Roast Profile refers to the relationship between time and temperature in coffee roasting, with the endpoint being the “degree of roast”. Roast profiling is the active manipulation of the “roast curve” or graphed plot of bean temperature during the roast, to optimize the results in terms of flavour. Two batches might be roasted to the exact same degree of roast, temperature endpoint or time, and have very different cup results due to different roast profiles. It’s not just important how dark a coffee is roasted, it is equally important how it got there, and that is expressed in the roast profile.
