It is enough to drink two glasses of Kombucha each day.
Best in the morning before eating.
If you like you may drink even more Kombucha, up to one liter each day.
For drinking two glasses each day you need at least a 2,5 liter glass to prepare the Kombucha.
Kombucha tastes best if it is cooled.
You can dilute the Kombucha with juice if you like.
If several people like to drink Kombucha regulary, it is needed, to cultivate several Kombuchas. That is quite easy because the Kombucha culture multiplies by itself after a while, so you get lots of Kombucha babies in a rather short time. You only need to get huge glasses for the cultivation.
