🥣Equipment
For this recipe you just a few basic tools to get the job done:
- Measuring cups and spoons: Accurate measurements are key!
- Medium pot: For simmering the plums and cinnamon to bring out their flavors.
- Cooking Spoon: Use a heat-resistant spoon like wood, plastic or silicone. Ideal for mashing the plums and stirring the mixture as it cooks. An optional potato masher can help squeezing out all the juices from the plums.
- Strainer: To separate the solids from the liquid.
- Fermentation bottle: A glass bottle with a tight seal is perfect for fermenting the soda.
📝The Ingredients
This soda uses simple ingredients, but each one plays an important role in balancing flavor and fermentation:
- Water: The base for creating the plum syrup.
- Plums: Use fresh, ripe plums for the best flavor and sweetness.
- Cinnamon: A cinnamon stick works best, but ground cinnamon is a fine alternative.
- Sugar: Essential for feeding the ginger bug during fermentation of the soda to make it bubbly.
- Alternative Sugar: Use an alternative sweetener like stevia, monk fruit sweetener, or erythritol to adjust the sweetness. Normal white sugar will be "eaten" by the ginger which makes the soda bubbly.
- Ginger Bug: The fermentation starter that gives the soda its natural fizz.

🍴Serving suggestions
This Cinnamon Plum Soda is as versatile as it is refreshing. Whether you’re enjoying it solo or serving it up for guests, here are a few ways to enjoy it:
- Serve over ice: This soda is best served chilled, but pouring it over a glass of ice really makes those fruity and spiced flavors pop.
- Garnish: Add a cinnamon stick or plum slice for a beautiful, seasonal touch.
- Lighten with sparkling water: For a lighter, more subtle fizz, top your soda with a splash of sparkling or flat water. This is a great option if you like your drinks a bit milder.
- Make a cocktail: Mix with vodka, gin, or rum for a delicious fall-inspired drink.
- Pair with fall treats: This soda goes perfectly with cinnamon rolls, pumpkin bread, or a slice of apple pie!
- Pair it with sweet treats: Serve this alongside your favorite fall desserts like cinnamon rolls, apple pie toaster strudel, or pumpkin bread. The flavors complement each other perfectly, making it an ideal autumn gathering drink.
- Make it a cocktail: If you’re looking to make this soda a bit more grown-up, try mixing it with vodka, gin, or rum. The fruity and spiced notes pair beautifully with a range of spirits.
🥄Storage
Once your soda has fermented to your liking, it’s important to store it properly to maintain its freshness and carbonation:
- Refrigerate: After the 2-3 day fermentation, transfer the bottle to the fridge. This slows down the fermentation process and preserves the soda’s fizz.
- Shelf life: The soda stays fresh for about 1-2 weeks in the fridge. After that, it will continue to ferment, causing the sweetness to decrease and the flavor to change. So, you can still enjoy the drink but the flavor will change over time getting more sour the more it ferments.
- Release pressure: Be sure to "burp" the bottle daily (open it briefly to release excess gas) to avoid over-carbonation or potential explosions.

❗Troubleshooting
Here are some common issues you might run into when making fermented soda and how to fix them:
- Soda tastes sour: The longer it ferments, the less sweet and more tangy it gets. Refrigerate earlier to retain sweetness.
- Not fizzy enough: If your soda isn't carbonating, your ginger bug might not be active enough. Let it ferment longer, or try adding a bit more sugar to feed the yeast.
- Too fizzy or over-carbonated: This can happen if you ferment too long or forget to burp the bottle. Release pressure daily or refrigerate sooner.
