Taking a Break from Fermentation: How to Properly Store Your Kombucha SCOBY

Do you want to take a break from making your own kombucha or keep your SCOBYs as a backup? A so-called SCOBY Hotel can help you store your kombucha culture between fermentations. Here you will learn how to properly store and care for your SCOBY and prepare it for the next batch of kombucha.

What Is a SCOBY Hotel?

A SCOBY hotel is a clean glass container in which you store one or more kombucha SCOBYs with enough mature, unpasteurized kombucha as starter liquid. The acidic liquid creates conditions that can inhibit many unwanted microorganisms. However, it does not fully protect the culture from contamination or mold.

How long you can store a SCOBY depends on several factors, including the condition of the culture, the acidity, hygiene, and temperature. There is no fixed storage time. Check your SCOBY hotel regularly and discard the entire batch if you notice mold or other suspicious changes.

What Do I Need to Store a Kombucha SCOBY?

1. Mature, unpasteurized kombucha as starter liquid, with enough to keep the SCOBY fully submerged.
2. A clean glass container with a wide opening.
3. A clean, breathable cloth and a rubber band to cover the container when storing it at room temperature.
4. For cooler storage, a suitable, clean storage location. Keep in mind that cold temperatures slow down the activity of the culture and that it may need time to reactivate before the next batch.

What Should You Keep in Mind When Storing Your SCOBY?

Maintain Good Hygiene and Monitor the Culture

Before your SCOBY goes into storage, you should thoroughly clean the SCOBY hotel. Use a clean glass container and rinse off all soap completely. Vinegar can be helpful for certain cleaning tasks, but it is no substitute for thorough cleaning and disinfection when necessary. Also make sure your hands and utensils are clean when handling the SCOBY.

Brownish or dark yeast strands and deposits can form on the SCOBY. These are often normal during kombucha fermentation and do not necessarily need to be removed. The most important thing is to regularly check the culture for any noticeable changes.

Different Ways to Store a SCOBY

Storage at Room Temperature: Store the SCOBY in a clean glass container with enough mature kombucha and cover the opening with a breathable cloth. This allows air to reach the surface while keeping insects and contaminants out as much as possible. Fermentation can continue, and another layer of SCOBY may form over time.

Cooler Storage: Lower temperatures slow down the activity of the yeast and bacteria. Therefore, a SCOBY may take longer to become suitable for a new batch after being stored in a cool place. Cooler storage is not the same as long-term preservation. Do not use an airtight bottle for an active culture if pressure can build up inside.

New SCOBYs Form: When stored at room temperature, a new, thin layer of SCOBY may form on the surface of the starter liquid. This is a normal possible outcome of fermentation. Make sure the culture remains sufficiently covered with starter liquid and that the container is clean.

Properly Caring for and Thinning Out SCOBYs

Several layers of the culture can form in the SCOBY hotel. You do not need to trim or thin them out regularly: A thicker layer of SCOBY is not automatically a problem. If you want to remove older layers, work with thoroughly cleaned hands and clean utensils. Avoid unnecessary cutting and frequent handling to keep the culture as uncontaminated as possible.

Oxygen supply takes place mainly at the surface of the liquid. A breathable cloth allows for air exchange. Thinning out the SCOBY is not necessary to prevent generally harmful gases. What is important are a suitable starter, clean working practices, and regular monitoring of the culture.

Rotating SCOBYs in the Hotel

A SCOBY hotel can also be used to store cultures between different kombucha batches. You can take a SCOBY and some mature kombucha from the hotel to use for a new batch and store another culture there. This gives you a backup in case you want to replace a SCOBY.

Other kombucha brewers prefer to use the same culture repeatedly for their fermentation. Which method is right for you depends on your working methods and storage conditions. In any case, handle everything cleanly and only use cultures that look normal and smell pleasantly tart.

Frequently Asked Questions About SCOBY Storage

How Long Can a SCOBY Be Stored in a SCOBY Hotel?

This depends on the culture, the acidity, hygiene, and temperature. There is no fixed storage time that applies to all batches. Check the SCOBY regularly and make sure there is enough suitable starter liquid.

Does a SCOBY Need to Be Completely Covered with Kombucha?

The SCOBY should be sufficiently submerged in mature kombucha so that it does not dry out. A new culture may also form on the surface. Make sure the container remains clean and that the cover protects against insects and contaminants.

Can I Store a SCOBY in the Refrigerator?

Cool temperatures slow down the activity of the culture. Therefore, it may take longer for the SCOBY to reliably ferment a new batch after storage. Monitor the condition of the culture and carefully observe the new batch.

How Can I Tell if My SCOBY Should No Longer Be Used?

Fuzzy, dry patches or noticeable green, blue, or black discolorations may indicate mold. If you suspect this, you should discard the entire batch, including the SCOBY, and not taste it. Brownish yeast strands alone, on the other hand, are not automatically a sign of spoilage.
