yes, we've almost finished the qt. ds likes it, but it's too sweet for me (I'm not used to sugar, even fruit sugar, I guess)...it's a tiny bit syrupy and the mango chunks are great (they taste like mango hooch

)
it didn't get fizzy at all and it was in the cabinet for two days and the fridge about 2 days, too, in just a glass qt jar with a screw on metal lid with the little rubberized area.
I have three gallons brewing right now

and I may have found someone IRL who wants a SCOBY!!
flavoring it was fun, but the mango expanded to about 1/3 of the jar so maybe I just got excited and put too much?
I don't know how to tell if it's "contaminated" for sure...I think it'll either smell so bad you won't drink it (b/c it's probably dangerous) or it'll taste "off" and you'll know that your balance of bacteria and yeast is out of whack
As far as the towel getting soaked, I use very clean prefolds (we used them as burp cloths ages ago) and I've had one get soaked. it didn't cause any problems
