How to Grow a Kombucha Mother (SCOBY)

(With a Sprinkle of Love from me)

What’s a SCOBY, anyway?
SCOBY stands for Symbiotic Culture of Bacteria and Yeast. It’s like the queen bee of your fermentation hive! The Mother! Picture a jellyfish crossed with a science project—she might look a little quirky, but she’s the secret to transforming sweet tea into tangy, bubbly kombucha gold.

A SCOBY is both the architect and the byproduct of the fermentation process. This magical living organism feeds on sugar and tea, producing a fizzy, gut-friendly drink that’s as fun to make as it is to sip.

Here is my Step-by-Step Guide to Growing Your SCOBY (Mother)

Step 1: Gather Your Ingredients and Tools
Before we dive in, let’s make sure you’ve got everything you need:

  • Sweet tea: 4 cups boiled water, 1/4 cup sugar, and 1 tea bag (black or green tea works great).
  • Store-bought kombucha: Raw, and full of live cultures. (look for little pieces at the bottom of the bottle)
  • A glass jar: 1-quart size is perfect—clean and non-metallic.
  • A breathable cover: Coffee filters, cheesecloth, or a clean dish towel with a rubber band.
  • Patience: Good things come to those who ferment!

Step 2: Brew Sweet Tea
Bring 4 cups of water to a boil, then stir in the sugar until dissolved. Add your tea bag, steep for 5-7 minutes, and remove it. Let the tea cool completely to room temperature—your SCOBY prefers her tea lukewarm, not scorching!

Step 3: Combine Tea and Kombucha
Pour the cooled tea into your glass jar. Add 1/2 cup of store-bought kombucha. This is the jumpstart your SCOBY needs, like giving her the keys to her fermentation kingdom.

Step 4: Cover and Wait
Place the breathable cover over your jar and secure it with a rubber band. This keeps out curious fruit flies and dust but allows air to flow—SCOBYs need to breathe!

Set the jar in a warm, quiet spot away from direct sunlight. The ideal temperature is 75-85°F (24-29°C).

Step 5: Watch the Magic Unfold
Within a few days, you’ll notice a thin, gelatinous layer forming on the surface. This is your SCOBY-in-training! Over the next 1-4 weeks, it’ll thicken into a healthy, opaque kombucha mother.

Pro Tip from Felecia: Don’t poke the SCOBY—it’s not pudding! Give her space to grow without interference.

Step 6: Taste Test the Liquid
After 2-4 weeks, your SCOBY should be about 1/4-inch thick and raring to go. Take a sip of the liquid—it should taste tangy, slightly sweet, and fizzy. If so, congrats! You’ve just grown a SCOBY, handmade by you and nature.

Bonus SCOBY Care Tips

  1. Treat Her Like Royalty: SCOBYs thrive in the right environment. If your home is on the cooler side, consider a heating pad or tucking her into a warm cabinet.
  2. No Metal Allowed: Metal can mess with her vibe, so stick to glass, wood, or plastic tools.
  3. Feed and Rest: If you’re not ready to brew right away, store your SCOBY in a SCOBY hotel—basically a jar of kombucha in the fridge—and she’ll stay happy and ready.

Now that you’ve got your SCOBY, what’s next? The sky’s the limit! Brew endless batches of kombucha, share SCOBY “babies” with friends, or even start a SCOBY hotel for your next batch.

Growing a SCOBY is like adopting a funky new friend. She doesn’t need walks or belly rubs, but she’ll thank you with endless kombucha and a whole lot of fun. Cheers to your kombucha journey with Branch and Vines - Fermenting with Felecia!
