I would say no because it is fermented with sugar. Even though the sugar is used up in the fermentation process it then contains alcohol in it if it is real home brewed kombucha. I'm not sure about the boxed stuff you can buy at the store.
Melissa, do you think in p3 it would be ok or shall I wait until p4? Will it last that long in the fridge? I lost .2 yesterday, no gain but not worth it. Thanks for the reply.
