Why does kombucha contain sugar?


Sugar is what feeds the scoby. Often the kombucha mother doesn't eat up all the sugar leaving some residual sugar behind. The Good Guys kombucha has less than 5 g of sugar / 100ml while fruit juices and sodas often have 10 - 20 g of sugar / 100ml. In kombucha sugar is not added as a sweetener but for start the fermentation which results in healthy end products, such as organic acids and good bacteria.
