Welcome to the world of fermentation!
Where science meets simplicity, and your gut gets all the glory. There’s something magical about cracking open a bottle and hearing that satisfying fizz—but what if that bubbly refreshment wasn’t just tasty, but good for you, too?
Fermentation might sound like the realm of hardcore homesteaders or lab-coated scientists, but don’t be fooled: making your own probiotic sodas is delightfully low-effort, wildly rewarding, and surprisingly fun. With just a few minutes of hands-on time and some basic ingredients, you can start transforming simple sugars and fruits into vibrant, living drinks that bubble with flavor and beneficial bacteria.
It’s DIY with a delicious twist—no fancy gear, no complicated steps, just the pure satisfaction of creating something fizzy, healthy, and entirely your own. Ready to turn your kitchen into a tiny fermentation lab? Let’s get to know the basics.
What’s a Ginger Bug, and What is it Used for?
Think of a ginger bug as your homemade soda starter—a natural culture made from fresh ginger, sugar, and water that captures wild yeasts and beneficial bacteria from the environment (and the ginger itself). In just a few days, this simple mixture starts to bubble and ferment, becoming the magical ingredient that turns sweet liquid into fizzy, probiotic soda. Don’t worry I walk you through exactly how to do this!
Once you make it, using it is easy: once your ginger bug is nice and active (you’ll see bubbles and a slight tangy smell), you just strain a small amount into your fruit or juice base. Seal it in a bottle, let it sit at room temperature for a couple of days, and voilà—you’ve got naturally carbonated soda full of gut-friendly microbes.
The best part? A ginger bug is endlessly reusable. Feed it a little more ginger and sugar regularly, and it keeps going like a bubbly pet for your kitchen. It’s an easy, affordable way to jump-start fermentation without relying on store-bought cultures—just good old-fashioned nature doing its thing.
If this sounds fun and easy to try (because it is)…
Let’s get to brewing!

Homemade Probiotic Sodas
Equipment
- 1 large wide mouth mason jar for fermenting – 64oz
- 4-6 small flip top bottles – 8oz each
- 1 fermenting mason jar for ginger bug – 16oz
- 1 parchment paper or dish towel
- 1 rubberband
Ingredients
For the Ginger Bug
- 6 tbsp raw organic ginger (divided)
- 6 tbsp white sugar (divided)
- 2 cups filtered water (divided)
For the Probiotic Soda
- ½ cup active ginger bug – instructions below
- 3-4 cups filtered water
- 3 cups juice – fresh pressed, store-bought, or raw juicy produce like berries
Instructions
STEP ONE: Make a Ginger Bug Starter (about a 4-5 day process that takes just 2 min / day)
DAY 1:
- grab your 16oz mason jar and add 1 cup of filtered water
- add 3tbsp of sugar to filtered water
- Wash and chop 3tbsp worth of your raw organic ginger (keep skin on!) into small bites, add to water/sugar mixture
- stir vigorously for 1 minutes to help dissolve the sugar and evenly distribute the ingredients
- Cover mason jar with parchment paper and wrap with a rubber band (you can also just place the flat metal lid but do not seal with screw top!)
- At least once or twice throughout the day give the ginger bug a swirl/stir to mix up the sugars and encourage activation
DAY 2-5:
- Feed your ginger bug around the same time every day by adding 1tbsp of sugar and 1tbsp of freshly chopped ginger. Mix vigorously and swirl/stir at least once later in the day.
- Each day you should start to see your ginger bug get a little cloudy and a foamy layer of bubbles start to form on the top. Once there is a thin, full layer of bubbles (usually between day 4 and 5) your ginger bug is considered "active" and can be used as a starter culture to ferment juice/fruit into a probiotic soda!
- see note section for how to care for your ginger bug starter ongoing!
STEP TWO: Ferment Soda (about a 2-4 day process and very dependent on the type of juice / fruit you use as how active your starter is) There is no daily maintenance:)
DAY 1:
- To your large 64oz airtight mason jar add 3 cups of juice (I prefer fresh cold pressed but store-bought works too!), 3 cups of filtered water and 1/2 cup of strained active ginger bug (use a fine mesh strainer). Liquid should be 2 inches from the top so add additional water if necessary. Mix everything until well combined, close airtight lid, store in dark neutral climate for 24hrs.Some people prefer a lose lid again like the ginger bug for this stage of fermentation, but I've personally found more success with an airtight flip top lid – you can play around with what works for you!my favorite combos have been: strawberries, raspberries, honeydew, pineapple, oranges. Flavorful high sugar fruit will be best because this is what gives the ginger bug food to eat and produce microbes/carbon dioxide!
DAY 2:
- After 24hrs "burp" your soda by carefully opening the lid and letting any carbon dioxide built up escape so that your bottles doesn't explode:) There may be no bubbles/air to release or you may have tons of bubbles! It really just depends on the health of your ginger bug, type of juice you used and temp of your house. Don't mix/shake your mixture, it may disrupt the fermentation process.
- Close it up and place back on shelf if there are no bubbles, or if it's already really bubbly you can move to step 3 already!
DAY 3:
- before burping your bottle, assess any bubbles forming on the top layer of the soda (even the tiniest bit of bubbles around the rim is a sign that fermentation is working!) Burp and place back on shelf. Or if it's really bubbly you can move to step 3 already!
DAY 4:
- At this point you should have bubbles on the top (even little ones, it may not be as foamy and bubbly as your ginger bug!) and there may be some white sediment on the bottom of the jar. Do not stir! If you have NO bubbles, don't deem this as a fail! I've had some recipes not produce bubbles but once I bottle them to further carbonate, they still end up fizzy! Every recipe will be different and each fruit reacts differently to the ginger bug. You can go one more day to see if bubbles form but in my opinion day 4 is a good time to bottle so you don't begin creating an alcohol content above 1%
STEP 3: Bottle Soda (this is a 2-3 day process with no daily maintenance)
- If you used raw cold pressed juice, you may have some pulp on the bottom of your large fermenting jar. I would strain all of the liquid into a large pourable measuring cup with a fine mesh strainer so you have a clear liquid that can easily funnel into small flip top bottles
- Slowly divide strained mixture into 4-6 8oz flip top soda bottles with a funnel and close completely
- Let these bottles sit on the shelf for an additional 24hrs if you want to further ferment, This might increase alcohol content and may give a more tangy flavor – which can be yummy! Just up to whatever your tastebuds prefer.
- Otherwise your fermenting is done and you can now build up carbonation in the fridge! Place bottle in the fridge for 2-3 days and then enjoy over ice! I typically give mine a little shake before pouring to activate the bubbles, but this all depends on how bubbly your soda was during fermentation – be careful not to explode them!
- Consume within 1 month for optimal carbonation and flavor but these can be good for up to 3 months! Use your best judgement on smell and flavor to determine if they are still good
