Is starter tea just kombucha that has sit in a jar after first fermentation

Elysium82

Hi,
So, I have just learnt that I need to add 10% of starter tea to the freshly brewed tea to kickstart the fermentation. So, I already have a starter from a friend, but how do I make my own starter?
I just put some kombucha (that has gone through 1st fermentation) into a jar and leave it like that? Is that a starter I can use for my next batch? If yes, how long can I keep that in a jar at room temperature?
Thank you.

When I made kombucha many years ago I would just transfer a chunk of scoby from the old batch to the new one.
To start it the first time I bought a bottle of commercial kombucha at the grocery store. I looked through all the bottles to find one that had floaties and some scoby in it, then when I got home I opened it and left it covered on the countertop for a few days to grow the scoby more.
