Flavor: add your desired flavors to each bottle, then funnel kombucha into bottles, leaving about 1 inch at the top. seal each shut.
Ferment: let ferment somewhere dark and room temperature for 3 to 10 days.
This process will go faster if it is warm in your house. carefully open bottles to prevent volcanoes. you can do this over a bowl with a baggie over the top just in case!
Serve: if desired, strain out flavorings before serving. place bottles in the fridge to slow the carbonation process and to chill before serving.
