Bring water to a boil. Turn off the heat and steep tea bags 4-6 minutes. Discard tea bags.
Add brown sugar. Turn heat back on to low. Heat 1-2 minutes, until sugar is dissolved. Let cool.
Chai Kombucha
Line up 4 (25 ounce) bottles with flip top lids or other air tight bottles.
Pour ½ cup chai simple syrup into each 25 ounce bottle.
Using a funnel, pour freshly made homemade kombucha into each 25 ounce bottle leaving 1-2" head space.
Let bottles sit out (at 75° - 85°) 3-5 days, making sure to pop the lids each day to let out the pressure of the carbon dioxide. Taste each day to test its flavor and fizziness.
Refrigerate when you are happy with the amount of fizz and flavor.
Notes
Use freshly made homemade kombucha that has not been refrigerated yet.
