Today was the day to refresh the Kombucha and the Jun. Both are fermented teas. The Kombucha is black tea sweetened with castor sugar which the SCOBY ferments creating a healthy, slightly effervescent drink with probiotics. The Jun is similar, using green tea rather than black and honey rather than sugar. I believe that the SCOBY (symbiotic culture of bacteria and yeasts) is also composed of slightly different varieties and the two do not seem to be interchangeable – when I tried to use a Kombucha SCOBY with tea sweetened with honey it grew mold.
