Cointreau X SunSeekr

Discover how Cointreau and the SunSeekr app turned London’s (and later Amsterdam’s) real-time sunshine into a live map of the best terraces for a Cointreau Spicy Margarita.

How Cointreau extended London’s summer.


There was a particular London optimism that arrived with a September afternoon, and Cointreau bet on exactly that feeling. The Maison partnered with SunSeekr, the sunshine-mapping app that went viral that summer, to launch a first-of-its-kind live guide to London’s sunniest terraces for a Spicy Margarita.

From 3 to 30 September, the interactive map followed the sun across the capital and updated throughout the day. An east-facing terrace in the morning, a rooftop at full noon, a riverside bench glowing at golden hour: wherever the warmth landed, the next margarita was never far.

It all shone a light on Cointreau Spicy, the Maison’s first chilli-infused expression, which had arrived in the UK that July. And it landed at the perfect moment: the Margarita continued to dominate cocktail culture, while its spicy cousin was having a breakout year.

The map also pointed the way to selected Sainsbury’s stores, for anyone who preferred to bring the sunshine home. A bottle of Cointreau Spicy, a few limes, and the rest took care of itself.
 

“Cointreau Spicy is all about bringing warmth, vibrancy and sociability to those last outdoor moments, and partnering with SunSeekr felt like the perfect way to help people enjoy a Spicy Margarita in the sunshine.”

- Kevin Sueiro, Cointreau Brand Ambassador




From London to Amsterdam

Taking the sun-chasing journey further, Cointreau and SunSeekr expanded the real-time terrace guide to Amsterdam’s sunniest canals.

How we brought the sunshine home

Bridging on-trade discovery with retail conversion, the SunSeekr map also guided users to nearby Gall & Gall stores across the Netherlands. This gave consumers an easy way to recreate the Spicy Margarita experience at home, spotlighting Cointreau Spicy as the effortless solution for at-home hosting—delivering the perfect kick without the guesswork.

DISCOVER COINTREAU SPICY

The maison’s first chilli-infused expression, Cointreau Spicy brings bold, natural heat to the world’s most-loved cocktails, built on the same orange-peel distillation expertise behind the original 1875 recipe. It takes the guesswork out of the perfect Spicy Margarita: no fresh chillis, no experimenting with the spice level. Just the right balance of citrus and warmth, every time.
