--- title: Coca-Cola Zero Sugar (2017 reformulation): the brand-positioning move that produced sustained double-digit growth | RGM® url: https://realgrowthmatters.com/learn/case-studies/coca-cola-zero-sugar-2017-reformulation/ updated: 2026-06-10 source_html: https://realgrowthmatters.com/learn/case-studies/coca-cola-zero-sugar-2017-reformulation/ --- - **Story:** Coca-Cola reformulated and rebranded Coca-Cola Zero as Coca-Cola Zero Sugar in August 2017. Flavor adjusted closer to regular Coca-Cola; emphasis shifted to 'zero sugar' from 'zero calories'; packaging updated. Multiple years of double-digit volume growth followed. By 2023 it was the fastest-growing major Coca-Cola brand globally despite continued broader diet-soda category challenges. - **Why it matters:** Coca-Cola Zero Sugar is the defining recent example of successful product reformulation — addressing specific consumer feedback in a structurally-challenged category produced sustained growth. - **Takeaway:** Small-scale calculated reformulations are different from dramatic changes — the 2017 Zero Sugar reformulation worked partly because it was modest and to a sub-brand, not the flagship product. - **Takeaway:** Reformulation works when it addresses specific consumer feedback (flavor closer to regular Coke, sugar emphasis vs. calorie emphasis) rather than when it's driven by internal preferences. - **Takeaway:** Packaging and branding changes alongside the formulation change reinforce the consumer perception that the product has improved. ## Coca-Cola Zero Sugar reformulation — the four-step story S Situation Situation Coca-Cola Zero (launched 2005) had plateaued. Diet soda category overall was declining amid consumer concerns about artificial sweeteners and shifting toward unsweetened sparkling waters and other categories. T Task Task Reformulate and rebrand Coca-Cola Zero to address consumer feedback, attract new consumers, and capture growth in the diet-soda sub-category. A Action Action August 2017: reformulated flavor closer to regular Coca-Cola; rebranded from 'Coca-Cola Zero' to 'Coca-Cola Zero Sugar' emphasizing absence of sugar; new packaging design more closely resembling regular Coca-Cola. R Result Result Multiple years of double-digit volume growth post-reformulation through 2018-2023. By 2023 the fastest-growing major Coca-Cola brand globally despite continued broader diet-soda category challenges. ## Coca-Cola Zero Sugar by the numbers 0 Original Coca-Cola Zero launch No-calorie variant Source: Coca-Cola history 0 Zero Sugar reformulation US reformulation date Source: Coca-Cola announcement 0 Annual volume growth Multiple years post-reformulation Source: Coca-Cola earnings 0 Fastest-growing major brand Within Coca-Cola portfolio Source: Coca-Cola annual report 0 Key reformulation Adjusted toward regular Coca-Cola Source: Product disclosure 0 Brand emphasis shift From zero-calorie to zero-sugar Source: Brand positioning #### Quick facts BrandCoca-Cola Zero Sugar (parent: The Coca-Cola Company, NYSE: KO) Original launch2005 as Coca-Cola Zero (formulation different from Coca-Cola) First reformulationJune 2016 in Western Europe; rebranded to Coca-Cola Zero Sugar US reformulation2017 (rebranded from Coke Zero to Coca-Cola Zero Sugar) Second reformulationJuly 2021 (US, bringing taste even closer to original Coca-Cola) Strategic positioning“Coca-Cola without sugar” (vs Diet Coke as “lighter taste”) Reported growthSustained double-digit growth since 2017 reformulation Coca-Cola CEO during transitionMuhtar Kent (CEO 2008-2017), then James Quincey (CEO May 2017-present) Diet Coke positioningMaintained as “lighter taste” alternative targeting different consumer mindset **Honest note** Coca-Cola does not publish Coca-Cola Zero Sugar standalone revenue figures separately; the brand reports within the broader Sparkling Soft Drinks category. The double-digit growth figure is from Coca-Cola corporate communications and is widely cited in industry coverage. The 2017 reformulation was technically the European reformulation rolling out to the US, with the 2021 update being a further refinement. Specific reformulation ingredient changes and taste-test methodology have not been publicly disclosed in detail. ## Where Coca-Cola Zero was before 2016-2017 Coca-Cola Zero launched in 2005 (Coca-Cola Zero Sugar in some markets) targeting younger male consumers who saw Diet Coke as a women's product (Diet Coke had launched in 1982 with marketing