A bottled-water launch built on an awkward source
Dasani’s UK launch ran into a problem before many customers had even tried it: the water began as ordinary tap water. Coca-Cola purified the supply and added minerals to give the finished product a consistent taste. That process was legal, but it made the brand’s premium bottled-water pitch harder to sell. If shoppers saw Dasani as tap water in a bottle, they had less reason to pay extra for it.
How bromate entered the story
The more urgent problem came from bromate, a chemical that can form when ozone—used to disinfect water—reacts with naturally occurring bromide. Bromate is treated as a potential cancer risk, so drinking-water rules set strict limits on how much can be present. Reports that Dasani exceeded the applicable limit turned a product-positioning problem into a safety and regulatory crisis.
The issue was not that all treated water necessarily contains dangerous levels of bromate. It was that a bottled product sold as carefully purified had failed a standard customers expected it to meet. Coca-Cola withdrew the water rather than continue a launch already under intense scrutiny.
Why the setback mattered
For a bottled-water brand, trust is part of the product: customers are paying for confidence as much as for hydration. Dasani’s source invited comparisons with cheaper tap water, while the bromate reports gave those comparisons a sharper edge. The launch therefore lost on both value and reassurance—the two things a premium water label needs to provide.
