Blend the base
Put pineapple chunks, sliced ginger, maple syrup, and lime juice into the blender. Pulse until smooth. The ginger will add a spicy zip — don’t worry, it mellows a touch when you chill and dilute with sparkling water.
Strain for silkiness (optional but recommended)
Pour the blended mixture through a fine-mesh sieve into a pitcher or bowl, using a spatula to press through the juice. This step removes fibrous pulp and gives the drink a sleek, café-quality texture. If you like a bit more body, skip the sieve and call it “rustic.”
Assemble the sparklers
Fill two glasses with ice. Pour the strained pineapple-ginger liquid to about halfway. Top off each glass with cold sparkling water and gently stir once to combine. Garnish with mint leaves and a lime wheel.
Serve immediately
Enjoy that fizzy, bright sip right away. The bubbles taste best fresh; the mixture loses fizz if you pre-mix too far ahead.
