Why Does McDonald’s Diet Coke® Taste Better at McDonald’s?

McDonald’s follows strict Coca-Cola® guidelines, ensuring the perfect syrup-to-water ratio. The syrup and water are pre-chilled before entering the soda fountain, and the ice melts at just the right rate to enhance the flavor. This attention to detail makes every sip of Diet Coke® refreshing and satisfying.
