I recently started brewing kombucha and in one of my 7 day old jars I have a 1/4 inch scoby growing. I slid a straw down the edge to taste and then the scoby sank to bottom and is still sunk after a day. It's a bit too sweet. My last batch tasted just right at 9 days, but that batch was left undisturbed. I'm wondering if this current batch is slowed down now since the scoby isn't getting oxygen? So at 9 days it won't be like the previous batch?Will the drink still ferment with no growth on the top?
