Kombucha is a type of tea fermented with cane sugar to produce a deliciously carbonated, slightly vinegary beverage that is full of probiotics. Brew Dr. raw kombucha is made with a base of brewed organic loose-leaf tea and high quality botanicals using traditional techniques. Each batch is naturally fermented for up to six weeks. The different flavors come from the different teas, herbs, and other botanicals that are added during the steeping process and the organic juices and purees that are added post-fermentation. Brew Dr is made using certified organic ingredients and without compromise on quality. Each bottle contains kombucha that is raw, real, and refreshing.
