Full Ingredients
Blackberry-Lime Spritz Base (Makes 2 Drinks)
- 1 cup (140 g) fresh blackberries, rinsed and patted dry
- Finely grated zest of 1 medium lime (about 1 tsp loosely packed)
- 1/4 cup (60 ml) freshly squeezed lime juice (from about 2 medium limes)
- 2–3 tbsp (24–36 g) granulated sugar, to taste
- Pinch of fine sea salt (about 1/16 tsp; optional but recommended)
To Finish the Spritz
- 2 cups (480 ml) chilled sparkling water, unflavored
- 1–1 1/2 cups ice cubes (enough to fill two tall glasses)
Optional Garnishes
- Extra fresh blackberries
- Thin lime wheels or wedges
- Fresh mint sprigs
Step-by-Step Instructions
Step 1: Chill your glasses and prep the ingredients
Place two tall glasses in the fridge or freezer to chill while you prep the drink. Cold glasses help keep the spritz extra refreshing and maintain the bubbles longer.
Rinse the blackberries and gently pat them dry. Wash and dry the limes, then finely zest 1 lime using a microplane or fine grater, taking care to remove only the bright green outer layer and not the bitter white pith. Juice enough limes to get 1/4 cup (60 ml) of fresh lime juice; strain out any seeds.
Step 2: Muddle the blackberries, lime, and sugar
In a sturdy jar, cocktail shaker, or mixing glass, add the blackberries, lime zest, lime juice, sugar, and a small pinch of fine sea salt. Using a muddler or the end of a wooden spoon, press and twist firmly for 30–60 seconds. Your goal is to crush the berries thoroughly so they release as much deep purple juice as possible, while helping the sugar start to dissolve into the liquid.
You should end up with a vivid, pulpy mixture that smells intensely of lime and berries, with visible flecks of lime zest throughout.
Step 3: Taste and adjust the base
Give the blackberry-lime mixture a quick stir and taste a small spoonful. If it is too tart, add an extra teaspoon or two of sugar and muddle briefly to dissolve. If it feels too sweet or not bright enough, add a splash more lime juice.
This is the flavor backbone of your spritz, so aim for a bold sweet-tart taste. Once diluted with sparkling water and ice, the flavor will soften, so the base should taste slightly stronger than you want the final drink to be.
Step 4: Strain (optional) and divide between glasses
If you prefer a smoother soda with fewer seeds and less pulp, set a fine-mesh strainer over a measuring jug or bowl and pour the blackberry mixture through. Use the back of a spoon to press on the solids, extracting as much richly colored juice as you can. Discard the seeds and pulp left in the strainer.
If you like a more rustic texture with bits of berry and zest floating in the drink, you can skip the straining step. Either way, divide the blackberry-lime base evenly between your two chilled glasses.
Step 5: Add ice and sparkling water
Fill each glass with ice, leaving at least 2.5 cm (about 1 inch) of space at the top. Slowly pour about 1 cup (240 ml) of chilled sparkling water into each glass. Pouring gently along the side of the glass helps preserve more fizz.
Use a long spoon to give each drink one or two slow stirs from the bottom up. You want to marble the dark blackberry concentrate through the clear sparkling water, creating a gorgeous gradient of purple and pink without completely knocking the bubbles out.
Step 6: Garnish and serve immediately
Top each spritz with a few whole blackberries, a lime wheel or wedge on the rim, and a small sprig of fresh mint if you are using it. The garnishes add color, fragrance, and a little extra wow factor.
Serve the blackberry-lime spritz right away while it is icy cold and lively with bubbles. Offer straws or long spoons if you left some berry pulp in the drink so people can enjoy the fruit at the bottom of the glass.
Pro Tips
- Use very cold ingredients. Chill the sparkling water, berries, and glasses beforehand to maximize fizz and freshness.
- Muddle, do not blend. Muddling keeps the drink vibrant and juicy without turning it into a smoothie-like puree.
- Adjust sweetness to your berries. Very ripe blackberries need less sugar; tart or out-of-season berries may need a bit more.
- Salt makes flavors pop. A tiny pinch of fine sea salt will not make the drink salty, but it sharpens the fruit and citrus flavors noticeably.
- Pour sparkling water gently. Fast pouring knocks out carbonation; slow pouring keeps the spritz lively and refreshing.
Variations
- Herb-infused spritz: Add a few fresh mint, basil, or rosemary leaves to the jar and muddle them with the berries and lime for an aromatic twist.
- Honey or agave version: Replace the granulated sugar with 2–3 tbsp (30–45 ml) liquid honey or agave syrup. Stir very well after muddling to ensure it dissolves into the juices before adding sparkling water.
- Grown-up spritz (21+ only): For an adult variation, add 1–1 1/2 oz (30–45 ml) of vodka, gin, or white rum to each glass before topping with sparkling water. Drink responsibly.
Storage & Make-Ahead
For the best fizz and texture, assemble the full spritz just before serving. However, you can prepare the blackberry-lime base (through the muddling and optional straining step) up to 24 hours ahead. Store it covered in the refrigerator. When ready to serve, briefly stir the base, divide it between glasses with ice, and top with freshly opened, chilled sparkling water. Once combined with sparkling water and ice, the drink is best enjoyed within 15–20 minutes, as the bubbles will gradually fade and the ice will dilute the flavors.
