3 Ways to Boost Carbonation in Homebrew Kombucha

How do I add more carbonation in my home-brew kombucha? Read the YEABUCHA sisters tip for adding more carbonation to your home-brew.

“How can I get more bubbles in my kombucha?!” This is one of the most common questions we get from new brewers. Let’s be honest, nothing beats an ice cold glass of fizzy kombucha, making it the perfect healthy soda alternative. Sometimes you might find your home brew lacking carbonation, but after plenty of exploded bottles, we promise home brew can be just as carbonated as store bought kombucha-maybe even more! If you’re looking to increase the carbonation of your home brew kombucha, check out 3 ways to boost those bubbles: 


Adding more carbonation into your home brew kombucha yeabuchaFill and SealThe less air you leave in your second fermentation (F2) bottle, the better! So when bottling and flavoring, be sure to fill your bottle all the way to the top. Seal them tight and store in a dark closet with limited air flow for 2-4 days. Our bottles that come with the deluxe kit create a super tight seal which is perfect for locking in the carbonation (don't worry, we sell them separately if you want them!). *Fun fact, F2 is where most of the carbonation you enjoy is produced! As the yeast continues to break down any remaining sugar (plus sugars in the fruit), it produces the CO2 we love so much. Certain fruits naturally produce more carbonation than others, so try adding in ginger or strawberries to your next batch to see how it affects your carbonation. 

How to increase carbonation in your kombucha home brewLet it Warm UpYour brew might be a bit too chilly to get the results you’re looking for.  We aren't the ONLY ones who slow down when it’s cold, yeast does too!! Instead of taking a bottle of booch out of the fridge and opening it right up, let it sit on the counter for 5 - 8 minutes. Before opening, tip the bottle over one time so the sediment on the bottom starts to move, just don’t shake it.

In your brew jar, yeast tends to hang out at the bottom, while all that good bacteria stays closer to the top.  Instead of pulling 2 cups of starter liquid for your next batch from the top of the brew, take 1 cup from the top and 1 cup from the bottom.  This should only be done one or two consecutive times and then return to pulling starter liquid from the top to avoid throwing off the balance of your brew.

    I use airlocks on glass growler bottles like what is used in beer making during second fermentation. I keep at room temperature. Lots of bubbles and no exploding bottles.


    Hi Gayle, this suggestion is for small batch brewing. One of the reasons we prefer B.B. is because it allows a lot more control over final product as opposed to continuous brew. You might want to give small batch a try! With our kits and simple steps it’s really just a little bit of hands on time each week.

    You mentioned pulling a cup off the top and a cup off the bottom to start a new batch. I use 2 1/2 and 3 gallon jars with spigots, so when I pull off to bottle I run it out the spigot. I pour my new tea in the jar and so my starter is always what’s left on the bottom. What would you do with that kind of setup?
