Geosmin, which literally translates to "earth smell", is an organic compound with a distinct earthy flavour and aroma, and is responsible for the earthy taste of beets and a contributor to the strong scent that occurs in the air when rain falls after a dry spell of weather (petrichor) or when soil is disturbed. The human nose is extremely sensitive to geosmin and is able to detect it at concentrations as low as 5 parts per trillion. Geosmin is found in corn.1,10-Dimethyl-9-decalol11,12,13-Trinor-5-eudesmanol4,8a-Dimethyloctahydro-4a(2H)-naphthalenol4,8alpha-Dimethyl-octahydro-naphthalen-4alpha-olOctahydro-4,8a-dimethyl-4a(2H)-naphthalenol, 9CIC12H22O182.3025182.1670653264,8a-dimethyl-decahydronaphthalen-4a-olgeosmin19700-21-1CC1CCCC2(C)CCCCC12OInChI=1S/C12H22O/c1-10-6-5-8-11(2)7-3-4-9-12(10,11)13/h10,13H,3-9H2,1-2H3JLPUXFOGCDVKGO-UHFFFAOYSA-N belongs to the class of organic compounds known as tertiary alcohols.
