Why Make Homemade Kombucha?
Wondering why and how to make kombucha at home? Got “a kombucha problem” and don’t like how much it costs? I don’t blame you. Store bought kombucha costs as much as wine.
1 gallon kombucha = $28 Store bought vs. $0.80 Homemade = 30 times cheaper
Shocked? I was too. This reason alone should be enough to get over any aversion towards kombucha SCOBY, the jellyfish like slimy kombucha “mushroom”, and learn how to make your own kombucha.
I have been making my own kombucha for 5 years now. Making kombucha at home is super-super simple once you understand how kombucha tea brewing process works. This post goes into detailed instructions including a video, supplies needed (with affiliate Amazon links I use and trust myself) and a huge section of FAQs.

What Is a Kombucha Tea?
Kombucha tea is a fermented tea made with water, tea, sugar, bacteria and yeast. After kombucha SCOBY (mushroom) sits in a sweetened tea for 7-10 days, the result is barely sweet fermented fizzy drink. Most sugar in store bought kombucha comes from added sugar.Kombucha definitely tastes and smells like a fermented product. Something in between apple cider and tea. It tastes depends on type of tea leaves used and flavorings added. There is a big difference in taste between green tea and black tea fermented tea.
Ingredients and Supplies You Will Need
- Kombucha SCOBY: You will need to grow your own SCOBY first from a mix of a bottle of store-bought kombucha, tea, sugar and water. However, you can buy fresh SCOBY with starter tea to speed up the process by 2-3 weeks or get one form a friend.
- Tea: Any caffeinated, flavoured (love Earl Grey tea here) or plain tea like white tea, black tea or green tea works. No decaf tea. You can also use tea bags (I list the amount in the recipe card below).
- Sugar: White or cane sugar, preferably organic. No brown, coconut or raw sugar. Also no honey, maple syrup, stevia, splenda etc.
- Water: Can be just tap cold water, doesn’t have to be filtered.
- Large glass container: Has to be glass or ceramic minimum 1 gallon size. I always use a glass dispenser with a plastic spout (which is fine!) that makes pouring the brewed kombucha so much easier.
- Flip top glass bottles: Airtight bottles will keep carbonation in.
- Fine mesh sieve: Filters out large and small loose leaf tea leaves making your drink super clear.
- Linen or paper towel and a rubber band: You want to allow air to circulate during the fermentation process.
Bottles cleaning tip: With time inside of the bottles accumulate a tea build up. Add 1 tsp baking soda and 1 tbsp uncooked rice, then fill up with hot water half way. Shake, let stand fo 10 minutes, shake well again and rinse. Bottles should be much cleaner now.
How to Make Kombucha from Scratch
Here is a quick recap of the whole process:
- Grow or buy a SCOBY
- First fermentation – brewing kombucha.
- Second fermentation (optional) – flavoring and making kombucha more fizzy.
1. Grow or Buy Fresh SCOBY with Starter Tea
Here is a super easy video recipe how to grow kombucha SCOBY. Quick recap: All you will need is a bottle of store-bought kombucha, combined with a few cups of homemade sweet tea and left to ferment for about 2 weeks or until a SCOBY forms on top. Or you can buy fresh SCOBY with starter tea these days. Amazing!
You might be able to grow a SCOBY with store-bought flavoured kombucha. Just make sure it contains black tea. For example, I think ginger kombucha will have more chances than mango one.
2. Brew Sweet Tea
Now that we have kombucha mushroom, we are ready to brew kombucha also called “first fermentation”. In a large pot, bring water to boil and turn off heat. Add tea leaves and sugar, stir and let cool completely.
To speed up the cooling process, place pot in a sink filled with cold water for 30 minutes, or let cool outside (if it’s cold). I use the same pot each time when making kombucha, so now I do not have to measure 14 cups of water every time.
3. Combine Tea and SCOBY
In at least one gallon size glass beverage dispenser, add SCOBY and 2 cups of starter tea (the one from growing a mushroom in or store-bought kombucha). Pour cooled tea on top using a fine mesh strainer.
Once you pour freshly brewed tea, it is normal to see the SCOBY sink to the bottom or hang sideways. It will float to the top after a few days of fermentation.
Cover with paper or linen towel secured with a rubber band and put in a place with temperatures around or above 21C or 70F degrees (I leave mine on a kitchen counter away from direct sunlight) to ferment for 7-14 days.
How do I know my kombucha is brewing? Kombucha will lighten in colour and develop fermented smell. You will also see small bubbles forming and new SCOBY forming on top of the first one.
In summer, warmer temperatures speed up the fermentation. And in winter, they slow it down. Keep an eye on the kombucha based on the season and your house temperatures.
5. Taste and Bottle
After 7-10 days (less in summer) start tasting kombucha. If it isn’t sweet, has a tangy taste, fizzes as you pour and booch mushroom is floating at the top, then your fermented tea is ready. Pour all of it, minus the 2 cups and SCOBY, using a funnel into an airtight cap bottles and enjoy!
6. Storing Kombucha Tea
Does kombucha go bad? Kombucha tea doesn’t go bad but rather keeps fermenting which makes it taste more vinegar-y. Choice of storage depends on your personal taste buds. Keep at room temperature for up to one week, “burping” bottles every few days to avoid gases build up. After that (or from the start) refrigerate for up to 2-3 weeks. Fermented tea loses its carbonation when refrigerated and doesn’t need “burping”.
There is nothing like freshly brewed kombucha. When it’s ready for bottling, I like to pour myself a big glass directly from the dispenser with a spout before bottling the rest up.
Always leave about 2 cups of fermented tea covering the SCOBY in a jug, to keep it hydrated and to be able to start a new batch. To brew next batch, start with step 2 by brewing and cooling the sweet tea.
Health Benefits of Fermented Tea
One word – PROBIOTICS. Kombucha is a fermented product containing the “good” bacteria.
- Stronger immune system.
- Improved digestion.
- Healthy gut.

