Petrichor

About

Petrichor is the scent of rain hitting dry earth: damp mineral and clay facets mingling with dusty, humic warmth, a whisper of metallic-ozonic air, and mushroomy geosmin, often with a green snap. It evokes summer storms, darkening soil, wet stone, sidewalks after heat, and the awakening forest floor. In perfumery it is built as an accord using geosmin or earthy molecules, mushroom notes, patchouli, vetiver, oakmoss, and airy ozonic–mineral materials, sometimes brightened with violet leaf or galbanum. Used to add realism and atmosphere, it anchors aquatics, fougères, and woody-green compositions or creates a vivid rainfall effect.
