Rikilt determines coffee's 'finger print'.
Clear difference between organic and normal coffee.
The researchers extracted the air from a bottle containing half a gram of coffee. A so-called mass spectrometer determined exactly which aromas were present. Coffee can release about 900 different aromas and each of these has its own profile, which can be likened to a finger print. It turned out that it is easy to distinguish between organic coffee and normal coffee in this way. The differences arise because organic coffee is cultivated differently, without pesticides and with natural manure.
