The Pepsi challenge is back but will it work this time?

Pepsi Challenge in Stockholm

The Pepsi challenge is one of those things people of my generation remember well. It caused a fuss and likely upset a lot of coke-cola fans. But over the decades since, people like Malcolm Gladwell have reasoned why the test its self was broken.

In his book Blink: The Power of Thinking Without Thinking (2005), author Malcolm Gladwell presents evidence that suggests Pepsi’s success over Coca-Cola in the “Pepsi Challenge” is a result of the flawed nature of the “sip test” method. His research shows that tasters will generally prefer the sweeter of two beverages based on a single sip, even if they prefer a less sweet beverage over the course of an entire can.

Regardless Pepsi has decided to do the whole thing again comparing Pepsi Max against full sugar Coca-Cola. The taste test is next week in Manchester at Market Street on Saturday 25th August and then Sunday 26th in Piccadilly Gardens.
