Her scents are composed as portraits of places and occasions: Ealing Green is a crisp green floral named for the west London suburb where McCartney met her husband; Maxed Out is a boozy mix of rum, tobacco, cannabis, coffee and a hint of hot sweat, modelled on a New York night out and not for the faint of pulse. “I can make something outrageous and, if only a small group of people love it, I just never make a bigger batch,” McCartney says. “As we do everything by hand here our costs are higher, but nothing is ever wasted.
