This non-alcoholic peach bellini uses real peach puree, no fake syrups, and sparkling water that actually holds bubbles. The technique -- frozen peach chunks instead of fresh puree -- is what keeps it cold and fizzy without diluting.
Add frozen peach chunks to a blender. Blend until completely smooth. Using frozen peaches instead of fresh puree keeps the drink cold without diluting it with ice. The texture should be smooth and pourable -- if it's too thick, add 1 to 2 tablespoons of cold water.
Add lemon juice and simple syrup (if using) to the blended peach. Blend briefly to combine. Taste -- the peach puree should be slightly sweeter than you want the finished drink since the sparkling water will dilute it.
For a smoother bellini, press the puree through a fine mesh strainer. Skip this step if you prefer a more textured, fresh-fruit feel.
Assemble
Spoon 3 to 4 tablespoons of peach puree into each chilled glass.
Pour cold sparkling water slowly over the back of a spoon held just above the puree. This float technique preserves the two-layer look (pink puree at the bottom, clear fizz above) and keeps the carbonation alive. Fill each glass to the top.
Stir once gently at the table and serve right away. The bellini is best in the first 3 minutes before the puree fully incorporates and the bubbles settle.
Notes
Frozen peaches work better than fresh -- they blend smoother and keep the drink colder without ice dilution.For a batch: make the puree in advance and refrigerate. Add sparkling water per-glass at serving time only -- never pre-mix the full batch.Non-alcoholic sparkling wine (like Leitz Eins Zwei Zero) works in place of sparkling water for a more authentic taste.
