This instructable shows you how to grow a SCOBY (Symbiotic Culture Of Bacteria and Yeast) so you can continue brewing your own kombucha at home and not need to keep buying cultures. Your SCOBY will continue to produce new baby scobies every time you brew.

Step 1: Materials

When you brew kombucha, the SCOBY you started with will produce new Scobies. When you go to bottle your kombucha, this is the time when you separate the baby Scobies from the "mother".

If you look carefully at the picture above, you can see a smaller disc growing at the tea-line, just above the bigger SCOBY.

Step 3: Rehome

Move the baby SCOBY to its own container with some plain kombucha. Cover with a cloth or other type of lid. You can either set your baby SCOBY aside to grow at room temperature, or slow down the process by keeping it in the fridge. Ultimately, the SCOBY will grow to the size of its container.

Step 4: Feed

To keep your SCOBY happy and growing, add a cup of freshly brewed sugar tea every week or so.

Years ago a friend gave me a baby from her SCOBY. There were all sorts of rules for what kind of container to grown it in and what kind of utensils were allowed when you stirred it or strained it to prevent contamination. I would like to start one again but I don't remember all of it. Can you post more details?

I have read you should not use a metallic spoon. We use GIR silicon spoons. As far as containers, glass jars are great for brewing Kambucha. Store your SCOBY in any kind of Tupperware with some starter tea from the previous batch.

If it grows mold or doesn't look or smell right toss it. Better safe than sorry. check out r/findascoby to find people looking to rehome a baby.

Mine smelled vinegar-ish. What should it smell like?

vinegar is good. It shouldn't smell bad.
