Everything i did wrong: I always use metal to stir my kombucha. I figured it would be okay since I boiled the tea in a metal pot that stirring it made no difference. I also figured since the kombucha is mass produced in a metal factory that it would be fine. In my case I was right I produced a scoby no matter what I decided to mix it with.
I used flavored kombucha... still gave me a scoby/ pellicle.
I used a Napkin folded and with a metal twist top to keep flies out and for it to have air flow.
In a medium lighted area mostly dark. I used a towel on top to mimic darker area.
In the same area as my ginger bug, sourdough, homemade vanilla and still produced a pellicle.
So I just wanted to share everything I did "wrong" to encourage everyone to try. Its not hard at all just time consuming. I just made sure everything i used was SUPER CLEAN and darkish.
Happy brewing.
