A kombucha culture is sometimes called a SCOBY (Symbiotic Colony Of Bacteria and Yeast). To start brewing, you will need a SCOBY to get you going. Once you have one, you’ll be able to brew kombucha forever - with each brew, a new SCOBY will form! Some cultures are trained to feed on different sweeteners. Most SCOBYs are fed by pure white cane sugar. We call SCOBYs that are trained to honey "jun."
