Diet Coke and Rubicon Mango In a Fictional Co-Brand

A Major Brand Collaboration

A new mockup is proposing one of the more unexpected soft drink collaborations. The image shows a 500ml bottle of Diet Coke, but with a significant addition: the branding and flavour of Rubicon Mango. This concept presents a direct co-branding exercise between two completely separate entities, The Coca-Cola Company and A.G. Barr, Rubicon’s parent company.

Such a move would be almost unprecedented for Diet Coke in the UK. While the core Coke brand sees regular flavour innovations, the Diet Coke line-up has remained focused and conservative for years. The bottle in the image features the classic silver Diet Coke livery, but it’s overlaid with Rubicon’s distinct yellow and green colourway and its familiar logo. A banner at the top announces it as part of the “Real Flavour Innovation Editions,” a fictional range created for the concept.

The Current Diet Coke Range

Placing this concept in the context of the real world highlights just how ambitious it is. The current Diet Coke range on UK shelves is extremely narrow. Aside from the original, the only permanent fruit flavour is Diet Coke Cherry, which is also available in a 2-litre format. The only other official variant is Diet Coke No Caffeine.

That’s it. There is no existing portfolio of exotic or experimental flavours for this proposed mango edition to join. Unlike Coke Zero Sugar, which has had a broader and more experimental flavour strategy, Diet Coke’s identity is built on a very stable and limited set of options. The introduction of a flavour as specific as mango, let alone one tied to a different company’s intellectual property, would represent a complete reversal of its market strategy.

What the real range looks like

The current Diet Coke range in the UK includes the original, Diet Coke Cherry, and Diet Coke No Caffeine. A mango co-brand with Rubicon would be a significant departure from this small, established lineup.
