How to Second Ferment Kombucha (+ Flavor Variations)

If you’ve been making homemade kombucha, the real fun begins when you try a second ferment. Second-ferment kombucha is what gives you that bubbly fizz we all love, plus it’s where you can play with flavor, like this cherry almond “Dr. Pepper” version. Not only does it taste amazing, but it’s a simple way to make your homemade kombucha feel special and refreshing, right from your own kitchen.

What Makes This Recipe Unique?

If you’re new to this process, you might be wondering why go through the trouble of a second ferment. Let’s talk about that for just a second.

  • Delicious Soda Alternative - If you’ve been trying to kick the soda habit (and let’s be honest, that can be hard), this recipe is a game-changer. The cherries and almond extract mimic that Dr. Pepper taste—without all the corn syrup and chemicals.
  • Versatile - Once you know how to do a second ferment, you can get creative—using different fruits, juices, herbs, and spices (see below for more specifics). Kombucha also works great as a starter culture to make this sparkling apple cider recipe, from-scratch fermented ketchup, DIY homemade mustard, or even to ferment chicken feed!  
  • Gut Healthy Fizz - Kombucha is naturally full of probiotics, enzymes, and organic acids that support digestion and immune health. The second ferment not only adds flavor, it also boosts the bubbles we all love.

Because here’s the thing: this isn’t about perfection, it’s about progress. Once you get the hang of it, second fermenting becomes second nature.

Key Ingredients

Second ferment kombucha ingredients: plain kombucha, cherries, and almond extract.

A full ingredients list, including measurements, can be found in the recipe card below.

  • Brewed Kombucha - You can technically use unflavored store-bought kombucha, but honestly, it’s much cheaper (and tastier) to make your own at home.
  • Cherries - We love to use fresh sweet cherries from our trees when they're in season. When using fresh cherries, make sure the stems are removed, but feel free to leave the pits in. The pits actually lend a stronger almond flavor. Be careful not to use too many cherries. Filling the jar to about ¼ full is sufficient. Otherwise, the fermentation could become too active, and the pressure may break the jar.
  • Almond Extract - In the video, you will see that I don’t measure this. One thing I love about this recipe is that it’s not an exact science, and measurements do not need to be perfect.
  • Sugar - Sugar reacts with the yeast in your kombucha, creating fizzy carbon dioxide. But don't worry, some of the sugar will be consumed in the fermentation process, so you aren’t drinking as much sugar as you added. 

Recipe Variations

This is where you can make second-ferment kombucha your own:

  • Dehydrated or Freeze-Dried Cherries - When our trees aren't producing, we love using the dehydrated or freeze-dried cherries from our summer harvest.
  • Juice - Flavor with juice instead of whole fruit (just stick to about 15–20% juice per bottle).
  • Other Fruits - Use other fruits like peaches, pineapple, mango, or berries.
  • Other Extracts - Swap in different extracts like homemade vanilla extract, as well as chocolate, orange, lemon, or maple extract.
  • Herbs and Spices - I love incorporating herbs from my cottage garden into my recipes. Try lavender and peach, mint and citrus, or apple with cinnamon and cloves.

How to Second Ferment Kombucha

Step 1: Place cherries in the bottom of a clean quart jar or swing-top bottle.

Step 3: Pour in kombucha until the jar is full.

Step 4: Cap the jar tight with a two-part jar lid or secure the swing-top lid, and leave it on a countertop in a warm room for 3-5 days. Periodically check the pop-top on the lid or look for signs of carbonation. If the two-part Mason jar lid no longer pops, burp the jar by releasing a bit of air out of it, and then screw the cap back on tight. For your swing-top bottles, you can just open and reclose the lid quickly.

Step 5: After 3-5 days on the counter, your kombucha should be bubbly and showing signs of carbonation. Strain the kombucha into a bottle or leave it in the jar.

Storage Instructions

Once your kombucha has the level of fizz you want, move it to the fridge. Cold storage slows fermentation and keeps it from exploding bottles (yes, that can happen if left too long at room temperature). For the best flavor, drink it within 1–2 weeks.

FAQs

What is Secondary Ferment Kombucha?

A secondary ferment is when you take fully brewed kombucha, remove the SCOBY, add fruit or flavoring, seal it up, and let it ferment again for extra carbonation and flavor.

What does the second fermentation of kombucha do?

Fermenting kombucha again with added fruit, juice, extracts, or herbs results in an amazing flavor and even more carbonation than the first time.

How long do you 2nd ferment kombucha?

Usually 3–5 days, depending on your home temperature. Warmer = faster.

What should I add to my second fermentation kombucha?

Pretty much anything! Fruits, juices, herbs, and spices are all fair game.
