IRN BRU - Legendary Flavours
By Leith
Our mission at Leith was to bring these enigmatic flavours to life, captivating millennials and Gen Z with content that embodies classic Bru: a bit of escapism, a lot of laughter, and a wee bit of joy.
The Challenge
For the past two years, IRN-BRU has been shaking up the summer with new, limited-edition XTRA flavours, grabbing more shelf space and keeping the brand feeling fresh and unexpected. But in May 2025, they wanted to go bigger, bolder, and even more audacious by concocting not one, but two mystery XTRA flavours, inspired by the weird and wonderful things people already say Bru tastes like.
The names? Nessie Nectar and Unicorn Tears.
The Leithal Thinking
To truly unleash the "XTRA" in these mystery flavours, we imagined the absurd: what would it really be like to source Nessie Nectar or harvest Unicorn Tears? Our answer? A mockumentary.
We delved into the fantastical lives of a Nessie Nectar Milker and a Unicorn Tear Farmer. Our content explores the rather peculiar process of milking nectar directly from Nessie's… well, teat. And for Unicorn Tears? We explored various, equally ridiculous techniques, from hurled insults to classic tear-jerkers, all designed to get those precious, potent droplets.
The Results
Our films were a hit with the tough-to-impress Tik-Tokkers– creating massive engagement, loads of shares, and a feelgood vibe. They saw summer sales soar. And they even made the local headlines.
