The unmistakable scent of rain comes from bacteria, not clouds.
As raindrops fall, they agitate the soil and bring out a chemical called geosmin, which is made by microbes in the dirt. It has an earthy aroma, and sometimes ruins the flavor of food particularly water, wine, beets and fish by making it taste dirty.
It took three decades of tinkering before chemists learned how to prepare it with ease. Geosmin's future is uncertain perhaps dirt-scented cologne?
