Mimosa
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.”
