Rain itself has very little scent. What we perceive as the smell of rain is actually a combination of compounds released from the earth, plants, and atmosphere during and after a storm. One of the most famous materials associated with rain is Geosmin, a naturally occurring molecule produced by bacteria. It is responsible for the earthy aroma that rises from the ground after rainfall, known as petrichor. Humans are incredibly sensitive to geosmin and can detect it at extremely low concentrations. Creating a rain accord is less about reproducing water itself and more about recreating the atmosphere surrounding a rainstorm. Damp soil, wet stone, soaked concrete, crushed leaves, cool air, and distant ozone all contribute to the illusion. For this accord, geosmin provides the earthy foundation while carefully selected materials add mineralic, aquatic, green, and ozonic facets. The goal is not simply to smell like rain, but to capture the feeling of standing outside after a storm as the clouds begin to part and the world slowly comes back to life.
