How long does SCOBY keep at room temperature?

It is recommended that you do not place your SCOBY at room temperature for more than a week. 

A SCOBY can be held for one week between brews, although this is quite simple. Don’t forget to bring your SCOBY and some kombucha.

To keep the SCOBY hotel healthy. Place the SCOBYs in a liquid medium. You can use kombucha and sweet tea to feed SCOBYS for at least four to six weeks or so.

Can bacteria and mould growth be possible in Scoby?

Scoby can easily be stored in a refrigerator for up to 6 to 8 months depending on its condition.

The cold inhibits the fermentation of kombucha. Temperatures that allow SCOBYs to survive, stay healthy, and ferment is ideal. 

The temperature ranges from 65 degrees F (18 degrees C) to 85 degrees F. (29 degrees C). If your SCOBY is not used in a setting below 65 degrees Fahrenheit, it may become slow, inactive, or even die.

Is it safe to store Scoby at room temperature?

It is not necessary for cultured kombucha for Scoby to store in the refrigerator. Because they are shelf-stable. 

So it is good to store them at room temperature until or unless you are going to brew them. If you’re between batches, simply keep them in a jar with a cloth cover, just like you would for primary fermentation.

Is it possible for a SCOBY to grow old?

The SCOBY germs are replicating, but they are also ageing and dying off. The colony’s average age increases over time.
