What is the difference between diet coke and coke zero?

While both Diet Coke and Coke Zero are cola drinks without sugar, they differ slightly in their sweetener blends and resulting taste profiles:

• Sweetener: Diet Coke traditionally uses aspartame (along with acesulfame potassium in some regions) as its primary artificial sweetener. Coke Zero typically uses a blend of aspartame, acesulfame potassium, and sometimes sucralose. The exact blend can vary by region and may change over time. This difference in the sweetener blend contributes to their differing tastes.

• Taste: Many people perceive a difference in taste between the two. Diet Coke often gets described as having a sweeter, slightly more "classic Coke" taste (though obviously without the sugar), whereas Coke Zero is frequently described as having a more bitter or slightly more artificial aftertaste by some consumers. This subjective difference is largely attributed to the different artificial sweetener profiles.

• Calories and Macros: Both have virtually zero calories and carbohydrates (though minuscule amounts may be present due to natural variations in ingredients).

• Other Ingredients: Beyond the sweeteners, there are minor variations in the other ingredients of Diet Coke and Coke Zero, though these are subtle and don't significantly affect the overall product.

In short: While both are sugar-free Coca-Cola alternatives, the blend of artificial sweeteners leads to a noticeable difference in taste preference for many people. Ultimately, which one you prefer comes down to personal taste.
