Homemade Raspberry Lemon Probiotic Soda

Raspberry Lemon Probiotic Soda

Summery, fruity, and naturally fizzy, this Raspberry Lemon Probiotic Soda is a refreshing homemade fermented drink made with raspberries, fresh lemon juice, honey, and an active ginger bug starter.

If you’ve been wanting to make your own probiotic-style soda at home, this is such a fun recipe to try. The raspberry lemon juice gives the soda a pretty pink color and a fresh tart flavor, while the ginger bug helps naturally carbonate the drink during fermentation.

What Is a Ginger Bug?

A ginger bug is a fermented starter made with fresh ginger, sugar, and water. Once it becomes active and bubbly, it can be used to naturally carbonate homemade sodas.

Think of it as a starter culture for fizzy fermented drinks. Instead of using commercial carbonation, the ginger bug helps create bubbles through fermentation. Need to make a ginger bug first? Follow our full ginger bug recipe here.

Why You’ll Love This Recipe

This homemade soda is:

• Bright and refreshing

• Made with simple ingredients
  

• Perfect for summer sipping

• Easy to customize with different fruit flavors

Ingredients

Makes 1 bottle (about 16 oz / 500 ml)

For the raspberry lemon juice

• 1/2 cup raspberries, fresh or thawed frozen

• Juice from 1/2 lemon

• 1–2 teaspoons honey

• 1/2 cup water

For the soda

• Raspberry lemon juice from above

• 1/4 cup active ginger bug liquid, strained

• Filtered water, to top off the bottle

Instructions

1. Make the raspberry lemon juice

Add the raspberries, lemon juice, and 1/2 cup water to a blender. Blend until smooth.

Strain the mixture through a fine mesh strainer or cheesecloth to remove the raspberry seeds and add honey. 

2. Bottle the soda (we like to use the Smart Funnel for this step)

Pour the strained raspberry lemon juice into a clean fermentation-safe bottle.

Add 1/4 cup strained active ginger bug liquid.

Top off the bottle with filtered water, leaving 1–2 inches of headspace at the top.

3. Ferment

Seal the bottle and let it ferment at room temperature for 1–3 days, or until fizzy.

Check and burp the bottle daily. Fruit-based sodas can carbonate quickly, especially in warm kitchens.

4. Chill before opening

Once the soda is fizzy, transfer the bottle to the fridge and chill well before opening.

Open carefully, preferably over the sink, as naturally fermented sodas can build pressure.

5. Serve

Serve chilled over ice with fresh raspberries, lemon slices, or mint, if desired.

Tips for Success

-Use an active ginger bug. Your ginger bug should be bubbly and active before using it to make soda.

-Leave headspace. Do not fill the bottle all the way to the top. Leave 1–2 inches of space for carbonation.

-Use fermentation-safe bottles. Naturally carbonated drinks build pressure, so use bottles designed to handle carbonation.

-Chill before opening. Cold temperatures help calm the carbonation and make the soda easier to open.

-Taste and adjust. For a sweeter soda, use 2 teaspoons honey. For a more tart soda, use less honey or add a little extra lemon.

Final Thoughts

This Raspberry Lemon Ginger Bug Soda is a simple and refreshing way to use your ginger bug once it’s active. It’s fruity, fizzy, and fun to make at home with just a few ingredients.

Once you try this version, you can experiment with other fruit combinations like strawberry lime, peach orange, blueberry lemon, or watermelon mint.

Enjoy!!
