Did you know that the specific, earthy-ozonic-fresh scent that comes after the first rain in a while or after a storm is not a matter of accident? We can experience this scent effect thanks to a fragrance molecule known as geosmin. It’s produced by Streptomyces bacteria and some cyanobacteria that live in the ground. When they die they release said compound. Our noses are very sensitive to this bicyclic alcohol. Modern perfumery utilizes geosmin sometimes but nobody uses bacteria for that – it’s produced synthetically in the lab (the synthesis method is known since 1968).
Do you like the smell of the ground after the rain? Would you like it to be used in perfume more?
