In this brief article, we will answer the question, “How long can a scoby live in the fridge?” and methods to store scoby.

How long can a scoby live in the fridge?

Scoby can live in the fridge for 1-2 days. It is never recommended to keep scoby beyond that duration in the fridge or even in the freezer. Kombucha does not go bad because of which it is not required to keep them in the fridge.

Instead, place the scoby at room temperature and in a cool and dark place. Scoby is not recommended to be kept in the fridge for a long time because there is a risk of mold developing in the kombucha after the kombucha is removed from the fridge. It is difficult to ferment them too.

When stored in the fridge, the cultures can go dormant as well. If you have kept a few batches of kombucha in the fridge for a short while, it is fine but does not keep them for a long time.

How to store scoby?

Prepare a new batch of kombucha

  • An ideal way of storing the scoby would be to prepare a new batch of kombucha. For this purpose, boil about 3 ½ liters of water on the stove and add 8 green tea bags. After the water boils, remove it from the heat source and allow it to cool for a while.
  • Add a cup of cane sugar to the tea and dissolve it. You can add the sugar into the tea immediately after you have removed the tea from the heat source.
  • Place the tea into a glass jar. Cover the tea with a lid and keep it for 2-3 hours. After 2-3 hours, pour the tea, into another glass jar. Place the scoby in this glass jar and close the jar with a lid.
  • You can also tie a cloth on the top of the jar before closing it.
  • Store the kombucha in a dark place and away from light. It can be kept at room temperature for 30 days and the process of fermentation would start.

Place it in a clean airtight container

Placing the scoby in a clean airtight container or a plastic bag is also a better way of storing scoby. Place one scoby per container or bag.

Fill the jar with ¼ of kombucha. You can also add some tea or sugar to the container. The amount of kombucha being stored does not have to be necessarily precise but remember that the scoby should have enough food to remain healthy.

You can place the scoby in the fridge for a short while. Remember that the fridge would make the scoby dormant. If you have placed kombucha in a bag, keep it in a dry place on the fridge. Avoid keeping the scoby for more than 3 months in the fridge.

Storing entire batches of scoby in one jar

Select a large glass container to place the scoby. Wash the glass container thoroughly prior to using it. Put your entire batch of scoby into the jar. Over a period of time, you can add more scoby into the jar. 

This way you have many scobys to use to prepare new baches.

Pour three cups of recently brewed tea and a single cup of kombucha onto the scoby. Add some green or black tea mixture into the scoby. You can prepare the tea by boiling the water and steeping tea bags in them for a while post which you can add cane sugar to it.

Cover the jar with a lid and keep it in a cool and dry place. The kombucha should be replaced in the container within 2 weeks. This is because there are more scobys added to the container which can quicken the fermentation process.

Can you dehydrate scoby?

No, never dehydrate scoby. When the scoby is dehydrated, it cannot function well. Even after rehydrating it, there would be no use. Also, there is a probability that mold formation can occur. 

The bacteria will also not reproduce properly which can disrupt the fermentation process. The bacteria and yeast require a proper environment to thrive.

How much kombucha scoby needs to be kept?

If you have 3 liters of kombucha, you would require 2 cups or 500 ml of starter culture. The quantity of scoby that needs to be used would vary depending on your recipe. You can use many scobys as well to prevent mold formation.
