Preparation Steps

  1. 1

    Mix the Base Ingredients

    In a large mixing bowl, combine the carbonated water and the diet sweetener. Stir gently to dissolve the sweetener completely without losing too much carbonation.

  2. 2

    Add Flavorings

    Slowly add the natural flavors, phosphoric acid, and citric acid to the mixture. Stir carefully to ensure even distribution of flavors.

  3. 3

    Incorporate Caffeine (if using)

    If you want to add caffeine, mix it into the drink at this stage, ensuring it is well combined.

  4. 4

    Add Food Coloring

    Finally, add the food coloring, stirring gently until the mixture achieves a uniform color resembling Diet Dr Pepper.

  5. 5

    Chill and Serve

    Transfer the mixture to a bottle or pitcher and refrigerate for at least 30 minutes before serving. Serve chilled over ice or in a glass.
