Helloo, atm I'm making my first batch of kombucha, but soon my SCOBY (Symbiotic Cultures of Bacteria and Yeast) will be doubled so if anyone is interested in making their own kombucha, let me know! Then you can get a baby scoby from me :) Btw kombucha is "fermented, lightly effervescent, sweetened black or green tea drink commonly consumed for its supposed health benefits" (wikipedia).
Here is a website with more info on the process: https://www.goodhousekeeping.com/food-recipes/healthy/a20706158/how-to-make-kombucha/
if you want a baby scoby, write me an email: e.i.land@students.uu.nl
