== Comparison Article ==
Coca-Cola Zero Sugar and Diet Coke are the two primary low-calorie carbonated soft drinks manufactured by The Coca-Cola Company. While both products contain no sugar and no calories, they are distinguished by their chemical formulations, flavor profiles, and historical marketing objectives.

== History and formulation ==

Diet Coke was introduced in 1982 as the first sugar-free brand extension of the Coca-Cola trademark. Unlike later products, Diet Coke was not designed to replicate the taste of original Coca-Cola. Instead, it used a distinct flavor base, which some tasters describe as having a lighter or more citrus-forward profile. This formulation was later used as the basis for New Coke in 1985.

Coca-Cola Zero was launched in 2005. The primary goal of this product was to provide a sugar-free alternative that closely mimicked the flavor of Coca-Cola Classic. To achieve this, chemists used the original Coca-Cola flavor profile and adjusted the sweetener blend. In 2017, the product was rebranded as Coca-Cola Zero Sugar with a revised recipe intended to further align the taste with the standard red-label version. Another recipe update occurred in 2021, which included changes to the packaging and flavor balance.

== Ingredients and sweeteners ==

The main difference in ingredients lies in the sweetener system. Diet Coke is sweetened almost exclusively with aspartame in most markets. Coca-Cola Zero Sugar uses a blend of aspartame and acesulfame potassium (also known as Ace-K). The combination of these two sweeteners is intended to create a more rounded sweetness that lacks the specific aftertaste sometimes associated with single-sweetener diet sodas.

The caffeine levels also vary between the two products. In the United States, a 12-ounce can of Diet Coke contains approximately 46 milligrams of caffeine, while a 12-ounce can of Coca-Cola Zero Sugar contains 34 milligrams. Both drinks use phosphoric acid and caramel color, similar to the original Coca-Cola recipe.

== Market positioning ==

The two products were originally created to reach different consumer segments. Diet Coke was initially marketed toward women and individuals focused on weight management. The brand became a staple of the 1980s and 1990s diet culture.

Coca-Cola Zero was developed to appeal to a broader demographic, particularly men who preferred the taste of regular Coca-Cola but wanted to avoid sugar. Early advertising for Coke Zero avoided the word "diet" entirely, using black packaging to differentiate the product from the silver-themed Diet Coke. Despite the overlap in the low-calorie market, the company continues to produce both brands due to the loyal consumer base for the specific flavor of Diet Coke.
