Kombucha is a fermented drink made with tea, sugar, and a starter colony of bacteria and yeast called a SCOBY.
The slightly fizzy, acidic beverage has been around for thousands of years. But a recent wave of interest in fermented foods and home food production means that kombucha's experiencing a bit of a resurgence.
