Make your own green tea kombucha! Here's how: 

Ingredient list: 
1 scoby (symbiotic culture of bacteria and yeast) culture starter (and 1 cup of kombucha that it comes with)

*Please note, if the bacterial culture is not fermented properly or cooking equipment is not extremely clean, kombucha can spoil and be unsuitable for consumption.
