Two Approaches: Syrup Method vs. Direct Method
Syrup method (recommended): Make a lemon simple syrup, then combine with plain sparkling water at serve time. More control over carbonation level. Better for batches and entertaining.
Direct method: Mix fresh lemon juice and sugar directly into a bottle and carbonate. Simpler, but carbonating juice can be tricky (more foam, less predictable).
Syrup Method — Ingredients (makes ~500ml syrup / 4–5 servings)
- 200ml (¾ cup + 2 tbsp) fresh lemon juice (about 6–7 lemons)
- Zest of 4 lemons
- 300g (1½ cups) white sugar
- 200ml (¾ cup) water
- ½ tsp citric acid (amplifies lemon brightness)
- Pinch of sea salt
- Combine lemon zest, sugar, and water. Simmer gently 3 minutes until sugar fully dissolves. Remove from heat.
- Cool to room temperature, then add lemon juice, citric acid, and salt. Stir well.
- Strain through fine mesh. Bottle and refrigerate. Keeps 2–3 weeks.
Serving
Fill a glass with ice. Add 60–80ml lemon syrup. Pour 200–250ml cold sparkling water gently over it. Stir once. Adjust ratio to preference — this is intentionally tart and bright. Add more syrup for sweeter, more water for lighter.
For a 1-liter pitcher: combine 200ml syrup with 800ml cold sparkling water. Serve immediately over ice — carbonation dissipates in a pitcher within 10–15 minutes.
Variations
- Strawberry Lemonade: Add 100g macerated fresh strawberries to the syrup during the cool-down steep, then strain
- Mint Lemonade: Add 20g fresh mint leaves to steep for 10 minutes off heat, then strain
- Meyer Lemon: Substitute Meyer lemons for a sweeter, more floral character — reduce citric acid by half
- Honey Lemonade: Replace sugar with equal weight of honey for a more complex sweetness
