Bubbly Kombucha

Kombucha on any given day at my house.

Nothing is more important to me than having my kombucha be bubbly. When it is not.. well it hurts my feelings. Seriously it does. I need the fizz. It’s important to me. It also means that I have not given these microbes enough food to do their job. I have to do my part so they can do a good job for me. We are a team whether I can see them or not. They are there working their hardest for me. It’s my job to give them what they need and they will do the rest.

 

 

Let me explain to you how it all works. When making kombucha, the tea will form a scoby on top and it will be the size of the opening of your jar. It will  form a seal and this will let the yeasts in kombucha seal in the naturally occurring carbonation. Then the yeast will begin to consume the sugars in the tea and the by-product of this is a natural carbonation. Just as yeast makes bread rise, the good yeast in kombucha make your tea bubbly. One certain yeast found is called Saccharomyces boulardii. It is used as the number one pro biotics used in hospitals, called  florastor. It is abundant in kombucha and believe me when I tell you that you need this in your body. It helps a myriad of processes.

We don’t talk a lot about yeasts except for Candida so most think that yeasts are bad in general and this is not true. Yeasts just like bacteria are very important and can help strengthen the body. When harmful yeasts become dominate and the good yeast are weakened, that is when trouble ensues. Yeasts, when they are establishing dominance within you, do this by shooting at each other until one becomes dominate by destroying the other. Think of it like a shoot out in the old corral.  One will remain and dominate the other will diminish.

It’s all about the fizz.

Enough about these good yeast and back to how to make your tea bubbly. The yeasts eat the sugar and make carbonation. When they run out of food they die off and then your kombucha turns to vinegar and you will lose your carbonation. So the secret is to get your kombucha right when it is not too sweet but not sour. This is the perfect time to drink kombucha and also has the most benefits. Many think the more sour it is the better. This is not true, because then you lose the yeast that help your body flourish because they have died off.

If you want super bubbly fruit flavored kombucha, here is the trick. Make your first fermented kombucha tea. Don’t let it get overly sour. Bottle it with your fruit juice when it is still just a tiny bit sweet. Add your juice and cap off the air by placing in bottles and the yeasts will go crazy eating the sugars out of your tea and making you lots of bubbles. When it turns too sour on your first ferment the yeasts have died and can’t do their job of making your tea bubbly. When you cap off the air in your second ferment they do their job more efficiently. This is why it is usually more bubbly than the first ferment.

One more time:

  1. Make a batch of kombucha. Don’t let it get too sour. It should still be a tiny bit sweet. You can stop here and bottle it or ferment again with juice.
  2. To add fruit flavored. Add your fruit juice to your bottles, then add your kombucha tea and cap. Let this sit for one to three weeks. This depends on the temperature of your home. Sometimes it can be done in a few days, so check it often.
  3. Check your bottles after a few days to a week to see if they are to your liking and bubbly, or leave them to ferment longer.
  4. Place in the fridge when done.

Look closely, see the bubbles?

 

Don’t let it get too sour. That’s the secret to bubbly kombucha. Work with these yeast microbes and they will work for you. Give them the food they want and then they will consume the sugars so you don’t have to. In return they will give you bubbliness for all your effort. I love this so much! They do the work and I receive the benefits.

I am intense about the bubbles. It’s important to me. I  ♥ them.

    I ended up with a new scoby on the surface of each of my second fermentation bottles. What do I do with these new ones?

    • You can just pitch them or throw them in your garden.

        Hello Donna !

        I hope I am posting in the right place

        I am trying to find a quality glass jar with spigot for a continuous brew kombucha. The party type serving jars I am finding at bed bath and beyond, Marshall’s , etc all have silver plastic made to look like stainless, covering more plastic for the spigot. Ugh! I enjoy seeing the kombucha in action so the crocks just don’t get it for me.
        Any leads?

        Thank you
        Heather

    Hi there, Donna I’m new to the Health benefits of Kombucha and would like to start my own batch, however I’m still breastfeeding my 6 month old. Is it safe for me to drink Kombucha while nursing? And could my 4 year old have some as well? Just curious. Thank you!

    • I would wait just to be safe drinking it yourself since you are new to kombucha. But your 4 year can have it for sure. I would start with cultured veggies and other culture foods first and then after a month or so. maybe incorporate a little kombucha maybe a few ounces and then work up from there.

      • Deana says:

        Thank you! I’m excited that I found your blog. I love it. I’ve been tired for such a long time and know that this is what I need to be doing for my children and myself. I’m looking forward to learning more from you.

    Hi Donna,

    Thank you for this information. I was going to start my first batch ever of Kombucha today, but I got nervous because I wasn’t sure if I had the right type of glass jar. Is it fine to just use a gallon glass mason jar, and then for the second ferment pour the kombucha into cleaned, re-used “GT’s Kombucha” bottles? I want to work with what I have right now for financial reasons. Thank you so much for your response!

  4. Hi I started making kombucha in August. At first it was perfect and I had lots of bubbles. The last few batches have been too vinegar. I couldn’t drink them. I also had not many bubbles. If I start over how much starter should I save. I don’t like it to taste like vinegar.

    • The more starter you use the faster it will brew. So you can use2 or 3 cups and then check it often to see when it is done.

