Since arriving at Louis Vuitton in 2012, master perfumer Jacques Cavallier Belletrud has focused on contrasts within his fragrances, combining notes that wouldn’t normally mingle. For his latest creation, Attrape-Rêves ($265), for which he wanted to “put dreams and very positive vibes in a bottle,” he set his sights on cocoa. “It reminds me of my childhood, when I used to open a box of chocolate powder, but it is sensual at the same time,” he says. To contrast with the softness of the cocoa, he tweaked the acidity of the lychee and added a hint of ginger to play with the patchouli. Lastly, he added bergamot oil to bring freshness and also make the lychee lighter. “The dialogue between these different smells is like a firework when you open the bottle,” he says.
