This fruity refreshing Mixed Berry Kombucha is the ultimate drink for summer. Made with three kinds of berries.

This Mixed Berry Kombucha can be made any time of the year since it can be made with fresh or frozen berries.

It is sweet, tart, and refreshing. Since it's a second fermentation kombucha it is fizzy from carbonation.

You can make it sweeter by adding maple syrup or your favorite sweetener.

❤️ Why You'll Love It

It is sweet and tart.
It's made with fresh or frozen berries, so you can have it year-round.
It's cheaper than store-bought kombucha and you can control the ingredients.

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 the 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.

🥣 Supplies

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

🔪 Instructions

Mixed berries being poured into a funnel into a bottle.

Step 1: Smush ½ cup fresh or frozen mixed berries into each bottle.

Kombucha being poured into a funnel over a bottle.

Step 2: Pour your freshly fermented homemade kombucha into the bottles, leaving 1-2" head space. Let sit 3-5 days.

Step 3: 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 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 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

Refrigerate after the kombucha is done fermenting.
If you don't want chunks of berries, you'll need to strain after the kombucha is done fermenting or when pouring yourself a glass.
