Once you've got this kit up and running, you're never going to want to buy bottled kombucha again. Made by the fermentation-loving folks at Craft a Brew, this box is filled with everything needed to transform simple tea into delicious kombucha. The best part's that the included SCOBY (an acronym for Symbiotic Culture Of Bacteria & Yeast) will stay active indefinitely, meaning you can use the same kit to ferment infinite batches of your own tea into probiotic-packed, fizzy goodnesss.
