Brew your own kombucha at home from one shelf stable pouch. Inside is a single dehydrated SCOBY, the symbiotic culture of bacteria and yeast that turns sweet black tea into tangy, lightly fizzy kombucha, along with five pH strips and a step by step instruction booklet.

Because the culture arrives dehydrated rather than alive in liquid, it waits quietly in the refrigerator until you are ready to begin, and once activated it can be kept going batch after batch. You supply the sugar, the plain black tea, distilled white vinegar and water. Net weight 0.08 oz (2.4 g).
