Finding a sophisticated summer drink that isn't loaded with sticky, heavy syrups can feel like a chore. You want something more exciting than plain water, but light enough to keep you feeling fresh. This sparkling lemonade delivers a crisp, botanical fizz that tastes like a high-end spa treatment in a glass.

Why This Recipe Rocks
I know floral flavors can be intimidating—nobody wants to drink perfume! But when done right, this sugar free lavender lemonade recipe is an absolute game-changer for your drink rotation.
- Floral, Not Soapy: The secret is a precise, short steep time. You get the delicate aroma of fresh blooms without any bitter aftertaste.
- Instant Refreshment: The combination of tart fresh lemon and effervescent club soda makes this incredibly thirst-quenching. It wakes up your palate immediately.
- No Sticky Mess: Since we skip the simple syrup boiling process, cleanup is a breeze. You spend less time scrubbing pots and more time sipping on the porch.
Fresh Ingredients for a sophisticated Sip
The beauty of this sparkling keto lemonade (no sugar) lies in its simplicity. We rely on high-quality basics to do the heavy lifting. I always grab culinary-grade lavender—it makes a huge difference compared to the stuff meant for sachets!
Using liquid stevia allows the bright citrus notes to shine through without that gritty texture you sometimes get from granulated sweeteners in cold drinks. If you love experimenting with botanical flavors, you might also enjoy my Crisp Cucumber Basil Sparkler for another garden-inspired treat.
Tips for the Perfect Pour
Making this low carb lavender lemonade with stevia is easy, but a few small tweaks ensure it tastes professional every time.
- Don't Boil the Buds: Pour hot water over the lavender rather than boiling them together. This preserves the delicate essential oils and prevents bitterness.
- The Salt Secret: It sounds strange, but a tiny pinch of salt works magic on citrus. It suppresses the bitterness of the lemon pith and makes the sweetness pop.
- Fizz Control: Always add the club soda right before serving. Stir gently to keep those bubbles lively and crisp.
If you're hosting a brunch and want a variety of colorful drinks, try pairing this with a pitcher of Refreshing Hibiscus Lemonade. They look stunning together on a table!
Common Questions
Can I make this ahead of time?
Absolutely! You can make the lavender-lemon concentrate up to 3 days in advance and store it in the fridge. Just wait to add the ice and sparkling water until you are ready to serve so it stays carbonated.
What if I don't have liquid stevia?
No problem. You can substitute with a powdered erythritol or monk fruit blend. Just be sure to whisk it into the warm lavender tea so it dissolves completely before cooling.

Description
This refreshing beverage offers a sophisticated, floral twist on a backyard classic, perfect for warm afternoons or evening gatherings. By steeping the lavender for a shorter, precise window, the flavor remains light and aromatic without becoming bitter or soapy. It contains no added sugar and is low-carb, delivering a crisp, thirst-quenching experience without the heavy sweetness of traditional concentrates.
Ingredients
- 1 cup Water (for steeping) (240 ml)
- 2 Tbsp Dried culinary lavender buds
- 1 tiny pinch Fine sea salt (optional, helps pop the citrus flavor)
- ¾ cup Freshly squeezed lemon juice (from approx. 4–5 large lemons) (180 ml)
- ½ tsp Liquid stevia (plus more to taste, or substitute ⅓ cup powdered erythritol/monk fruit blend)
- 4 cups Club soda or sparkling water, well-chilled (950 ml)
- 2 cups Ice cubes (plus more for serving)
- Garnish: Fresh lemon wheels or fresh lavender sprigs
Instructions
- Steep the lavender: Bring the 1 cup of water to a boil in a small saucepan or kettle. Remove from heat. Place the 2 Tbsp dried lavender and pinch of salt in a heat-proof bowl or large glass jar. Pour the boiling water over the buds and let steep for 15 to 20 minutes (until the water turns a pale golden-purple and smells floral but not medicinal).
- Strain and sweeten: Pour the lavender tea through a fine-mesh sieve into a large pitcher to remove all flower buds. While the liquid is still warm, stir in the ½ tsp liquid stevia (or powdered sweetener) until fully dissolved.
- Add citrus base and cool: Stir the ¾ cup lemon juice into the sweetened lavender water. Let this concentrate cool on the counter for about 15 minutes (or place in the fridge) before proceeding, to prevent the ice from melting too quickly and diluting the flavor.
- Assemble: Once the base is cool, add the 2 cups of ice to the pitcher. Gently pour in the 4 cups chilled club soda to preserve the carbonation. Stir gently to combine.
- Serve: Pour into tall glasses over fresh ice. Garnish with a lemon wheel or a fresh lavender sprig for aroma.
Notes
- Allergy Alert: Lavender is part of the mint family. Ensure guests do not have specific floral allergies.
- Culinary Lavender: Ensure you buy “culinary grade” lavender. Lavender sold for potpourri or crafts may be treated with pesticides or perfumes not safe for consumption.
- Why it works:
- Short Steep Time: Reducing the steep time from hours to 20 minutes prevents the release of excess tannins, which can make lavender taste like soap.
- Salt: A tiny pinch of salt suppresses bitterness in the lemon pith and enhances the perception of sweetness.
- Key Success Warnings:
- Do not boil the buds: Pour hot water over the buds rather than boiling them in the water to preserve the delicate essential oils.
- Add soda last: If you add the club soda too early, the lemonade will go flat. Add it immediately before serving.
- Variation: For a “Pink Lemonade” effect, add 1-2 smashed raspberries to the steeping water, then strain them out.
