Tim Hortons Diet Coke

Diet Coke is made with carbonated water, aspartame (a low-calorie sweetener), caffeine, citric acid, phosphoric acid, potassium benzoate (a preservative), and natural flavors. No sugar or calories come from these ingredients, allowing for a drink that’s non-caloric.

Diet Coke has a crisp, slightly tangy flavor with a characteristic cola taste. It offers effervescence and a light sweetness from the artificial sweetener, without the heaviness of traditional sugary colas. The aftertaste can be a bit distinct due to the aspartame, which some may prefer to avoid.
