If I had the quantity available, I would drink a glass every day. I'm working up to that. Right now I get a glass every other day, with some pauses when I have run out.
When a baby SCOBY grows, it can go into its own jar, to double your capacity!
I just 'split' my SCOBY for the first time today. (I have done two batches, I think.) I actually had three. Two nice thick ones- the original mother, and a baby that had grown up- and a thin baby SCOBY. I put the baby in with the teenager. You CAN just leave them in together, and they will function as one.
If you leave them longer than three weeks, they WILL need additional sugar added to their jar. So I guess you would need a SCOBY sitter. Or at least a visitor.
