If YOU were an acetobacter, could YOU live in all that spice? :-D. But seriously, as has been said before here, keep everything sterile and there's no reason for problems. Unless you pick a toting pumpkin to begin with. That would not be good.
Considering: Sparkling raspberry wine, carrot wine
In Primary: Ed's Apfelwein; Raspberry Puree Apple Cider
In Secondary: Pumpkin Pie Mead; Traditional Mead; Dried Elderberry Wine; Blueberry Wine; Texas Persimmon wine; White grape/peach wine; Texas Twang; Hi, Biscus! Metheglyn; A Maize-ing Wine
So far, so good.
