Summary: The fragrance industry used to cater for the tastes of London, Paris and New York, but times are changing. New economies are the future, but what we like in a smell changes with time and location, and perfumers have to a lot of homework to do. The fastest-growing market of all is Brazil, where citizens are obsessed with everything fragranced. We're with perfumers as they peer into bathroom cabinets to monitor minute shifts in taste, and with an American scent guru who has to get up the noses of Latin adolescents in order to define the smell of the next version of a bodyspray. An ancient English perfume house remakes Oriental fragrances that amused Queen Victoria. The tastes of modern Britain have moved on, but in the Gulf States they like these hot and heavy scents and we follow them as they as they try to make it big in Bahrain.
