How to Activate a Kombucha Scoby
Our kombucha scobys are sold in a dehydrated state, which preserves the yeast and bacteria present in the culture while greatly reducing the chance of spoilage. We value the safety of our customers! Our kombucha scobys can be activated for use through the following rehydration process.
When viewing this video, please note that any vinegar used in the rehydration solution should be at least 5% acidity, and should not be raw. A raw vinegar has its own bacteria and may compromise the kombucha culture.
Also please note that it is common for a new culture (baby) to NOT form in the rehydration batch, or even in the first couple of batches. You can successfully use the original culture to make additional batches of kombucha.

Activating the Scoby
Do not disturb. It is important to allow the kombucha to ferment undisturbed. Moving the jar or otherwise disturbing the contents will not ruin the batch but does make it more difficult to observe the most common signs the process is proceeding normally.
Signs the Rehydration Process is Complete
Allow the scoby to rehydrate for 30 days. You can halt the process prior to 30 days if a new baby scoby forms on the top of the liquid.
A new scoby may or may not form on the surface of the liquid during the rehydration process. While development of a new Scoby does indicate the rehydration process is complete, lack of a new Scoby development does not indicate the process failed (see below). A new scoby will start out as a cloudy haze or film developing on the surface of the liquid. If left undisturbed, the haze will become less opaque and more white in color and will thicken over time. If the original scoby is floating in the liquid, a newly developing scoby may attach to the original scoby making it more difficult to identify whether a new scoby has developed.
Please note, development of a new scoby is not required for successful rehydration. If 30 days pass and a new baby scoby does not develop on the surface of the liquid, use the following criteria to determine whether rehydration has been successful:
If 30 days have passed and the signs above are present, it is likely the process has been completed successfully and the rehydrated scoby can be used to make a batch of kombucha. Be sure to retain the liquid used to rehydrate the scoby to use as starter tea for your first batch of kombucha. If you have more liquid from rehydrating the scoby than you need to make your next batch, you can drink it. Click here to view our comprehensive instructions and how-to video for making kombucha.

Signs of Problems During Rehydration
While problems during rehydration are relatively uncommon, it is important to keep an eye out for these few signs that the process isn’t proceeding normally.
30 days pass with no signs of proper rehydration (see above). Click here for additional troubleshooting information. In a small number of cases, live cultures fail for unknown reasons. After reviewing the troubleshooting link, contact Customer Service for additional information to determine whether the culture is inactive and whether a replacement is needed.
Mold. If you are using appropriate varieties of water, tea, and sugar and adding the acidic component (starter tea or vinegar), the acidic nature of the brew makes it very uncommon for mold to develop. In fact, the most common cause of mold is forgetting an ingredient or using improper ingredient ratios that alter the acidic level of the brew. However unlikely, mold can and does occasionally develop and can generally be seen by the formation of white, green, orange, red, or black spots on the scoby or the surface of the liquid. If mold does develop, immediately toss the entire batch including the scoby. Do not try to salvage a moldy batch or a moldy scoby. Doing so may be dangerous to your health. Contact Customer Service for additional assistance.
Pests. The kombucha mixture is very attractive to ants and fruit flies which is why we recommend using a tight-weave cover and securing the cover with a tight rubber band to keep the invaders out. If you find worms (maggots) have infested your batch, this is a sign that fruit flies or house flies have invaded and laid their eggs. If this happens, immediately toss the entire batch including the scoby. Do not try to salvage an infested batch or an infested scoby. Doing so may be dangerous to your health. Contact Customer Service for further assistance.
Once your kombucha scoby has finished rehydrating it is time to use it to make your first batch of kombucha tea. Be sure to retain the liquid used to rehydrate the scoby to use as starter tea for your first batch of kombucha. If you have more liquid from rehydrating the scoby than you need to make your next batch, you can drink it. Click here to view our comprehensive instructions and how-to video for making kombucha.
