Roast profiles regarding the flavor

Different roasting profiles should be applied to green coffee beans, whose characteristics are known, to discover their aromas. Roast profiles should be created regarding slow, fast and optimum roasting parameters.

Duration and temperature of roasting, volume and pressure of the hot air, and the burner capacity should be changed, and resulting profiles should be recorded. In order to achieve the best result, roasting processes may be changed, if need be.

These profiles and the tasting notes are evaluated together and new profiles shall be created. Green coffee beans of the same origin shall be roasted in different profiles regarding the changes in production year, storage, moisture content, etc.
