Quick answer

Choose the SodaStream Diet Pepsi Drink Mix if you want a zero-sugar cola with the same classic Pepsi taste. Pick the original Pepsi Drink Mix if you prefer the full-sugar cola experience.

Taste and sweetness: real sugar vs zero sugar

The original SodaStream Pepsi Drink Mix uses sugar for sweetness, delivering the familiar full-calorie cola taste. The Diet Pepsi Drink Mix relies on artificial sweeteners to mimic that flavor without any sugar. Some people notice a slight aftertaste with diet versions, but many find it nearly identical. If you are sensitive to artificial sweeteners, the original is the safer choice.

Calories and dietary goals

Each serving of the original Pepsi Drink Mix adds about 100 calories from sugar. The Diet Pepsi Drink Mix has zero calories, making it a better fit for low-calorie or keto lifestyles. If you are watching your sugar intake, the diet version lets you enjoy cola without the carbs.