aimed at women; the brand had become culturally associated with that audience). Coke Zero was positioned as a zero-calorie alternative that men could buy without the cultural baggage attached to Diet Coke. The marketing emphasised that Coke Zero tasted “more like regular Coke” than Diet Coke did. The 2005-2016 trajectory was successful but constrained. Coke Zero gained substantial share but the formulation actually tasted somewhat different from regular Coca-Cola — closer to Diet Coke in many blind tests. The brand positioning was working harder than the product positioning could sustain. Younger Coca-Cola consumers who tried Coke Zero often returned to either regular Coca-Cola or Diet Coke after trying it; the conversion from regular Coca-Cola to Coke Zero was limited by the taste gap. ## The 2016-2017 reformulation In June 2016 Coca-Cola launched a reformulated Coca-Cola Zero Sugar in Western Europe. The new formulation was designed to taste closer to standard Coca-Cola while maintaining zero-sugar content. The product also adopted new branding: the Coca-Cola Zero Sugar name (replacing Coke Zero) more explicitly communicated the “Coca-Cola taste without sugar” positioning. The packaging emphasised the connection to standard Coca-Cola with red-and-black color scheme rather than the all-black Coke Zero packaging. The 2017 US launch followed the same reformulation. The strategic positioning was deliberate: Coca-Cola Zero Sugar would be positioned as “regular Coke without sugar” for consumers who wanted the Coca-Cola taste without the calories; Diet Coke would remain as the “lighter taste” alternative for consumers who preferred a structurally different beverage. The differentiation gave Coca-Cola two distinct zero-calorie products serving two distinct consumer mindsets rather than competing against each other for the same audience. ## The 2021 second reformulation and post-reformulation growth In July 2021 Coca-Cola launched a further reformulation in the US that brought the Coca-Cola Zero Sugar taste even closer to original Coca-Cola. The 2021 reformulation was incremental refinement of the 2017 base — same strategic positioning, tighter taste-match execution. Industry coverage at the time emphasised that the 2021 reformulation made Zero Sugar nearly indistinguishable from regular Coca-Cola in blind taste tests. Coca-Cola has reported sustained double-digit growth for Zero Sugar since the 2017 reformulation. The brand has been one of the primary drivers of organic revenue growth in Coca-Cola's sparkling-soft-drinks segment through 2017-2024. The strategic positioning — “Coca-Cola without sugar” complementing “lighter-taste Diet Coke” — has held up well in market. The case has been widely studied as evidence that reformulation-and-rebranding can produce category growth when the underlying brand-positioning insight is real. ## How RGM thinks about beverage reformulation strategy When clients ask about beverage reformulation and brand-positioning resets, the Coca-Cola Zero Sugar case is the defining recent reference. Three structural lessons. First, the brand-positioning insight has to be real. The Coca-Cola Zero Sugar insight (some consumers want Coca-Cola taste without sugar; some want a lighter-taste alternative; these are different consumer mindsets that deserve different products) was substantively correct. Reformulations that try to bridge multiple consumer mindsets with one product often produce compromise outcomes that satisfy neither. Second, the rebranding alongside reformulation mattered. Going from Coke Zero to Coca-Cola Zero Sugar was a name-and-packaging change that communicated the new strategic positioning; companies that reformulate without rebranding often miss the opportunity to reset consumer expectations. Third, sustained execution beats one-time announcement. The 2017 reformulation was followed by sustained marketing investment, packaging consistency, and additional refinement in 2021. Reformulations that get the initial launch right but fail to invest in sustained execution often see initial gains fade. The pattern is hard to copy in beverage categories where the existing brand has unclear consumer-mindset segmentation. Coca-Cola benefited from having a clear segmentation (regular vs Diet vs Zero) that the Zero Sugar repositioning reinforced. PepsiCo, Dr Pepper, Mountain Dew, and other beverage companies have attempted similar reformulation strategies with mixed results depending