There's really no arguing that it's ugly. And kind of alien-looking. And yeah, even downright gross. But dang it! Scobys make some delicious kombucha! If you want to save a few bucks on your 'booch habit, there's just no getting around it. You're going to need a scoby. You can beg a scoby from a kombucha-brewing friend, or you can order a fresh one online. But there's one more option: you can grow your own.
