It’s a good idea to keep a few backup cultures in what we call a scoby hotel just in case a batch that you are brewing goes bad. There are a few reasons your batch can become contaminated, and here are a few examples:
Saving a backup komucha culture is a must to ensure the sustainability of your kombucha brewing:
Every time a batch of kombucha tea is made, a new kombucha culture (aka) mushroom grows! We recommend that you save the new cultures (aka) baby’s in a glass jar with about a cup of kombucha starter tea and 3 cups of distilled water, next cover the jar with a cloth and a rubber band, just as you would with your kombucha brew. If you at any time have any questions about kombucha give us a call or send us an email
Organic teas are grown in unstable environments and may contain contaminants.
Most organic sugars are unprocessed and contain small particulates that can ruin your brew.
Anti bacterial soaps
Residue from antibacterial soaps can be harmful to your kombucha since it is a beneficial bacteria. You can use anti-bacterial soaps but be sure to rinse out your vessel well. Make sure to rinse with hot water until squeaky clean.
Tap water, filtered, spring, Reverse Osmosis, etc…
When using anything other than distilled water contains chlorine and trace minerals which can cause mold.
Although you can use these ingredients there is always a small chance it will grow mold. A small chance but none the less a chance, about 5% of batches that are made with organic ingredients become contaminated. About 10% of kombucha brews made with filtered water grow green, white, or black mold. Almost all batches of Kombucha tea made with tap water go bad. Personally I like using organic tea and sugar.
Treat your scoby hotel as you would treat your kombucha brew. Be sure to keep your backup container in a room temperature environment and always away from sunlight. Check on them every few weeks to see that they are properly hydrated. It is important to make sure they don’t dry out. Over time the hotel will loose a bit of liquid due to evaporation. When this happens just add a little distilled water to the container. Keep your babies happy !
