A: You can store Kombucha cultures in the refrigerator for a short period of time, roughly 2 weeks is all we recommend. Storing in the refrigerator is a risk - if Kombucha cultures are refrigerated, the yeasts and bacteria go dormant in the cold temperatures and can have a hard time bouncing back to full brewing strength after they have been chilled. Sleepy yeast and bacteria leaves your brew more at risk to develop mold.
If you do refrigerate your culture, store it in a glass jar in at least 1 to 2 cups of starter tea with a lid. The night before you would like to brew again, simply remove it from the refrigerator, place on your countertop and cover with a cotton cloth and rubber band. Allow the culture to return to room temperature over night before brewing the next day. If it has been refrigerated for a period longer than 2 weeks, use the process in the above answer to feed your culture the night before brewing with it.
