Extraction process :
The plants that constitutes hay are deliberately planted for their growth and dried in the sun. Large areas of culture are needed as these plants are invasive. The cultivation of hay is made by vehicles like tractors or with a scythe, once the herbs are dried.
Hay absolute is obtained by macerating the hay in hexane in order to obtain a concrete of hay. After removing the plants from the extractor and evaporating the hexane, the concrete is collected and the hexane recycled. The concrete is diluted in alcohol and glazed at 32 °F. After evaporation of the solvent, the absolute is obtained.
Sometimes the hay absolute can be distilled to be bleached, without a great olfactory impact.

- Uses in perfumery :
- Used in luxury perfumery for chypre, fougere, amber, tobacco and for a long-lasting aromatic note.
- Other comments :
- Hay is a mixture of sun-dried plants : mainly sweet vernal grass, sweet-scented bedstraw and liatrix among others. The drying allows to evaporate the smell molecules of the most volatile plants and allows to keep the heavier molecules only.
The presence of liatrix in particular contributes to the high rate of coumarin of this absolute (about 15%). These characteristics of culture explain its good tenacity. - Volatility :
