In a measuring pitcher combine 0.5 cups fresh lemon juice, 0.5 cups fresh orange juice and 0.5 cups simple syrup. Stir briskly until fully combined. This creates a balanced citrus base that will marry with the sodas. Adjust sweetness with additional simple syrup to taste.

Assembly

Prepare glasses

Fill four highball or Collins glasses with ice cubes (about 6 per glass). Add one lemon wheel and one orange wheel to each glass and gently press them against the inside of the glass.

Combine base and sodas

Divide the citrus base evenly between the four glasses (about 3 tablespoons / 22 ml per glass). Then top each glass with a layered combination: pour 125 ml chinotto, 62.5 ml aranciata, 62.5 ml aranciata rossa, and 62.5 ml limonata into each glass. Pour gently over the back of a spoon or down the side of the glass to reduce foaming and preserve some layering for visual appeal.

Finish and garnish

Give each drink a light stir (1–2 gentle turns) to incorporate the soda and citrus base without losing too much carbonation. Garnish each glass with a sprig of fresh mint tucked beside the fruit wheels. Serve immediately with a straw.
