Long long time ago I had a few months where I brewed my own kombucha. At the time I was able to get a SCOBY by adding the bottom of a commerical kombucha to some sweetened tea which eventually grew into a full SCOBY which I used and split to make some batches. It was simple and easy

Is this something I can still do? Is there any brands that are more "raw" that would be a better starter?
