** Different teas provide for different flavors. When using tea bags, I would usually use 2 plain black tea bags, 1 green tea bag, and 2 Sadaf tea bags. For the past year I’ve been using the loose leaf tea blend from Kombucha Kamp. Be sure to avoid caffeine-free herbal teas (the SCOBY needs caffeine to grow) and flavored teas that contain essential oils.
