I make my own kombucha. I started the pellicle from scratch using elderberries and it took a while for the SCOBY to eventually form. But worth it, my SCOBY produces a very fizzy drink.

I can add anything during the second fermentation, such as herbs, fruits, and other flavourings. As a supplement, I only drink about 30 ml a day due to the sugar content. Nice to see a kombucha post here. :)
