How to make your own Kombucha

Here is all you need to know to make kombucha at home! You'll see that it's easy, quick and delicious.


Make kombucha in 5 easy steps

  1. Make a sweet tea
  2. Add a kombucha scoby (starter)
  3. Leave to ferment on the counter
  4. Add herbal tea or juice (optional)
  5. Enjoy!



  • Makes 3 liters of kombucha
  • Preparation: 15 minutes
  • Fermentation: 5 to 15 days




  1. Place the tea bag in the jar.
  2. Pour 500 ml of boiling water into the jar, infuse for 15 minutes, then remove the tea bag.
  3. Add sugar and stir until dissolved.
  4. Pour filtered water until you reach the 3 liter level (your tea is now lukewarm).
  5. Add the Mamma Kombucha with its liquid culture.
  6. Cover the container with the cloth, and tie with the elastic.
  7. Leave to ferment for 10 to 15 days at room temperature. This is the first fermentation (F1).
  8. Taste regularly starting on the 5th day. As soon as your sugar and acidity level is to your liking, it's time to flavor (optional) and bottle the kombucha.

Bottling kombucha

  1. Set aside the kombucha scoby and about 2 cups (500ml) of liquid aside, in an airtight container in the refrigerator.
  2. Pour the rest of the kombucha from the jar into pressure-resistant bottles.
  3. Keep bottles at room temperature for 3-4 days. This is the second fermentation (F2).
  4. When it is sparkling (watch out for the pressure), put in the fridge.

And there you go! Your kombucha is now ready to enjoy!




Plain kombucha is delicious, but you will probably like to give it more taste and flavor. You can add herbal tea, flavored tea, fruit juice, vegetable juice, frozen fruit, honey, or other ingredients to your taste.

When to flavor?

We recommend that you flavor your kombucha just before bottling. Before adding ingredients to your kombucha, remember to remove the mother and part of her liquid and set them aside. In doing so, you will always have plain kombucha to start your next batch.

However, it is also possible to brew kombucha with a flavored tea from the first fermentation (instead of plain tea). However, this may weaken your scoby (it dislikes the essential oils of certain plants). In addition, most of the flavors will disappear during this primary fermentation. It is better to add the flavors just before bottling.

How much to use?

To add flavor, the proportion to follow is 10 to 20% of ingredients to 80-90% of kombucha. So, if you have just finished producing 3 liters of kombucha (recipe above), then you can add between 300 and 600 ml of herbal tea or juice.

These percentages are just an estimate. You will have to do your own tests. Some ingredients require much less than 10% (like ginger juice, for example).

Can I add sugar?

If your kombucha is too low in sugar for your taste, you can add it at this stage. However, watch out for the pressure! The addition will also have the effect of promoting the development of carbon dioxide in your bottles.





  • 3 liters of plain kombucha, freshly prepared (recipe above)
  • 400 ml pineapple juice


  1. Mix the kombucha and pineapple juice.
  2. Taste, then add more pineapple juice as needed.à
  3. Bottle the kombucha (as described in the Bottling chapter above)



Short shelf life (<2 months)

For a shelf life of a few weeks, keep your mamma in your fermentation jar, with 500 ml of kombucha from your last recipe.

The kombucha will become very vinegary and will be perfect as a new culture (starter) for your next recipes.

Longer shelf life (> 2 months)

Option 1 (at room temperature):

Follow the same instructions as the short self life method, and feed your culture once a month with a sweet tea.

To do this, just remove and replace some of your culture with the same amount of sweet tea. If you don't have tea, just add sugar.

Option 2 (refrigerator):

If option 1 is not suitable for you, you can keep your mamma and her liquid culture in a cool place (refrigerator) in an airtight container. Your culture will "fall asleep" and will not need to be fed. This option can be used to keep your mamma kombucha for many months. However, there is a risk that eventually it will lose its vitality.




What is the best tea for kombucha?

Kombucha likes plain tea. The tea used must come from the Camellia sinensis plant, because the kombucha culture feeds on its tannins. You can use black tea, oolong tea or green tea.

How much sugar to add to tea?

You need 60 to 80 g per liter of kombucha (white or brown). You can try with less if you wish; however, about 80% of this sugar will be consumed by yeasts and bacteria. Sugar is essential for the fermentation of kombucha!

Other types of sweeteners (stevia, honey, maple syrup, etc.) can only be added during the second fermentation to add flavor.

Which water to use?

Water should be as chlorine-free as possible. If you don't have a filter, you can let the tap water sit for two hours in a jar. The chlorine will evaporate.

How much culture to use?

You should use at least 10% liquid culture per recipe, and ideally 15-20%. So to make 3 liters of kombucha, you need to add at least 300 ml of liquid culture + your mother, ideally 500 ml. If you don't have enough liquid, top it off with store-bought kombucha.

What is a first and second fermentation (F1 and F2)?

The first fermentation (also called F1) is the stage during which tea is transformed into kombucha. Secondary fermentation (also called F2) is the stage during which kombucha ferments in bottles at room temperature. It is at this stage that carbon dioxide accumulates in the bottles. The second fermentation is stopped (or rather very slowed down) when the bottles are placed in the fridge.

How to have bubbles?

The kombucha becomes sparkling during secondary fermentation (F2). To have bubbles, you must place the kombucha in airtight and pressure-resistant bottles and let it ferment for a few days.

For more information, see the article on how to make a sparkling kombucha.

If your kombucha is too bubbly or if you want fewer bubbles, see the article on how to have fewer bubbles in your kombucha.
