Just found this bottle of kombucha that I put in the cupboard for second fermentation in the fall of 2019. Sadly the scoby will be sacrificed due to the small mouth of the bottle. Do you think I can use the liquid to birth a new scoby? Do you think it's vinegar? Is it safe to drink? I'm afraid to release the stopper. I'd be interested in comments or suggestions from experienced brewers. Thank you!
