Combine peaches, lemon juice, 2 cups of cold water, and sugar in a blender and blend until smooth. Strain the mixture through a fine-mesh sieve into a large pitcher, pressing to extract all liquid, then discard the solids.

Add the remaining 2 cups of cold water to the pitcher, stir well, and refrigerate for at least 30 minutes to chill.

Gently muddle mint leaves in the bottom of your serving glasses, then pour chilled peach lemonade over the mint and stir to combine the flavors.

Garnish each glass with extra mint leaves and a peach slice for an aromatic and refreshing twist.

While making the lemonade, add ginger slices to the blender with the peaches and other ingredients, blending until smooth.

Strain the mixture as usual, ensuring no ginger pieces remain, which will infuse the lemonade with a subtle, spicy kick.

For a fizzy drink, fill glasses halfway with the prepared peach lemonade.

Top off each glass with sparkling water and stir gently to combine, creating a delightful effervescent beverage.
