, but I used to use ACV and think I might start up again. Here is what I can tell you about the yeast though: Yeast normally ferments the sugar in the molasses and produces carbon dioxide and ethyl alcohol. This is basic high school biology and the reason why bread dough rises and beer and champagne are fizzy. Now, I don't know if the lactic acid from the AVC (which was produced through a different type of fermentation reaction also in your high school biology book) might effect this normal process or not. But if it didn't then the longer the mixture sits, the more "carbonated" and alcoholic it should become. Ethyl alcohol by the way is not the same type of alcohol found in many skin products (which is called Iso-propyl alcohol, Isopropanol, or IPA) and I assume that it must not be as drying to the skin since no one has complained about that!
Also, this type of yeast is not the same as Candidia!