      • Maureen Russell says:

        Donna
        The more of the old starter I use (you say 2-3 cups) won’t it retain the vinegary taste?? My Kombucha has been just sitting since before Christmas. Want to have less vinegar taste.

        • The new batch if you add more starter will just brew faster and you can stop it when it is ready before it gets to vinegary. Or just add the normal amount and do it the normal time frame. Adding more starter will just make it brew faster, say 5 days instead of 7.

  5. Shellie says:

    Okay, so if it does go to vinegar, is it possible to continue the same scoby into another batch and start again? Or did I kill my scoby? :(

  6. Jennifer says:

    Can it get bubbly just from the first ferment, if you don’t want to add juice for a second ferment? Or is it necessary to do a second ferment to get the bubbles?

    • No it can be bubbly from the first ferment. Get it before it gets to tart that is when it is the most bubbly.

      • Jennifer says:

        I’ve been tasting it each day to see when it tastes right. I’m on day 8 right now, and it’s really close – if not ready. But, it doesn’t seem bubbly, so maybe it’s not ready. I know my water kefir gets extremely bubbly on the second ferment, but my kombucha isn’t. That’s why I asked about if it would only get bubbly on the second ferment.

  7. Cyndi says:

    I have a question about tea. I will be starting my very first batch of Kombucha tomorrow and will be using tea bags instead of loose tea. Many of the Recipes I have read call for 5 bags of tea for a gallon. The recipe i got with my scoby calls for 10. Is this just a personal preference? I hope that doesn’t seem too silly, but I haven’t ever tried kombucha. I have just been reading about it and decided to give it a try. Thank you!!

    • Here is my recipe. Its 3 1/2 quarts. I would follow my recipe because I know that it works. How much starter liquid do you have? This is important to know how much to make. Its important to use the right ratios because other wise it can cause problems when you brew your kombucha.

      • Cyndi says:

        There is about 1/4 cup of starter, and it says to use 1/4 distilled ACV for the first batch only to adjust the PH. I only have raw ACV which would probably not get along with my new scoby.

        • That is not a lot of starter and make take a while to culture and not culture right. I would make half of my recipe and then after that you can make the full recipe. I think this would work the best for you.

  8. Ann Wollman says:

    How long do you ferment the first batch of kombucha before you add fruit juice? I have never had bubbles but get foam. Is this similar?

    • Yes, it is similar. It can be anywhere from 6 to 13 days depending on how cold your home is and how strong your starter is? It shouldn’t taste sweet but not to tart either.

  9. Annette says:

    Hi Donna, I’ve been making a sugar syrup (water & sugar) and adding that to my tea and scoby. I have noticed less bubbles than my original 8 batches. It’s already been 2wks and there is a faint sweet and a very faint carbonation. This late into the process, Can I add more sugar syrup to get more bubbles?

    Thanks again for the wonderful article!

  10. Vicki says:

    Thanks Donna! This is helpful. My last batch – none of the bottles were bubbly at all. Was going out of town and didn’t want to come back to vinegar, so I guess I “rushed” them into the 2nd ferment. That being said, I don’t recall ever having my 1st ferment being bubbly. So what I am I doing wrong there? Been working at this for quite sometime and every batch is an experiment. Some good, some okay and some not at all. Could it also be that my flip top is not sealing good enough?? Oh and if I don’t have enough for a full bottle of 2nd ferment and only fill it part way, will that mess it up too?

  11. Bruce says:

    Great article as usual, Donna. Thanks! But there are a few missing pieces of information. For example, what is the best ratio of fruit juice to kombucha? My problem has often been too much carbonation. In the past we’ve used 1/2 ounce, 1 ounce, and 2 ounces of fruit juice for a sixteen ounce bottle, but frankly, those have been nearly explosive. Are we using too much? Not enough? What would work best?

    Second, how much air space do you recommend be left in the bottle for the second fermentat? I usually fill about half way up into the neck of a sixteen ounce Grolsch bottle which leaves maybe an inch and a half of air, but should there be less or more? Should the neck be filled completely allowing just 1/8 inch or less from the top? Or should it be more like two to three inches? Inquiring minds need to know.

    Thanks!

    • Hi Bruce. It really depends on how sweet your first batch of kombucha is. This is the kombucha before you add the juice. If it is to sweet it will ferment more when you cap off the air and then become extremely carbonated. It should just be a little sweet but mostly the sugar should be gone. If it is really sweet add less juice and let it ferment a shorter time and check the bottles regularly.You can let your 1st ferment go till there is no sweet taste but not vinegary and then I would add 2 ounces of juice. If it is a little sweet I would add less juice and 1/2 to 1 ounce.

      Fill it almost to the neck of the bottle. This is the best. The more room for air the more explosive.

      Great questions Bruce. You have always been one of the best at asking questions and one of my favorites to answer back.

      Always a pleasure my friend. Keep the questions coming!

  12. Amanda says:

    Ooohh that animation is so great! I love the bubbles. This is indeed a helpful post. I’m thinking that maybe I let my first ferment go too long then. That might explain why it isn’t always bubbly after the 2nd ferment. It still doesn’t explain why I sometimes experience a loss of carbonation simply by chilling it. When I put it in the fridge it is obviously bubbly but loses the bubbles after chilling. Could a day of chilling really be too long to overferment and lose the bubbles?
