Sweetness activates pleasure centers in the brain, making coffee more enjoyable for many. Sonic uses syrups to:

  • Encouraging customers to tweak syrup amounts.

3.3 Why Using Quality Ingredients Makes a Difference

The quality of coffee beans, syrups, and creamers impact the overall flavor profile:

  • Arabica beans add smoothness.
  • Natural flavor syrups avoid artificial taste.
  • Fresh dairy or non-dairy creamers keep the drink balanced.
