There are stories all over this forum of people dropping unsanitized bottles, bbq lighters, hair brushes, phones, all kinds of stuff into their brew. And a lot of them, in a panic, reach in elbow deep to retrieve the item. And most turned out just fine. Also, with a fruit juice, I'd imagine the alcohol to be pretty high, & what do Dr.s use to prevent infections? Alcohol carb/condition away and enjoy your experiment.
