Boil the water. Remove from heat and then mix the hot water and sugar into the glass jar.
Stir until the sugar dissolves. Place the tea bags into the jar and leave it to steep until the water cools completely.
Once the tea has cooled, remove the bags or strain all the loose leaf tea from the jar.
Add the cup of starter tea or vinegar.
Add your SCOBY to the mixture with your wooden spoon. You can also carefully use your hands so long as they're thoroughly clean.
Cover your jar with the cheesecloth and secure with a rubber band.
Let your mixture ferment for 7 - 10 days out of direct sunlight.
After the fermentation process, pour the kombucha out into a bottle with an airtight lid.
