Step‑by‑Step Instructions for Rhubarb Mocktail
Step 1: Prepare the Rhubarb
Start by washing and dicing about 2 cups of rhubarb into small pieces, roughly 1 cm in size. This ensures quick cooking and easy breakdown of the rhubarb during the syrup-making process. Set the diced rhubarb aside as you gather the rest of your ingredients, including honey, basil, and water.
Step 2: Cook the Syrup
In a medium saucepan, combine the diced rhubarb, ½ cup of honey, 2 cups of still water, and a handful of fresh basil leaves. Place the saucepan over medium heat and bring the mixture to a rolling boil. Once boiling, reduce the heat to low and let it simmer for about 12 minutes. You’ll notice the rhubarb breaking down and the mixture thickening slightly.
Step 3: Cool the Mixture
After simmering, remove the saucepan from the heat and allow the rhubarb mixture to cool for about 10-15 minutes. As it cools, the flavors will meld beautifully, creating a rich syrup that balances the tartness of the rhubarb with the sweetness of honey. Make sure it’s not too hot before proceeding to the next step.
Step 4: Strain the Syrup
Once cooled, take a fine mesh sieve and place it over a large bowl. Carefully pour the rhubarb mixture through the sieve, allowing the syrup to collect in the bowl while discarding the solids. Use a spoon to press down gently on the solids to extract as much syrup as possible, leaving you with a vibrant, smooth rhubarb syrup.
Step 5: Assemble the Mocktail
For serving, fill each glass with about ½ inch of the freshly made rhubarb syrup. Next, add a handful of ice cubes to each glass, ensuring they chill the syrup perfectly. Then, top off each glass with sparkling water, giving it a gentle stir to mix everything together. The result will be a delightful Rhubarb Mocktail that’s as refreshing as it is beautiful.

Make Ahead Options
These Rhubarb Mocktail preparations are fantastic for busy cooks! You can make the rhubarb syrup up to 3 days in advance by following these simple steps. Start by cooking the diced rhubarb, honey, and water until it thickens into syrup, then strain it and allow it to cool completely. Once cooled, transfer the syrup into an airtight container and refrigerate it. This will keep the flavors vibrant and the consistency just perfect for your mocktail. When you’re ready to serve, simply fill your glasses with about ½ inch of syrup, add ice, and top with sparkling water. Your refreshing drink is now just a few moments away, ready to impress your guests!
How to Store and Freeze Rhubarb Mocktail
- Fridge: Store any leftover rhubarb syrup in an airtight container in the fridge for up to a week. This way, you can easily refresh your mocktail on demand!
- Freezer: If you want to prepare ahead, freeze the rhubarb syrup in ice cube trays. Transfer the cubes to a freezer-safe bag for up to 3 months of delightful summer sips on standby.
- Reheating: When you’re ready to use frozen syrup cubes, simply thaw them in the fridge overnight or let them sit at room temperature for a few hours before mixing with sparkling water.
- Serving Suggestion: Always taste your syrup before serving it in a mocktail. If flavor has dulled while stored, consider adding a touch of fresh basil for a burst of freshness!

Expert Tips for the Best Rhubarb Mocktail

- Basil Substitute: If you don’t have basil, feel free to replace it with rosemary for a different yet delightful flavor twist in your Rhubarb Mocktail.
- Chill Effectively: For the best experience, serve the mocktail with plenty of ice cubes, which will maintain its refreshing chill on warm days.

Rhubarb Mocktail Recipe FAQs
What should I look for when selecting rhubarb?
Absolutely! When choosing rhubarb, you want to look for firm stalks that are vibrant and crisp. The color can vary from pale green to deep red, but avoid any stalks that show dark spots or are limp and wilted. Fresh rhubarb typically has a slightly tart and tangy scent.
How long can I store the rhubarb syrup in the fridge?
You can store leftover rhubarb syrup in an airtight container in the refrigerator for up to one week. Just remember to give the syrup a gentle stir before serving, as it may separate over time.
Can I freeze rhubarb syrup?
Yes, you can! To freeze your rhubarb syrup, pour it into ice cube trays and freeze until solid—this usually takes about 3 to 4 hours. Once frozen, pop the cubes into a freezer-safe bag. The rhubarb syrup cubes can be kept in the freezer for up to 3 months. When you want to use them, simply thaw the cubes in the fridge overnight or let them sit at room temperature.
What if my rhubarb syrup ends up too sour?
Very good question! If your syrup turns out too sour, you can simply add more honey to balance the flavors. Start by whisking in a tablespoon of honey at a time, tasting as you go until it reaches your desired sweetness. Additionally, if the syrup isn’t thick enough, simmer it a bit longer to allow it to reduce and become syrupy.
Are there any allergy concerns with this rhubarb mocktail?
Yes, it’s always important to consider allergies! While rhubarb is generally safe, individuals with allergies to plants in the buckwheat family should avoid consuming it. Additionally, if you’re substituting honey for agave syrup for a vegan option, ensure that your guests do not have any agave-related allergies. Always double-check with your guests to ensure everyone can enjoy this delightful drink!
