Lightly sweet and gorgeously pink, homemade rhubarb soda is a refreshing drink that captures the best of spring in every glass. With just a few ingredients, you can turn tart rhubarb into an elegant, thirst-quenching beverage that’s both nostalgic and new. This recipe requires very little effort and transforms humble stalks into an irresistible syrup that you can mix and match to suit any crowd or occasion.
I first whipped up rhubarb soda to cool off after a long day of gardening. I was amazed at how quickly it disappeared from the table, and now it is my go-to drink for spring brunches. This simple syrup is the kind of thing you will want to keep on hand all season.
Ingredients
- Fresh or frozen rhubarb: Gives the soda its beautiful color and tart punch. Aim for stalks that are firm and bright pink for best flavor and vibrancy.
- Granulated sugar or favorite alternative sweetener: Adds sweetness and balances rhubarb’s tartness. Use organic sugar for cleaner taste or switch to honey for a floral note.
- Filtered water: Helps dissolve the sugar and extract the rhubarb flavor. Always start with cold, fresh water for clarity and clean taste.
- Chilled sparkling water: Provides effervescence. Look for high-quality sparkling water for a crisp finish and use it ice cold.
Step-by-Step Instructions
- Prepare the Rhubarb Syrup:
- Combine chopped rhubarb and sugar in a non-reactive pot and stir thoroughly. The sugar will help draw out the juices as the mixture heats up.
- Simmer the Mixture:
- Add filtered water and bring everything to a lively boil over medium-high heat. Once boiling, reduce the heat to low. Let the mixture bubble gently for about eight minutes, stirring occasionally, until the rhubarb breaks down and is completely soft. This step creates the syrup’s foundation and draws out all the flavor from the rhubarb.
- Strain the Syrup:
- Set a jelly bag, cheesecloth, or a fine-mesh strainer over a heatproof bowl. Carefully pour the hot mixture in and let it drain naturally. Press very gently with a spoon to extract as much liquid as possible, but do not mash or the syrup will become cloudy.
- Cool and Chill:
- Transfer the strained syrup to a jar or container. Let it cool to room temperature first, then cover and refrigerate until fully chilled. Cold syrup blends better with sparkling water and preserves freshness.
- Mix the Soda:
- Fill glasses with ice. Pour two parts chilled sparkling water and one part rhubarb syrup into each glass. Stir gently to combine so the bubbles remain lively.
- Serve Immediately:
- Enjoy your homemade rhubarb soda straight away for the most refreshing flavor. You can garnish with citrus slices or fresh mint for a festive touch.

Rhubarb has always been a special ingredient in my kitchen because it reminds me of my grandmother tending her old rhubarb patch. The scent of simmering syrup always brings back memories of sunny backyard afternoons and big family tables.
Storage tips
Always chill the rhubarb syrup in a sealed container in the fridge. It will keep for about two weeks. If you make a large batch, freeze some in ice cube trays for easy single servings or cocktails later. Avoid storing the finished soda with sparkling water as it loses fizz quickly—always make that fresh.
Ingredient substitutions
Try other natural sweeteners such as agave syrup, coconut sugar, or maple syrup if you want more nuanced sweetness. For extra flavor, add aromatics like a slice of ginger, stick of cinnamon, or vanilla while you simmer. If you only have frozen rhubarb, use directly from the freezer—do not thaw first.
Serving suggestions
Rhubarb soda makes an impressive brunch or party drink served with slices of orange or strawberries. For adults, it is a versatile cocktail mixer. Pair with gin, vodka, or a splash of prosecco for a special twist. Offer it in small glasses as a nonalcoholic aperitif or punch at summer gatherings.
Cultural historical context
Rhubarb drinks have a long history in both home kitchens and artisanal soda shops across northern Europe and North America. In Victorian times, homemade fruit syrups like this were a symbol of household pride and hospitality. With the resurgence of soda making at home, rhubarb remains a star in seasonal refreshers.

Enjoy rhubarb soda as a sweet, refreshing way to celebrate spring’s bounty and create lasting memories with loved ones.
