Coca-Cola Zero Sugar

Coca-Cola Zero Sugar, also known as Coca-Cola No Sugar, commonly known as Coke Zero, is a diet soda produced by the Coca-Cola Company. The drink was introduced in 2005 as Coca-Cola Zero, designed to be a no-calorie equivalent of the company's flagship cola drink, Coca-Cola, with artificial sweeteners in place to imitate the sugar taste. It is distinct from the company's earlier Diet Coke product which was based on an entirely different formula. In 2016–2017, the drink was reformulated and the name changed to Coca-Cola Zero Sugar (with language variations for some regions), and the drink was reformulated again in 2021.

Coca-Cola Zero was Coca-Cola's largest product launch in 22 years and was also important because of a dip in standard Coca-Cola sales and lackluster sales of their "mid-calorie" product Coca-Cola C2. The new product was ideated at the Spanish branch,^{[citation needed]} turning Marcos de Quinto into one of the key people of the company. The global campaign was developed by creative agency Crispin Porter + Bogusky. It was marketed as having a taste that is indistinguishable from standard Coca-Cola, as opposed to Diet Coke, which has a different flavor profile.

Initially the drink was sold in the United States and Canada and branded in white packaging. However following its successful Australian launch in January 2006 where it used black packaging, the black was then also adopted for all other markets. After its North American and Australian launches, it was released in Spain and then rolled out to further territories around the world.

Beginning in June 2016, Coca-Cola Zero was relaunched in western Europe as Coca-Cola Zero Sugar with a new reformulation, namely in Belgium, France, Great Britain and the Netherlands. The new formula was intended to taste more like standard Coca-Cola while emphasizing the lack of sugar content with the addition of "Sugar" in its full brand name. A year later, in 2017, the Coca-Cola Company announced that the new formula and name will be rolled out in the United States (and in other countries), despite increasing sales of the existing drink there. The announcement caused some vocal backlash from American consumers. The Washington Post noted Coke Zero is very popular, and that fans compared the planned change to the launch of New Coke in 1985. However, Beverage Digest executive editor Duane Stanford noted that it was very similar in flavor, and that the formula likely was tweaked only slightly as the ingredients list is the same. He noted that the rebranding was the main emphasis. In Australia (where it was relaunched as "Coca-Cola No Sugar"), the new soda had trouble gaining initial acceptance but later became more popular.

In July 2018, it was confirmed that the original formula would continue to be sold under the original Coke Zero branding in New Zealand alongside the Coke Zero Sugar product. The original Coke Zero branding was finally phased out in 2022 alongside the local launch of the 2021 reformulation.

In July 2021, the Coca-Cola Company announced that another reformulation of Coca-Cola Zero Sugar would be released throughout the U.S. in August and then throughout Canada in September. The reformulation would be the same recipe that was already available in Europe and Latin America. The company said the recipe would "optimize existing...flavors and existing ingredients" without requiring a change in the listed ingredients or nutritional information. Along with the reformulation, the labeling was updated. Around September 2024, the Coca-Cola Company further adjusted the formulation by adding Stevia.

Originally the Coca-Cola Zero product packaging on cans and bottles consisted of the Coca-Cola logo in red script with white trim, with the word "zero" underneath, on a black background. The font for "zero" was the geometric typeface Avenir (or a customized version of it).^{[citation needed]}

Later packagings, when the product took the name Coca-Cola Zero Sugar, swapped the colors, appearing in a red disc on a black background, as part of the company's "One Brand" wider rebranding to unify the Coca-Cola packagings closer together. In overseas markets, the packaging instead matched the classic Coca-Cola red design with the addition of a black band around the top of the label with the text "zero sugar" (or non-English equivalent). In 2021, after the reformulation, a new livery was introduced featuring the Coca-Cola logo in black against a red background, although the color of the background changes for certain other flavors.
