Thisre is a new kombucha brewery in New York, on Long Island. On their instagram, you can view a lot of cool kombucha brewing insights. I’m addicted to watching.

Most important is to add enough acidic starter tea to get the pH low. I have a 1000 liter tank dedicated to starter. It’s usually about 2.9 to 3.1 pH. When I pitch, I use 20% starter which usually drops my new batch to around 3.7 pH.
You have to get the new batch to at least less than 4.2 pH.
Where’d you get your starter? Perhaps it’s a vinegar mother and doesn’t have the complexity of microbes to be kombucha.
I’ve fermented up to 88F. Heat speed things up but 2-3 days is very fast.
Looks good. Feed it with some tea and sugar. A pints worth. With 4 oz of sugar. Make sure the tea has cooled before adding. Then leave it alone for 2-3 weeks and repeat.
I grew a brewery from 8 oz of starter and a 1 oz pellicle. You don’t need much but some tea, sugar and patience.
Is there any pellicle formation?
What’s the present average temp of the room where it’s stored?
Do you have a Brix reading?
Kombucha is pretty resilient. You may have thrown it off balance. You might want to wait it out.
You didn’t understand.
If you have a job like being a bartender, or waiter, and there’s often half full bottles… then you have a source to make artisanal wine vinegars.
