Carbonation in Your Kombucha - 3 Ways to Add More to Your Homebrew

“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.

Adding more carbonation into your home brew kombucha yeabuchaPull More Yeast in Your Starter Liquid - Yeast is responsible for breaking down sugar and producing CO2. 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.

  • Hi Mir,
    With the YEABUCHA Method, we recommend lining the bottom of glass bottles with various fruits and herbs. Pour your kombucha over the fruit place in a warm, dark closet for 2-5 days. Place your bottles in the fridge. When you are ready to drink it, use a cocktail strainer over your glass to strain the fermented fruit. Check out our online store for any of your brew tool needs, and our newly added Digital Brew Card & Community Membership for continued help on your brew journey.

  • Hi! Can yo I explain to me how I can add flavour/fruit at the F2 stage but strain before bottling?
    Can I do f1 as normal and in the same jar add fruit and leave for a couple days (I don’t know how many??) and strain then bottle?
    I prefer a clean no fruit finished product
    Thanks for your help!!

  • Can u can a kombucha? I’m only asking because I make it and I’m the only one who drinks it so if I could can it or preserve it in someway I could store it out of the fridge

  • Hi Rachel! Thanks for the comment, if you’re happy with your kombucha, that’s awesome! If you’re still looking for more carbonation, try a small batch brew and see how they compare!
