Mondo Knows Facts
Roasting builds the aroma of coffee
Green beans smell grassy until heat drives browning and hundreds of aromas Raw coffee seeds are dense, pale and smell of hay, and the flavours we recognise appear only after roasting. Between about 200 and 240 degrees Celsius, sugars and amino acids react, organic acids break down and the bean expands and darkens. The roaster must stop the process before the aromatic compounds themselves are burnt away. It sits in Mondo's food collection, one of 200 facts that each trace back to the reference below.
