How to Make Kombucha At Home

How to Make Your Own Kombucha at Home

Kombucha is sweetened tea that has been fermented by a culture; a symbiotic colony of bacteria and yeast – a.k.a SCOBY or “mother”. Despite its foreign (and somewhat off-putting) appearance, this colony of bacteria and yeast transforms sweetened tea into a tangy health elixir naturally rich in vitamins, minerals, enzymes and probiotics. Although sugar is used in the making of Kombucha, the end product has virtually no sugar content because it serves as food for the bacteria and fermentation process.

This ancient tradition of fermenting sweetened tea is believed to have many health benefits, one of which is improved digestion as a result of the naturally occurring probiotics. Probiotics provide your gut with healthy bacteria, helping to improve digestion by decreasing inflammation and increasing nutrient absorption.

Dr Axe shares his thoughts on Kombucha

Research suggests that inflammation plays a significant role on bone turnover and therefore contributes to osteoporosis.¹ Studies indicate that the factors involved with inflammation are directly linked with the critical factors of bone remodeling.¹ In short, inflammation increases osteoclast activity, the cells that dissolve bone thereby increasing your risk of osteoporosis.  Furthermore, inflammation in the gut reduces absorption which deprives your body of the nutrients you need to maintain healthy, strong bones.

While most of the beneficial effects of Kombucha have been studied in experimental models only, Kombucha drinkers around the world testify some of the benefits of the tea include:²

  • Reduce cholesterol level
  • Reduce atherosclerosis
  • Reduce blood pressure
  • Reduce inflammatory problems
  • Alleviate arthritis, rheumatism, and gout symptoms
  • Promote liver function and detoxify the blood
  • Normalize intestinal activity, balance intestinal flora
  • Regulate appetite, protect against diabetes
  • Stimulate glandular systems
  • Enhance the immune system
  • Improve hair, skin and nail health
  • Reduce stress and nervous disturbances
  • Improve eyesight
  • Counteract aging
  • Enhance metabolism

How to brew kombucha recipe

Kombucha is naturally rich in glucosamines which increase synovial hyaluronic acid production and aids in the preservation of cartilage structure.³ In addition to reduced inflammation, supporting the cartilage structure with glucosamines is a natural way to reduce arthritic pain.

One of Kombucha’s greatest benefits is the ability to detox the body, it is important to drink only a small amount when you first start and to drink more water throughout the day.⁴ As a result of the added beneficial bacteria and the dislodging of toxins in your bloodstream, temporary effects such as gas, stomach-ache, fatigue, rashes, diarrhea and headaches may occur. Drinking additional filtered water helps to excrete these toxins as quickly as possible.

It doesn’t take much to experience the many health benefits of Kombucha tea. Drinking one small glass each morning is a great way to start your day. You may be thinking, another expensive alternative health product – well not this time! Kombucha is so simple to brew at home, it is practically free!

Alexa, from our customer service team (maybe she’s helped you out over the phone before?) loves brewing Kombucha at home. Kombucha does wonders for your gut and is super refreshing too! I So I asked her to share her brewing secrets with you.

Here is what you need to to brew 4L:

Kombucha Supplies

  • 4 Litres Filtered Water
  • 4 Tea Bags*
  • 1 cup White Sugar
  • Kombucha SCOBY or “mother”
  • ½ cup Kombucha from previous batch

*Your Choice of Tea

As long as your tea is caffeinated, you can let your imagination run wild. Black tea produces a taste similar to apple cider vinegar. Green tea is very refreshing, also try White tea, Yerba Mate or matcha teas.

Brewing Equipment

You likely have most of these supplies and equipment already in your household.

  • 1 four liter glass jar or ceramic pot with a wide mouth
  • Pot to boil water and brew tea
  • Measuring cups
  • Sieve
  • Tightly woven cloth to cover ferment
  • Funnel
  • Bottles with close-able lids

Here is a great 3 min video explaining each piece of equipment

But wait –  What is the SCOBY or “mother” and where do you get one?   

The SCOBY (“mother”) is a Symbiotic Culture of Bacteria and Yeast. During the fermentation process, you will notice a clear or white film developing on the surface of the brew; this is the new SCOBY or “baby” forming. Sometimes the “mother” sinks, other times she floats and sometimes the mother is attached to the baby, but not necessarily. The “baby” SCOBY will become thicker the longer you leave it to ferment. Do not be alarmed if your first brew does not produce a “baby” – it may require a few brews to get going. The fermented tea is still nutrient-rich!

What came first – the Kombucha or the SCOBY? Getting started can be a little tricky because to brew Kombucha you require a SCOBY, however the SCOBY comes from the Kombucha… It can be difficult to imagine. Do not let this slow you down! The best way to acquire your starter SCOBY is to find a local friend who already brews and ask for an extra SCOBY plus ½ cup of their Kombucha.

