Making your own homemade kombucha is easy and fun. Adding flavors to the kombucha is even more fun because you can customize it to suit your tastes.

Kombucha is really refreshing, so it's the perfect drink for summer. This Blueberry Hibiscus Kombucha is a good non-alcoholic option at a party.

If you prefer black tea in the first fermentation, try my Blueberry Kombucha.

Some other hibiscus kombucha recipes I've made are Raspberry Hibiscus Kombucha and Blueberry Hibiscus Kombucha.

If you love hibiscus try my Jamaica Tea Recipe (Hibiscus Tea) recipe or my Hibiscus Lemonade Chia Fresca. Both are great for summer.

To make a cocktail or mocktail, try my Raspberry Shrub Drink or Berry Shrub Drink. Another blueberry recipe to try is my Blueberry Coconut Ice Cream.

Two Types of Fermentation

The first fermentation of kombucha is when you combine sweetened tea, a kombucha scoby, and some starter tea. You let it ferment for 7-21 days and the result is uncarbonated unflavored kombucha.

For the second fermentation you remove the scoby and take that 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 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

This is an overview of the ingredients. To see the full list of ingredients with measurements and instructions, see the recipe card at the bottom of this post.

Homemade hibiscus kombucha: You'll need freshly made hibiscus kombucha that has not been refrigerated yet.
Blueberries: You can use fresh or frozen blueberries.

🥣 Supplies

Funnel
4 (25 ounce) bottles with flip top lids
Measuring cup

🔪 Instructions

Smush ½ cup fresh or frozen blueberries into each bottle. Pour your freshly fermented hibiscus kombucha into the bottles, leaving 1-2" head space. Let sit 3-5 days.
Pop open the lids at least once a day. Pressure builds, and this allows it to escape.

The video below is for homemade kombucha with black tea, but the process is the same:

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 a second time in bottles with swing top lids, 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 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

Strain the berries out after fermenting, if desired.
Use bottles with swing top lids! Mason jars and store-bought kombucha bottles that have the seal broken won't hold carbonation.
You can add maple syrup, agave syrup, brown sugar, white sugar, or another sweetener.
Refrigerate after the kombucha is done fermenting.
