Diet Coke has launched the next phase of its ‘This Is My Taste’ campaign with actor Jamie Dornan. This new chapter celebrates personal passions, featuring Dornan’s love for cold-water swimming in fresh, inspiring content.

The campaign is based on the insight that the average Diet Coke break lasts just eight minutes. The creative message encourages people to reclaim this time as a powerful moment for self-expression and enjoyment.

Building on last year’s partnership, this instalment captures the thrill of cold-water swimming—something Dornan genuinely enjoys—and pairs it with the refreshment of a Diet Coke break. The aim is to celebrate individuality and motivate audiences to embrace what makes them unique.

Filmed at Shepperton Open Water Swim in Surrey, the hero ad shows Dornan sipping an ice-cold Diet Coke before diving into icy waters. Along the way, he meets quirky characters enjoying their own breaks-from birdwatchers to radio-control boaters to paddleboarders.

The campaign uses a mix of TV, social media, influencer partnerships, and PR to reach audiences across Great Britain and Ireland, encouraging them to express their personal tastes.
