This research investigates the influence of two roasting parameters—colour (i.e., roast degree) and time—on coffee flavor, using sensory descriptive analysis. Results from eight studies indicated that roast colour was the stronger predictor of coffee flavour. Darker roasts/longer roasting times were associated with an increase in bitterness and a decrease in acidity, fruitiness, and sweetness. With respect to roasting time, we distinguished two phases, “time to first crack”, corresponding to the time between the onset of roasting and the moment where the accumulated steam pressure causes the beans to crack, and “development time”, corresponding to the time elapsed from the first crack to the end of the roasting process. The results clearly indicated that, keeping colour constant, development time had the largest effect on coffee flavour.
