How To Make Watermelon Kombucha

To make watermelon kombucha, you’ll need fresh watermelon, sweetener, tea, and a SCOBY, plus a little patience for the fermentation process.
 
Watermelon kombucha is one of the most refreshing summer ferments you can make at home.
 
The sweet, juicy flavor of ripe watermelon pairs beautifully with the tangy fizz of kombucha.
 
And the best part is, you don’t need fancy equipment to make watermelon kombucha.
 
If you’ve been wondering how to make watermelon kombucha that actually tastes good and fizzes properly, this guide will walk you through it step by step.
 
In this post, we’ll cover how to make watermelon kombucha, from brewing the base tea to bottling your watermelon kombucha for that perfect second ferment.
 
Let’s dive in.
 

How to Make Watermelon Kombucha: The Basic Steps

Learning how to make watermelon kombucha starts with understanding the two-stage process.
 
You first ferment sweet tea with a SCOBY to create plain kombucha.
 
Then you add watermelon juice during the second ferment to flavor your kombucha and create carbonation.
 
Here’s what makes this process work so well.
 

1. Brew Your Base Kombucha First

To make watermelon kombucha, you need plain kombucha as your foundation.
 
Brew black or green tea, dissolve sugar while it’s hot, and let it cool completely.
 
Add your SCOBY and a cup of starter kombucha from a previous batch.
 
Cover the jar and let it ferment for 7 to 14 days.
 
The warmer your room, the faster your kombucha will ferment.
 
You’ll know your base kombucha is ready when it tastes tart and slightly vinegary.
 

2. Prepare Fresh Watermelon Juice

While your kombucha ferments, you can prep your watermelon.
 
Cut a ripe watermelon into chunks and remove the seeds.
 
Blend the chunks until smooth, then strain the juice through a fine mesh sieve.
 
You want pure juice without too much pulp for your watermelon kombucha.
 
About one cup of watermelon juice works well for a gallon batch of kombucha.
 
If you’re making a smaller batch, adjust the amount accordingly.
 

3. Combine and Bottle for Second Ferment

Now it’s time to make watermelon kombucha fizzy and flavorful.
 
Pour your finished plain kombucha into bottles, filling each one about halfway.
 
Add your fresh watermelon juice to each bottle.
 
Fill the rest of the way with more kombucha, leaving about an inch of headspace.
 
Seal the bottles tightly and let them sit at room temperature for 2 to 4 days.
 
This second ferment is where watermelon kombucha gets its bubbles.
 

Tips for Making Watermelon Kombucha Taste Amazing

Knowing how to make watermelon kombucha is one thing, but making it taste amazing is another.
 
These tips will help you get the most out of your watermelon kombucha.
 

1. Use Ripe, Sweet Watermelon

The flavor of your watermelon kombucha depends heavily on the fruit you choose.
 
Pick a watermelon that’s deep red and sweet.
 
Underripe watermelon will make your kombucha taste bland.
 
You can also add a few fresh mint leaves to your watermelon kombucha for extra freshness.
 

2. Don’t Overdo the Sugar

Watermelon already contains natural sugars that feed the yeast during fermentation.
 
When you make watermelon kombucha, you don’t need to add extra sugar beyond what’s in the juice.
 
Too much sugar can cause your watermelon kombucha to become overly fizzy or even explode.
 
Keep it simple and let the watermelon do the work.
 

3. Burp Your Bottles Daily

Carbonation builds up quickly when you make watermelon kombucha.
 
Open your bottles once a day to release excess pressure.
 
This prevents your watermelon kombucha from becoming a sticky mess on your kitchen ceiling.
 
Once you get the fizz level you like, move your watermelon kombucha to the fridge.
 

4. Strain Before Drinking

Some pulp might make its way into your watermelon kombucha.
 
If that bothers you, strain your watermelon kombucha through a fine sieve before serving.
 
Or just embrace the rustic texture and enjoy it as is.
 

Common Mistakes When You Make Watermelon Kombucha

Even when you know how to make watermelon kombucha, a few common mistakes can ruin your batch.
 
Here’s what to watch out for.
 

1. Using Tap Water with Chlorine

Chlorine kills the beneficial bacteria and yeast in your kombucha.
 
Always use filtered or distilled water when you make watermelon kombucha.
 
This keeps your SCOBY healthy for future batches.
 

2. Fermenting Too Long

Watermelon kombucha can turn sour if you let it ferment too long.
 
Taste it every day during the second ferment.
 
When it tastes balanced and fizzy, it’s ready.
 

3. Skipping the First Ferment

You can’t make watermelon kombucha without a properly fermented base.
 
Rushing the first ferment leads to weak, flavorless kombucha.
 
Give your base kombucha the time it needs before adding watermelon.
 

So, How Do You Make Watermelon Kombucha?

To make watermelon kombucha, you brew a plain kombucha base, add fresh watermelon juice, and let it carbonate during a second ferment.
 
It’s simple, refreshing, and perfect for hot summer days.
 
Now that you know how to make watermelon kombucha, you can experiment with mint, lime, or even a hint of ginger.
 
Once you get the hang of it, making watermelon kombucha at home becomes second nature.
 
So grab a watermelon, fire up your brew, and enjoy your own homemade watermelon kombucha.
