I've been giving brewing my own kombucha a try, following this guide. It's been going well, and I've made it all the way through my first batch! \o/

The one bit where I differed from the guide was in the last fermentation, where I also add in the flavors: instead of using flip top fermentation bottles, I used mason jars. I did this because I didn't want the final bottles I'd drink from to have bits of fruit, etc., so I'd do the flavoring and final fermentation in the mason jar, and then strain the actual kombucha into individual bottles for drinking. By doing this, though, I think I lost a good bit of the carbonation from the last fermentation... which is not ideal.

Are there any ways to effectively rebottle kombucha without much loss in carbonation?

Absolutely. Add a maximum of 1/2 teaspoon of sugar per 12-ounce bottle, or 1 teaspoon per 22-ounce bomber, etc. Then allow another "final" fermentation within the sealed bottles for another week or two. After the first batch you can adjust the amounts of sugar to suit your desired level of carbonation. And you can also substitute honey or a greater amount of fruit juice, etc. In the end you're going to want to add some sugar from some source in order to keep fermentation in the bottles.

  • Trying my second batch now, and will attempt this technique. In the meantime, do you find that doing this impacts flavor at all?

  • Not that I can detect. Just the carbonation.
