Character
How it smells
The ancient scent of mineral-rich earth, captured.
The characteristic petrichor scent comes from geosmin, a compound produced by soil bacteria that humans can detect at just 0.4 parts per billion.
Origin
France
The association between earth and fragrance stretches back to the earliest human rituals. Ancient Mesopotamian and Egyptian perfumers worked extensively with earthy materials, though the specific 'clay note' as understood today emerged much later. Traditional perfumery used actual earth and clay in burial ceremonies and sacred rituals.
The modern interpretation of clay as a perfumery note developed alongside synthetic chemistry in the late 19th and 20th centuries. Today, clay notes connect contemporary fragrances to primal human connections with the earth, appearing in perfumes that aim to evoke nature in its most elemental form.