on whether the underlying consumer-mindset insight was as clear. We tell clients in beverage and adjacent categories to think about whether the brand portfolio has clear consumer-mindset segmentation before attempting reformulation-driven repositioning. ## Frequently asked questions When did Coca-Cola Zero become Coca-Cola Zero Sugar? The rebrand and reformulation began in June 2016 in Western Europe and rolled out to the US in 2017. The 2017 reformulation kept the zero-sugar content but adjusted the formula to taste closer to standard Coca-Cola. A further reformulation in July 2021 brought the US taste even closer to original Coca-Cola. What's the difference from Diet Coke? Strategic differentiation. Coca-Cola Zero Sugar is positioned as “Coca-Cola taste without sugar” for consumers who want the Coca-Cola flavor profile without calories. Diet Coke is positioned as a “lighter taste” alternative for consumers who prefer a structurally different beverage. The two products serve different consumer mindsets rather than competing for the same audience. How well has it performed? Coca-Cola has reported sustained double-digit growth for Coca-Cola Zero Sugar since the 2017 reformulation. The brand has been one of the primary drivers of organic revenue growth in Coca-Cola's sparkling-soft-drinks segment through 2017-2024. Specific revenue figures are not broken out separately; Coca-Cola reports Zero Sugar within the broader sparkling-soft-drinks category. Why was the 2017 reformulation important? The original 2005 Coke Zero formulation actually tasted somewhat different from regular Coca-Cola — closer to Diet Coke in many blind tests. The 2017 reformulation closed that gap, supporting the strategic positioning of “Coca-Cola taste without sugar.” The rebrand from Coke Zero to Coca-Cola Zero Sugar reinforced the positioning by more explicitly communicating the connection to standard Coca-Cola. What about the 2021 second reformulation? In July 2021 Coca-Cola launched a further reformulation in the US that brought the Coca-Cola Zero Sugar taste even closer to original Coca-Cola. The 2021 update was incremental refinement of the 2017 base — same strategic positioning with tighter taste-match execution. Industry coverage emphasised that the 2021 reformulation made Zero Sugar nearly indistinguishable from regular Coca-Cola in blind taste tests. Who led the reformulation strategy? Muhtar Kent was Coca-Cola CEO during the 2005 Coke Zero launch and the early reformulation work. James Quincey became CEO in May 2017 and led the broader strategic positioning of Coca-Cola Zero Sugar through the global rollout and the 2021 further reformulation. ### Sources & references - [Coca-Cola Zero Sugar (Wikipedia)](https://en.wikipedia.org/wiki/Coca-Cola_Zero_Sugar) — Aggregated reference for the brand history including the 2005 launch, 2016 European reformulation, 2017 US reformulation, and 2021 further reformulation. - [Coca-Cola launches reformulated Coca-Cola Zero Sugar in the US (Beverage Daily, July 2021)](https://www.beveragedaily.com/Article/2021/07/13/Coca-Cola-launches-reformulated-Coca-Cola-Zero-Sugar-in-the-US/) — Industry coverage of the July 2021 reformulation. - [Coca-Cola changes taste of Zero Sugar to be more like Coke (Food Dive)](https://www.fooddive.com/news/coca-cola-changes-taste-of-zero-sugar-to-be-more-like-coke/603188/) — Food industry coverage of the reformulation strategy and consumer response. - [A bet for the future: Zero Sugar's role in driving growth (Marketing Week)](https://www.marketingweek.com/future-zero-sugar-coca-cola/) — Marketing industry analysis of Zero Sugar's contribution to Coca-Cola growth. - [Coke Zero is out, Coca-Cola Zero Sugar is in (KCEN-TV)](https://www.kcentv.com/article/news/nation-world/coke-zero-is-out-coca-cola-zero-sugar-is-in/500-459790420) — Coverage of the brand transition from Coke Zero to Coca-Cola Zero Sugar. - [Coca-Cola Q3 2017 8-K (SEC)](https://www.sec.gov/Archives/edgar/data/0000021344/000002134417000029/a2017q3earningsreleaseex-9.htm) — Coca-Cola SEC filing from the year of the US Zero Sugar rebrand. ## Related [#### All case studies The full case-study library.](/learn/case-studies/)[#### Diet Coke positioning history The sister brand whose positioning the Zero Sugar strategy was built against.](/learn/case-studies/)[#### Celsius energy drink Adjacent beverage-category brand-positioning case.](/learn/case-studies/celsius-energy-drink-fitness-positioning/)
