Add sugar and water into a small saucepan over medium heat and bring just to a bowl then reduce to a simmer. Stir until the sugar dissolves in the water to create a simple sugar syrup. Remove from the heat and cool to room temperature.

Add the diced peaches to a blender or food processor and puree until smooth.

Combine the cooled sugar syrup, peach puree, water and lemon juice in a large pitcher or container and stir well to combine.

Adjust water and lemon juice to taste.

Chill in the refrigerator until ready to serve or pour over ice and serve immediately, enjoy!
