This Coffee Kombucha is one of my favorite flavors and will be in my repertoire for many brews to come. The combination of kombucha and coffee is truly delightful.
I used a secondary fermentation process for this recipe, which is a great way to make a guaranteed batch of drinkable kombucha.
I was going to try using coffee in the first fermentation instead of black tea, but after reading about all the things that could go wrong, I didn't want to chance it.
Coffee contains oils and is highly acidic, which is why it can be a disaster.
Making your own flavored kombucha is cheaper than store-bought, so if you love kombucha as much as I do, it's totally worth brewing your own.
Other yummy coffee recipes are my Vegan Chocolate Truffles with Coffee, Superfood Latte, Carbonated Iced Coffee recipe, and my Cold Brew Cacao Coffee.

❤️ Why You'll Love It
- This foolproof coffee kombucha combines two great drinks into one. It's perfect for coffee lovers and kombucha lovers.
- It is a refreshing flavorful pick-me-up.
- Making your own coffee kombucha is cheaper than store-bought kombucha.
Two Types of Fermentation
The first fermentation of kombucha is when you combine sweetened tea, a kombucha scoby (symbiotic culture of bacteria and yeast), and some starter kombucha tea. You let it ferment for 7-21 days and the result is uncarbonated unflavored kombucha.
For the second fermentation, you remove the kombucha culture and take that raw kombucha you made in the first fermentation, and add flavor. You let it ferment for another 3-5 days in sealed bottles. The result is a fizzy-flavored drink.
You can ferment the flavored kombucha for up to 14 days. It all depends on the amount of sugar content in the flavor you're adding, and the temperature of the room.
Warmer temperatures will cause faster fermentation, and higher sugar content will also speed up fermentation.
What Makes Kombucha Fizzy?
The second fermentation is when kombucha gets fizzy. By putting it into a sealed container at room temperature and adding a sugar source (fruit and/or sweetener), carbon dioxide builds.
🧾 Ingredients
- Homemade kombucha: You'll need freshly made kombucha that has not been refrigerated yet. I used kombucha made with black tea. You could also try green tea kombucha. I haven't tried it yet so I cannot speak to the outcome.
- Unsweetened coffee: I used cold brew coffee because that's what I drink daily. It is less acidic than other brews. You could also use freshly brewed coffee, just make sure to cool the hot coffee to room temperature.
- Maple syrup: Adds sweetness. You could also use agave syrup, sugar syrup, or your favorite sweetener.

🥣 Supplies
- Funnel
- 4 (25 ounce) bottles with flip-top lids
- Measuring cup
🔪 Instructions
Step 1: Pour ¼ cup cold brew coffee into each bottle.
Step 2: Pour ¼ cup maple syrup into each bottle.
Step 3: Pour your homemade kombucha into the bottles, leaving 1-2" head space. Let sit 3-5 days at room temperature out of direct sunlight.
Step 4: Pop open the lids at least once a day. Pressure builds, and this allows it to escape.
Should I Burp My Second Ferment Kombucha?
Yes! If you don't you could have a mess. By adding sugar to the homemade kombucha and fermenting it a second time in flip-top bottles, you're creating an environment for carbonation. If you don't allow it to escape, you'll have kombucha all over your kitchen.
How Long Does It Take To Get Fizzy Kombucha?
It can take anywhere from 1-14 days. It depends on a few things.
- It depends on how much sugar you have in the kombucha. (Sugar in the form of fruit and/or sweetener.) The more sugar, the faster you'll get carbonation.
- It also depends on the weather. Warmer temperature = faster carbonation. I've had bubbly kombucha after a day in summer months and bubbly kombucha after a week in colder months.
💭 Tips
- I recommend using cold brew coffee for this recipe since it's a lot less acidic. I pretty much only drink cold brew coffee, so I didn't even try this with regular coffee.
- Refrigerate after the kombucha is done fermenting.

Nutrition
*Note: Nutrition information should be considered an estimate only. Different nutrition calculators give you different results.
**Important! If you are gluten free you may want to avoid coffee altogether. I personally have never had a problem drinking it, and I have a gluten intolerance. It is probably because I drink whole bean organic coffee, and grind it myself. I learned that it can be problematic for people who don't tolerate gluten. So I did some research and one article mentioned to try organic whole bean coffee because it isn't highly processed causing cross-reactivity issues. So please do the research yourself, and test it out. I try to only post recipes that are 100% gluten free since I have a gluten intolerance. I am really careful about avoiding gluten in my daily life.

Am definitely going to try this! Just a comment though, I've always used half gallon mason jars for my kombucha forever and get a beautifully fizzy end product!
