The Pepsi Challenge

The Pepsi Challenge returns – and it's coming to Des Moines for the Iowa State Fair!

PEPSI® is bringing the iconic blind taste test to your area, inviting consumers to put their taste to the ultimate test and decide for themselves who has the superior-tasting cola.

Last year, the Pepsi Challenge results were undeniable. In 2025, Pepsi Zero Sugar beat Coca-Cola Zero Sugar in the majority of stops along the national Pepsi Challenge tour — including Atlanta, Coke’s hometown — with more than 66% of participants choosing Pepsi Zero Sugar.

Now, fans in the Des Moines area will have the chance to take the famous challenge. And this year there's even more flavor on the table – with attendees putting Pepsi Zero Sugar Wild Cherry to the test too.
