Pure amber, which is distilled from tree resin, can smell "almost slightly pissy", in Christopher's words--but he insists that when it's used correctly it is quite alluring. "Americans have this idea that everything needs to smell clean, clean, clean", he laments, with a shake of his head. He counters the trend for sanitised fragrances with creations like Wild Hunt, which is full of delightful earthy notes, including (according to his literature) "torn leaves, crushed twigs, flowing sap, fallen branches, old leaves, green moss, fir, pine and tiny mushrooms".
