The smell we all associate with the first rains after a dry spell, or disturbing earth after a rain is call petrichor (pet-ree-kor). It is the result of soil disturbance by the rain, releasing geosmin, an organic compound with a distinct earthy flavour and aroma produced by actinobacteria and cyanobacteria.

I used to work in a lab where we grew hundreds of flasks of the stuff looking for new antibiotics. The smell of petrichor blasting me from a heated grow-room first thing on a Monday morning is one of my favourite memories of working there.

Not something that has happened much of late......

And 'petrichor' is a lovely word
