Ingredients
- 2½ cups chopped fresh rhubarb (about 3–4 stalks) – Look for vibrant pink stalks for the best flavor and color.
- 4 cups water – Filtered water is best for the purest taste.
- 2–4 tablespoons honey, maple syrup, or sugar – Adjust to your preferred sweetness level. I love the subtle floral notes of honey!
- 1 tablespoon lemon juice (optional) – Adds a lovely brightness and balances the sweetness.
- Ice cubes – Plenty of them for a truly refreshing drink!
- Mint leaves or lemon slices, for garnish – For a pretty presentation and an extra pop of flavor.
How to Make It
- Combine rhubarb and water in a saucepan. Bring to a boil, then reduce heat and simmer for 15–20 minutes, or until rhubarb is soft and the liquid is a beautiful pink. This is where the magic happens!
- Strain the mixture through a fine-mesh strainer, pressing on the solids to extract all that delicious rhubarb flavor. You can discard the pulp or, if you’re feeling adventurous, save it for a homemade jam!
- Stir in your chosen sweetener and lemon juice (if using) while the tea is still warm. The warmth helps the sweetener dissolve completely.
- Cool the tea to room temperature, then refrigerate for at least 1 hour to allow the flavors to meld. Patience, my friend, is key here!
- Serve chilled over ice. Garnish with fresh mint leaves or lemon slices for an extra touch of elegance.

Substitutions & Additions
Feel free to experiment! Instead of rhubarb, try using strawberries, raspberries, or even peaches for a different fruity twist. For a more spiced-up version, add a cinnamon stick while simmering. You could also add a splash of sparkling water for extra fizz.
Tips for Success
- Don’t overcook the rhubarb; it can become mushy. Aim for tender but still slightly firm pieces.
- If you’re making this ahead of time, store the cooled tea in an airtight container in the refrigerator for up to 3 days.
- Taste and adjust sweetness as needed. Sweetness preferences vary!
How to Store It
Store leftover iced rhubarb tea in an airtight container in the refrigerator for up to 3 days. The flavors will actually deepen slightly over time!
FAQs
- Can I use frozen rhubarb? Yes! Just thaw it completely before using.
- Can I make this in a slow cooker? Absolutely! Combine ingredients in your slow cooker and cook on low for 4-6 hours.
- What if I don’t have a fine-mesh strainer? A regular strainer will work, but you might end up with a few more bits of rhubarb in your drink.
- Is this recipe vegan? Yes, it is, as long as you use a vegan sweetener like maple syrup or agave.
