Bring 12 cups of water to a boil.
Add sugar and dissolve.
Add yerba mate loose tea, or tea bags, to water and sugar mixture.
Turn off heat and let brew for at least 10-15 minutes. The longer you brew, the stronger the flavor.
Strain your tea, if necessary, into your brewing vessel. Let cool.
Once completely cool, add your kombucha starter liquid and SCOBY.
Cover with a thin cloth or a towel and rubber band to secure.
Let brew from 6-14 days. Houses warmer than 70 degrees will take less time than cooler houses.
When your kombucha is to your taste, you can drink right away or store in bottles* in the fridge.
Reserve 1 cup of starter liquid to use on your next brew.
