Step 1

Boil the 2 cups of water and steep the tea bags or loose tea for around 10 minutes. Stir in the sugar until it dissolves. Allow the tea to cool to room temperature.

Step 2

In your glass jar, mix the cooled tea with the 1 cup of store-bought kombucha.

Step 3

Place a cloth or coffee filter over the top of the jar and secure it with a rubber band or string.

Step 4

Put the jar in a warm, dark area where it won't be disturbed for 1 to 4 weeks until you see a 1/2-inch thick SCOBY form on the surface of the liquid. Check every week to see how it's going.

Step 5

With clean hands, remove the SCOBY from the liquid and start your first batch of kombucha.
