- Flavors: Diet Coke was designed to have a distinct flavor that differs from the original Coca-Cola. It’s slightly lighter and crisper in taste.

Coke Zero (Now Known as Coke Zero Sugar):

- Sweeteners: Aspartame and Acesulfame Potassium (Ace-K).

- Flavors: Coke Zero was formulated to taste as close to regular Coca-Cola as possible, offering a near-identical flavor without the sugar.

 

2. Taste and Flavor Profile

One of the key factors that differentiates these two beverages is the taste:

Diet Coke:

Unique Flavor: Diet Coke has a flavor that’s somewhat citrusy and different from regular Coca-Cola. This was intentionally done to set it apart as its own product, rather than a direct replica of classic Coke.

Coke Zero:

Similar to Classic Coca-Cola: Coke Zero’s formulation aims to mirror the taste of regular Coca-Cola, making it an appealing option for those who want the classic Coke flavor but without the sugar or calories.
