A true maverick in the world of the independent perfumer, Sarah McCartney has a wonderfully irreverent attitude to creation. She came from a journalistic background, not a chemistry background, discovered a love of perfume making, and with an eccentric approach has created some of the most challenging fragrances on the market under the name 4160 Tuesdays. Anyone who has smelt Dark Heart Of Old Havana will know that this woman has the ability to bottle pure sexual desire. So, with some trepidation, it was time to ask her "Stephan's Six".
