The rustic cabin aboard the HMS 'Beagle,' the boat where Charles Darwin wrote his 'Origin of the Species,' is the inspiration behind this woody, spicy "agua de perfume" redolent of cedar, vetiver grass, and grapefruit – all essences sourced and handmade in Patagonia (where, you may be surprised to know, Darwin spent more time than in the Galápagos Islands). Soft, sweet, and musky, it's a – wait for it – natural selection for the sort of evening when intellectual small talk gets batted about over a little fine wine or whiskey.
