Plain black tea will give the best results, start with English Breakfast, Ceylon or Darjeeling. If you want to try some other options Oolong tea will also work and give a more fruity flavour. Green tea can be used but will produce a weaker ferment. To help with this add 500 mL of starter culture and two scoby’s.
We recommend completing at least 4 good batches to get a good strong culture before experimenting with teas.
