The Fermented Mumma will discuss the process and benefits of fermentation, the problems with pre-packaged kombucha, and the endless flavour combinations for your custom booch. She will introduce you to a scoby (which stands for ‘symbiotic culture of bacteria and yeast’), the low-pH ‘mother’ from which your kombucha will spring. First, black tea and sugar are brewed together to make the starter tea. This is then poured over the scoby, covered in a cheesecloth, and left to ferment. The yeast consumes the sugar, excreting alcohol, which is processed by the bacteria into vinegar, providing a natural carbonation and tangy zing. New scoby babies form in the process.
