Спосіб отримання
Soil or peat is macerated in high-proof ethanol (90-95%) over several weeks to months. Finely sifted soil or peat is soaked in the ethanol, which dissolves aromatic and non-aromatic compounds including resins, pigments, waxes and microbial metabolites like geosmin. The resulting tincture is filtered and aged to enhance clarity and complexity. The raw material is typically collected from specific terroirs such as forest floors, peat bogs or clay-rich agricultural soils. Different soil types, such as peat bog, clay-heavy agricultural soil or forest floor, yield tinctures with unique olfactory nuances, from smoky acidity to dry mineral or fungal complexity. There is no standardized yield data because production is artisanal.

У парфумерії
Soil tincture is classified as a base note because of its low volatility and long-lasting presence. It is typically used at trace levels, often less than 0.5%, to add authenticity and a grounded sense of place to compositions. It gives a naturalistic earthiness distinct from other earthy notes like patchouli or vetiver. Geosmin, the earthy molecule of soil, is used in perfumes to confer an earthy scent, and at low concentrations its earthy note may add freshness.
