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

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.

Take the diet pepsi challange and I will make it easy by forgetting to cover the cans
