But how do we know what color indicates what roast style a bean is? Lucky for you, we’ve been doing this for a long time so we can look at a bean and identify its roast in the blink of an eye. We also have what’s called an Agtron machine to help us make faster (and maybe even a little more accurate) identifications. An Agtron machine reflects near-infrared light on a sample of coffee to analyze and assign a number to the beans' roast color. The larger the number, the lighter the roast. We have found certain numbers that match our taste preferences, and then we use the machine to get as close to perfection as we possibly can.
