The scoby pellicle on my kombucha is now fully across the jug, and there's a baby one from the second batch I just bottled. The kombucha fizzed a lot when I put it in the individual bottles with the flavors. It didn't do that last time. So, if I leave it sit to ferment and infuse with flavor a bit, I think the carbonation will actually happen this time. I'm not burping the bottles this time either.
