Can Kombucha tea be stored, and if so how long for?
A When your Kombucha tea is ready it is important to bottle and store it immediately in a cold place to slow the fermentation right down. The refrigerator is ideal, because its temperature virtually stops the fermentation process, thereby preventing the tea from going sour. If you only have enough room for one bottle of Kombucha at a time in the refrigerator, then store the rest in as cool a place as possible, such as a garage or outbuilding. In a warm room, fermentation will continue slowly and gradually turn the Kombucha sour and vinegary. Beware of commercial Kombucha beverage that is displayed out of a refrigerator, as it will probably be sour if it has been there for a week or two.