How to Flavor and Make Kombucha More Fizzy
Freshly poured kombucha tea from the dispenser with a SCOBY is very fizzy. It loses its carbonation once bottled, especially in a fridge. Would you like it to be more fizzy? Then you need to do a second fermentation aka how to make kombucha fizzy.

Homemade Kombucha FAQs
Unfortunately not. Kombucha is one of few recipes where you have to use white or cane sugar. Raw sugar, coconut sugar, honey, maple syrup, stevia or any other sweetener will not work. However, you will not be eating 1 cup sugar once tea has fermented. The sugar acts like the food for the bacteria and yeast. They will eat it all up turning into acidity and carbonation. Final kombucha is very low in sugar.
No, caffeine is a must for the fermentation process to occur. You can combine a bit of flavored tea with black or green or white tea to add flavor.
No and yes. I don’t rinse the mushroom but if you want to – go for it. Every few batches I wash the jug with biodegradable dish soap (check out the non-toxic cleaners I use). I have read that you should wash jar with vinegar but because I don’t use conventional harsh dish soap, I am not too scared of the chemicals making my SCOBY “sick”.
I honestly never had this issue. Neither any reader has reported it. So it is very rare and what you might think is a mold, is actually new SCOBY growing on top. But if it happens, you have to discard the entire batch and start over again.
That is a new SCOBY growing – “a baby”.
Always leave the top (newer) kombucha mushroom to keep brewing kombucha. Peel off the older one and you have 2 options:
Option #1: Give it to friends or start another batch.
Option #2: Compost it. It sucks, it’s a waste but at least it gets composted.
Yes, SCOBY is easy to cut with a pair of clean kitchen scissors. In fact, you always should keep only a few SCOBies in your kombucha brewing batch because too many and your fermented tea will be sour. Think of it as a bigger hungry “baby” that will eat sugar faster. However, you should also keep in mind that for best carbonation results the shape of a SCOBY should be the shape of the jar creating a tight seal.
Yes, technically. I have seen scoby candy recipes and have heard some folks feeding the mushroom to their dog.
To maintain a bit of a fizz, store kombucha at room temperature (not refrigerated) in an airtight bottle. Carbonation won’t be as strong but still some is better than none.
When we went on vacation to Mexico for a month, I placed the jug with SCOBY and about few cups of kombucha in the fridge for 4 weeks. This way the fermentation process slows down. If I want to take a break for a shorter period of time while at home, let’s say 7-10 days, I just let the jar sit on a counter in the same way.
Yes, a bit. It contains approximately 1/3 the amount of caffeine as the tea it is made with.
Alcohol level in kombucha is 0.5% ABV compared to 5% ABV in beer. Definitely won’t make you drunk.
Drink as much as desired. There is no right or wrong formula for health benefits. Make sure to drink plenty of water as kombucha is natural detoxifier. And you want to flush the newly released toxins out.
Yes for sure. My kids love the booch, especially the flavored one. They treat it as pop or juice.
You let it ferment too long. Happens to the best of us. I usually make a few cups of strong sweet tea, let cool and add to the jug with the booch. Let sit for another 1-2 days, taste and bottle. Do not add sugar directly to the jug with kombucha as it will not dissolve or help with the acidity.
Black tea. Its leaves that have been oxidized for a long time creating a bold flavor.
Choice of storage depends on your personal taste buds. Keep at room temperature for up to one week, “burping” bottles every few days to avoid gases build up. After that (or from the start) refrigerate for up to 2-3 weeks. Fermented tea loses its carbonation when refrigerated and doesn’t need “burping”.
