What Is Wild Fermented Elderberry Soda?
If you want to take elderberry soda one step further, this is where things get really interesting.
Wild fermented elderberry soda is a naturally fizzy drink made by capturing wild yeast through a simple elderberry starter. As it ferments, it develops a light carbonation, a slightly tangy flavor, and a deeper, more complex profile than quick-mix versions.
It’s a more traditional, hands-on approach to soda, one that connects you a bit more to the process while giving you a drink that’s completely unique.

How to Make Wild Fermented Elderberry Soda
Ingredients
Wild Yeast Starter
100 g dried elderberries (about 1 cup)
100 g sugar
500 g non-chlorinated water
Elderberry Soda
3 liters water
1 cup fresh, dried, or freeze-dried elderberries
¼ cup sliced ginger (fresh or dried)
1 cinnamon stick (optional)
10 cloves (optional)
¾ cup sugar or honey (for fermentation)
Equipment
Quart mason jar
Fermentation airlock (optional)
Fine mesh sieve
Large pot
1-gallon glass jar
Cheesecloth
Rubber band
Flip-top bottles
Step 1: Make a Wild Elderberry Starter
This is where the fermentation begins.
Combine elderberries, sugar, and water in a quart-sized jar.
Cover with a cloth or airlock and secure it.
Stir once per day.
After 4–5 days, you should see bubbling activity.
Strain out the elderberries once the starter is active.
Step 2: Make the Elderberry Soda
Set your active starter aside.
In a large jar, combine water, elderberries, ginger, and spices.
Stir in the sugar or honey.
Add the strained elderberry starter (or use a ginger bug as an alternative).
Cover with cheesecloth and ferment in a cool, dark place.
Stir daily and watch for active fermentation within 1–2 days.
After 5–7 days, strain and transfer to flip-top bottles.
Let bottles sit at room temperature for 1–2 days to build carbonation.
Refrigerate once fizzy.
Why This Recipe Works
This recipe uses wild fermentation, which means you’re relying on naturally occurring yeast instead of a controlled starter like a ginger bug.
That gives you:
A more complex flavor
A slightly tangy finish
Natural carbonation
It’s a slower process, but the result is something you really can’t replicate with a quick mix.
Tips for the Best Fermented Soda
Use non-chlorinated water to support fermentation
Make sure your starter is visibly active before using it
Stir daily to keep fermentation moving
Don’t rush bottling — early bottling can cause pressure issues
Always refrigerate once carbonation develops
Wild Starter vs Ginger Bug (Which Should You Use?)
This recipe gives you two options:
Wild Elderberry Starter → more traditional, deeper flavor
Ginger Bug → more consistent, slightly easier
If you’re new to fermentation, the ginger bug can feel more predictable.If you want to experiment, the wild starter is a great place to start.
Is Wild Fermented Elderberry Soda Good for You?
Because it’s naturally fermented, it contains beneficial bacteria along with the natural compounds found in elderberries and ginger.
It’s a more natural option compared to most processed sodas.
How Is This Different From Other Elderberry Drinks?
This sits on the more advanced end of your “elderberry drink spectrum”:
Sparkler → quick, no fermentation
Ginger bug soda → controlled fermentation
Wild fermented soda → natural, wild fermentation
Each has its place — this one just leans more into the traditional process.
Storage & Safety Tips
Store finished soda in the refrigerator
Best enjoyed within 1–2 weeks
Always monitor carbonation levels
Be cautious of pressure buildup before opening
Fermentation is simple, but it does require attention — especially when bottling.
Can You Make This Without a Wild Starter?
Yes.
If you prefer:
Use a ginger bug instead
Or make a quick version with sparkling water and syrup
But the wild starter is what gives this recipe its unique character.
More Ways to Use Elderberries
If you enjoy this, you can use elderberries in a lot of different ways:
Make elderberry syrup
Brew elderberry tea
Add to smoothies or drinks
Use in other fermented recipes
Once you start experimenting, there’s a lot you can do with them.
FAQs About Wild Fermented Elderberry Soda
How long does wild fermented elderberry soda take?
The full process usually takes about 5–7 days for fermentation, plus 1–2 days for carbonation in bottles.
Why isn’t my fermentation active?
If you’re not seeing bubbles:
Your environment may be too cold
The starter may not be active yet
There may not be enough sugar
Give it more time and make sure conditions are right.
Is wild fermented soda alcoholic?
It’s typically very low in alcohol, especially with shorter fermentation times. However, longer fermentation can slightly increase alcohol content.
Can I use a ginger bug instead?
Yes, and it’s often more predictable. The wild starter just gives a different flavor and fermentation style.
How do I know when it’s ready?
You’ll notice:
Visible bubbles
Slight fizz
A tangy flavor
That’s when it’s ready to bottle and refrigerate.
Can kids drink this?
Many families do, since it’s low in alcohol and made with simple ingredients. If you prefer, you can always use a non-fermented version instead.
