Bit of a rescue mission for me I am afraid!
I started a CB just before Christmas - it's just a small one - it came with two small mothers and I set it up with a mix of green and black tea. the first draw was lovely and it remained the same for a couple of weeks. Formed a lovely white creamy looking healthy Scooby on the top which is over 1cm thick ... but then it went very vinegary!
I tried starting again but the result is the same. Do I have too much Scooby now between the two that came with the kit and the new one, is that why they are turning sour very quickly (by day 4 there is no trace of sweetness). Should I make a hotel or throw out the original two mothers and just brew with the new Scooby(starting from scratch with a little of the vinegar and new tea and sugar?