Are you the first in your community to start brewing? No problem, SCOBY’s can be easily purchased online or made (with a little bit of patience) from a store bought bottle of Kombucha.

Okay, you’ve now collected up all the supplies and you’ve acquired your very own SCOBY. Time to get started:

Step One – Brew the Tea

How to make kombucha 01 pouring into jars

  • Boil water and sugar in a pot
  • Remove pot from the hot burner and add tea bags (let steep for 15 minutes)
  • Remove tea bags, let brewed tea cool to room temperature
  • Carefully transfer to glass jar or ceramic pot for fermenting

Step Two – Fermenting

How to make kombucha 04 SCOBY

  • Add your Scoby plus ½ cup Kombucha from previous batch to the sweetened brewed tea
  • Cover with a clean cloth (or coffee filter) and put in a room temperature place
  • Taste after 3 days. It will be a bit sour. Fermentation is sped up if the environment is warmer

When is the Kombucha done?

This is a matter of preference. Some people like it almost like vinegar, others prefer it younger and sweeter. Kombucha that is fermented for 8-10 days has “digested” all of the sugar from the batch – making it optimal for health.

What is floating around in the Kombucha?

As fermentation continues, you may see brown strains floating around in the Kombucha; these strains have detached from the “mother”. Some people like to drink them and others prefer to strain them out.

Step Three – Bottling

When you are satisfied with the fermentation of your Kombucha, carefully remove the “mother”and “baby” SCOBY and place them in a separate mason jar for storage. Remember to save ½ cup of this batch for next time.

Using a sieve and a filter, transfer your Kombucha into a clean, closeable glass container. Once bottled, you can leave the container on the counter for a few days to create a fizzier brew. To stop the fermentation process, store your bottles of Kombucha in the refrigerator.

Caring for your SCOBY

When your SCOBY is not actively fermenting a batch of Kombucha, just store her in some liquid from the previous batch in a jar, loosely closed, in the fridge.

    In the video, a bottle of kombucha explodes and shoots the fermenting liquid higher than the camera angle can show. Alexa laughs it off, and I’m glad she has a good sense of humor about it. However, as a senior citizen, the thought of having my kitchen ceiling, walls, counters, cabinets, and floors liberally sprayed with kombucha is rather daunting. I’d have to hire somebody to wash it all down. Realistically, why would I want to follow Alexa’s lead and take a chance on having that happen? Surely she is doing something wrong. …

    Hi Gloria,

    Those are definitely valid concerns. The woman in the video is actually not Alexa, but I have spoken with her and this is her reply:

    “It got super fizzy because after bottling, the kombucha was left out on the counter. I have actually never seen that before! The explosion was very big and intense. Kombucha does continue to get fizzy if not refrigerated so this may be the cause. Putting the kombucha in the fridge again slows the fermentation, even without SCOBY in the kombucha, there is small amounts of SCOBY usually floating in the liquid and will continue to ferment.”

    Hope that clears up any confusion!

    I make my own kombucha, it’s easy and fun to do. I like to flavour mine, lemon and ginger is my favourite but raspberry, orange, blueberry etc are all great as well. I would question putting the Scoby in the fridge, not recommended according to my research.

    Hi Evie,

    Great question! I’ve reached out to Alexa and this is her reply:

    “If you are not going to use the SCOBY right away for another brew, it is perfectly fine to store in the fridge, as it slows the fermentation process. If it has been in the fridge for a long time, allow SCOBY to come to room temp. before adding it to the room temp. sweet tea for a brew. If SCOBY has been in fridge for a REALLY long time, it will have a slow fermentation start and the SCOBY may not reproduce a baby scoby but the sweet tea will still be transformed into fermented tea.”

    My glass jar has a metal opener to release the tea can I use it or not

    Thanks for reaching out, Petra!
    When it comes to Kombucha, it’s best not to use metal as it can damage the kombucha. So metal is generally not recommended. Just glass is your best option. Hope this information helps!

    How do you make different flavours. I would like to incorporate ginger or turmeric

  12. Yoori AlgaeCal

    March 2, 2023 , 5:17 pm

    Hi Gayle,

    Ginger or turmeric flavor sounds like a great option! I’m happy to help!

    Gayle, you’re welcome to add in the flavor before covering the bottle with a clean cloth during step 2. Leave a little space at the top to add your flavors to allow breathing space.

    I hope this helps! 🙂 Please do let us know if you have any further questions.

    Can I use flavored teabags ( like black tea with current, etc) to make kombucha?

  14. Brianne AlgaeCal

    March 14, 2023 , 9:50 am

    Great question Tatiana,

    Feel free to experiment with different teas! That said, flavored teabags aren’t usually suggested, as they could contain things like essential oils that may negatively impact the cultures in your scoby.

    I hope this helps!
