If you check on your scoby and see that it's turned black, then the scoby has died. The best practice is to throw it away and any batch of tea that was made using it. A dead scoby does not necessarily mean that you did something wrong. Remember, it's a living organism and has a lifespan.

How long does scoby last?

Once the SCOBYs are dehydrated, place them in a sealable plastic bag and store them in the refrigerator (not the freezer). Dehydrated SCOBYs will generally survive in the refrigerator for at least 3 months. Once you are ready to begin making kombucha again, follow our instructions on how to rehydrate the SCOBY.

How can you tell if your scoby is bad?

A SCOBY can have streaks of brown or black on it – this is just leftover remnants of tea from the last brew. You can tell if a SCOBY is moldy by the presence of mold. And mold does NOT look like leftover tea bits. A moldy SCOBY has white or gray fuzzy growths on it.
