“Hi, I’m new to making Kombucha and I have a concern about bottling KT after the second ferment. I have read on many sites that there’s a chance the bottle can explode from carbonation buildup and that …I should be very careful. So how do I be very careful? Moreover, is that really a concern? I see on your site that you do not mention it when explaining how to bottle KT. Is that only a concern after the second ferment?”
Bottling is the best way to extend the shelf life of the kombucha beverage. There is a concern with excessive buildup of carbonation when bottling. Below are some steps to follow when doing the secondary fermentation:
1. Do NOT add extra sugar or juice when bottling. This adds raw sugar source which the yeasts will turn into carbonation & alcohol)
2. Use quality bottles such as Grolsch style beer bottle (Grolsch or standard beer bottles are designed to hold extra pressure)
3. Leave a 5% head space when filling each bottle and the pH is below 4.5
(In the beverage industry, this amount is required by the FDA)
4. Just to make sure all is safe, keep your bottles in a cardboard or plastic box to keep glass and liquid from going every where Following these easy steps will assist you in your secondary bottling process. Please comment below with any other questions or a tip you may have to share.
