Kombucha, the effervescent and tangy health drink made from fermenting sweetened tea, is my family’s favorite beverage. We drink about 2 gallons of the stuff per week. But what if you’re a lone wolf, daring to make kombucha on your own? Where are you supposed to get a good SCOBY? The most reputable online stores charge anywhere from $20-$35 per kombucha mother. YIKES! So, I thought I’d show you how to grow your own for about $3.50.
