Thanks for the response, Gens!
Actually, this was at about 2 weeks of brewing. I think it worked really fast because it was like 90 degrees here when I brewed it.
But yeah, i sort of thought it was because I was growing my first SCOBY.
My new batch (1 gallon made with that first baby scoby) is only 5 days old and there's already a new scoby formed, and when I tested it with my PH paper it was around 3 or 4. It tasted pretty good, so I think maybe it's done...
I guess I should probably buy a flavorless bottle to taste so I have a better idea of what I'm shooting for.
Anyway, thanks again!
