I love making this rhubarb soda when I want something refreshing, lightly tart, and naturally sweet. The bright pink color makes it feel extra special, and the homemade rhubarb syrup gives it a fresh flavor that I can’t get from store-bought sodas. I usually serve it over ice on warm afternoons or during family gatherings because it always feels crisp and satisfying.
Why You’ll Love This Recipe
I enjoy this recipe because it uses simple ingredients and comes together without much effort. The rhubarb creates a tangy flavor that balances perfectly with the sweetness of the syrup and the sparkle from the soda water. I also like that I can adjust the sweetness depending on my taste. It feels fancy enough for guests but easy enough for everyday use.
Ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
4 cups chopped fresh rhubarb
1 cup granulated sugar
3 cups water
1 tablespoon fresh lemon juice
3 cups chilled sparkling water or club soda
Ice cubes for serving
Lemon slices or fresh mint for garnish (optional)
Directions
I place the chopped rhubarb, sugar, and water into a medium saucepan over medium heat.
I stir everything together and let it simmer for about 15–20 minutes until the rhubarb becomes soft and breaks apart.
I remove the saucepan from the heat and let the mixture cool slightly.
I strain the liquid through a fine mesh sieve into a bowl or pitcher, pressing gently to extract all the syrup. I discard the solids afterward.
I stir in the fresh lemon juice and chill the syrup in the refrigerator until cold.
When I’m ready to serve, I fill glasses with ice and pour about 1/3 cup of rhubarb syrup into each glass.
I top each glass with sparkling water and stir gently.
I garnish with lemon slices or mint if I want an extra fresh touch.

Variations
I sometimes add sliced strawberries while cooking the rhubarb for a sweeter fruit flavor. When I want a stronger citrus taste, I mix in lime juice instead of lemon. For a herbal twist, I like adding a few basil leaves or fresh ginger slices to the syrup while it simmers. I also enjoy using flavored sparkling water for a slightly different finish.
storage/reheating
I store the rhubarb syrup in an airtight container in the refrigerator for up to one week. I keep the sparkling water separate so the soda stays fizzy when served. If I want to make the syrup ahead of time, I sometimes freeze it in small portions for up to three months. I do not reheat the prepared soda, but I can gently warm the syrup if needed before chilling again.
FAQs
Can I use frozen rhubarb?
I can absolutely use frozen rhubarb in this recipe. I usually add it directly to the saucepan without thawing first.
Is this soda very sweet?
I find the sweetness balanced, but I can reduce or increase the sugar depending on my preference.
Can I make this recipe ahead of time?
I often prepare the syrup a day or two ahead and keep it chilled until serving time.
What can I use instead of sparkling water?
I sometimes use tonic water, lemon-lime soda, or plain carbonated mineral water for a different flavor.
Conclusion
I enjoy how fresh and vibrant this rhubarb soda tastes, especially during warmer months. The homemade syrup creates a unique flavor that feels both nostalgic and refreshing. Since it is easy to customize and simple to prepare, I always find myself making it again whenever rhubarb is in season.
