The materials and ingredients needed to make Kombucha are simple.
You need glass jars to make it in, tea (bags or loose leaf) sugar, and a Kombucha culture or Scoby
The choice/brand of tea is up to you and the type of sugar is also unimportant, as long as it gets an adequate amount. Sugar is vital for the fermentation process and for those wanting a low sugar drink, it's just a matter of fermenting it for sufficient time to bring the sugar level down very low.
Simple as that! Now for instructions on how to make Kombucha read the 'Making Kombucha' page
