Euphoria Lophophora III 🌵Petrichor, that fresh aroma you can smell after the rain, is caused by a little molecule called geosmin. The name literally means "earth smell." It's produced by soil bacteria and gives an earthy flavour to beets.
Humans are extremely sensitive to this scent – much, much more sensitive than sharks are to blood. Some think we evolved that way to find fresh drinking water after droughts.
