PepsiCo is launching a new ad campaign for Diet Pepsi next month

PepsiCo has said a sweetener change for its Diet Pepsi brand won't affect its flavour.

The new blend, exclusive to the US, mirrors the formula used in Diet Pepsi Wild Cherry and Diet Pepsi Vanilla, a PepsiCo spokesperson told just-drinks yesterday (17 December). The company has also revealed details of a major new ad campaign. 

“We’ve done qualitative testing and are confident that there is no change to the flavour of the product,” the spokesperson said. 

Diet Pepsi in the US now contains a blend of sweeteners Ace-K and aspartame, whereas previously it was only sweetened with aspartame, The Associated Press reported. Aspartame breaks down in its journey from factory to fridge and the report suggested the change was made to maintain sweetness. The new mix started hitting shelves early this month and will become more widely available as stocks roll out, the report said.

PepsiCo said a new ad campaign for Diet Pepsi next month will feature US sit-com actress Sofia Vergara. The spokesperson said the ad spend will be higher than in recent years, “reflecting a renewed emphasis on the brand here in the US”. 

In August, PepsiCo denied it was to change Diet Pepsi's overall formula in the US.
