Hay

Hay is meadow grass cut and then dried in the sun. As they dry, some plants, such as sweet vernal grass, release coumarin, which gives hay its sweet smell, between almond, blond tobacco and honey. An absolute is obtained from it by solvent extraction, and perfumers also recreate its note with coumarin.
