Soil: Fragrance Profile

1. Overview

• Perfume inspiration: Earth, rain, and fertile ground.

• Natural source:

  • The smell of wet soil after rain is largely due to geosmin (produced by soil bacteria).

  • Petrichor → the fresh, earthy scent when rain hits dry ground, caused by plant oils + geosmin.

  • In perfumery, “soil” is usually created as an accord (synthetic reconstitution) or through earthy natural materials (vetiver, patchouli, oakmoss).

• Note type: Base–accent note.
