Coca-Cola Improves a Drink Nobody Asked to Be Improved; Un-Improves It 79 Days Later

Spooked by the Pepsi Challenge, Coke reformulated its 99-year-old recipe sweeter. America revolted, hoarded the old stuff, and had 'Coca-Cola Classic' back by summer.

What wasn’t broken
Coca-Cola was the best-selling soft drink on the planet, its formula essentially untouched since 1886. By every measure that matters to a beverage, it was working.
The "fix"
Rattled by the 'Pepsi Challenge' taste tests and a slipping lead, Coke spent some $4 million and ran nearly 200,000 consumer taste tests, then on April 23, 1985 scrapped the old recipe for a sweeter 'New Coke.'
The result
The public did not say thank you. Protest groups formed, the company fielded thousands of angry calls a day, and shoppers cleared shelves to hoard the original — and on July 11, 1985, just 79 days later, 'Coca-Cola Classic' came back. Fuxed

In the spring of 1985 the Coca-Cola Company did something nobody had asked it to do: it improved the most popular soft drink on Earth. The recipe had been essentially unchanged since 1886 and outsold every rival; the trouble, as the executives saw it, was that Pepsi kept winning the 'Pepsi Challenge' — those televised sip tests in which people tended to prefer the sweeter cola.1

So Coke went to the lab. The company spent a reported $4 million and ran close to 200,000 taste tests, in which a sweeter reformulation beat both Pepsi and the original. The data looked airtight. On April 23, 1985, chairman Roberto Goizueta unveiled 'New Coke' and retired the 99-year-old formula.2 What the taste tests had not thought to measure was how people feel about being told their favorite thing has been discontinued.

The response was not gratitude. It was grief, and then fury. Consumers cleared store shelves to hoard the old formula; a Seattle retiree founded the 'Old Cola Drinkers of America' and threatened to sue; the company's hotline took as many as 1,500 calls a day plus tens of thousands of letters, the overwhelming majority outraged.3 People who had never given the recipe a second thought discovered, the moment it vanished, that it was load-bearing.

Coca-Cola surrendered. On July 11, 1985 — a mere 79 days after the launch — it announced the return of the original as 'Coca-Cola Classic,' news so big that ABC broke into General Hospital to report it.4 New Coke lingered for a few years and was quietly retired; Classic eventually became, simply, Coke again. The fix had taken a drink that was winning, declared it a problem, solved the problem, and then spent the summer un-solving it — a case study taught ever since under the heading of what not to do.1

All the time and money and skill poured into consumer research on the new Coca-Cola could not measure or reveal the deep and abiding emotional attachment to original Coca-Cola felt by so many people.— Donald Keough, Coca-Cola president, July 1985
