Sparkling Blueberry Lime Mocktail

This Sparkling Blueberry Lime Mocktail is built around a quick homemade blueberry syrup, brightened with a touch of fresh lime juice and topped generously with cold sparkling water. The result is a drink that's sweet and fruity up front, with a light citrus accent and plenty of fizz — closer to a fruity sparkler than a sour cocktail. It comes together in about 25 minutes, most of which is hands-off simmering and cooling, so it's an easy pick for beginners or for anyone who wants a homemade drink without much fuss.

Why This Recipe Works

Simmering the blueberries with honey and a splash of water breaks them down into a real fruit syrup, rather than relying on bottled juice or artificial flavoring.
Straining the syrup removes the skins, so the drink stays smooth and pourable instead of pulpy.
A generous pour of sparkling water relative to the syrup and lime keeps the drink light and bubbly instead of concentrated or heavy — the syrup carries most of the flavor, with lime as a light accent rather than a dominant sour note.

Serving and Storage Tips

The blueberry syrup is the only part that needs advance prep, and it can be made up to 5 days ahead and kept chilled, which makes this a convenient option for parties — just build the glasses to order. Serve it in a tall 12–14 oz (350–400 ml) glass over plenty of ice, garnished with a lime round, fresh mint, and a few whole blueberries for color.

A Note on Sparkling Water

Plain sparkling water lets the blueberry-lime flavor lead. An unsweetened berry-flavored sparkling water will make the drink more fruit-forward without adding significant sweetness, while a sweetened variety will make it noticeably sweeter — check the label, since flavored sparkling waters vary in whether they contain added sweeteners.

Description

A bright, bubbly mocktail made with a quick homemade blueberry syrup, a touch of fresh lime, and plenty of sparkling water. Sweet, lightly tart, and full of fizz, it's ready in about 25 minutes and easy to scale up for a crowd.

Ingredients

150 g / 1 cup Blueberries (Fresh or frozen)
42 g / 2 Tbsp Honey (Sub agave or maple syrup)
15 ml / 1 Tbsp Water (For the syrup)
40 ml / 3 tsp (1–2 limes) Fresh lime juice (Fresh is best)
1 g / 4 leaves Fresh mint (Add at serving)
300 ml / 10 fl oz Sparkling water (Plain or flavored; keep cold)
67 g / 1 whole Lime (Sliced, for garnish)
15 g / 1 Tbsp Blueberries (Extra, for garnish)

Instructions

1
Make the syrup: Add the blueberries, honey, and water to a small pot. Bring to a boil, then turn the heat down low. Simmer 5 minutes, mashing the berries a bit, until they burst and the syrup thickens slightly.
2
Strain and cool: Pour through a fine sieve into a bowl, pressing out all the liquid. Discard the skins. Set the bowl in a larger bowl of ice water and stir for 10 minutes until fully cooled.
3
Build the glasses: Fill 2 glasses with ice. Add 80 ml (5 Tbsp) syrup to each.
4
Add lime and soda: Pour in 20 ml (about 4 tsp) lime juice per glass. Top with 150 ml (5 fl oz) cold sparkling water. Stir once, gently.
5
Garnish and serve: Add blueberries, a lime slice, and mint to each glass. Serve right away.

Note

Storage: The blueberry syrup keeps in an airtight container in the refrigerator for up to 5 days. Do not store the assembled drink — the sparkling water will go flat.
Freezing: The syrup freezes well for up to 2 months; thaw in the refrigerator overnight before using.
Reheating: Not applicable — this is a cold drink; only the syrup component is heated during preparation.
Pro Tips:
- Use frozen blueberries for the syrup — they tend to release more juice and result in a deeper color.
- Cool the syrup fully (via the ice-bath method in Step 2) before building the drink, or it will melt your ice and dull the fizz.
- Add the sparkling water last and pour gently to preserve the carbonation.
- A tiny pinch of salt (about ⅛ tsp) stirred into the warm syrup can round out the blueberry flavor, though it's optional.
Scaling for a Crowd: To multiply this recipe, scale the blueberry syrup ingredients (blueberries, honey, water) by the number of servings needed, but keep the per-glass lime juice (20 ml) and sparkling water (150 ml) ratio the same — build each glass individually rather than batching the lime and sparkling water together, so the drink doesn't go flat before serving.
Common Mistakes: Using too much lime juice will make the drink taste sour rather than balanced — stick to the small amount specified. Skipping the straining step will leave berry skins floating in the finished drink. Building the drink with warm syrup will dilute it and flatten the sparkling water.
