Coca-Cola Zero Sugar (2017 reformulation): the brand-positioning move that produced sustained double-digit growth

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.
