Samuel Maruta and Vincent Mourou wouldn’t be the first characters to create magic from a humble bag of beans. However, the duo behind Marou: Faiseurs de Chocolat – Vietnam’s first and, thus far, only line of single-origin chocolate bars – have enjoyed a fairy-tale rise every bit as vertiginous as Jack’s beanstalk. Retailers in a host of international markets including France, Japan, the UK and Sweden now stock their five-strong range of chocolate bars. Culinary big-hitters such as multiple- Michelin-starred-chef Michel Roux and Willie Harcourt Cooze, the British celebrity chocolatier, have given their approval. Meanwhile, Marou has starred at international events – Paris’ Salon Du Chocolat, for one – and has secured a host of awards at prestigious chocolate events across the globe.
