ROAST DEGREE AND COLOR
Roast degree is the term used to describe the overall level of, "doneness" of a batch of roasted coffee.
However, because the physical and chemical properties of green coffee beans vary, as well as the time and temperature parameters employed in roasting specific profiles, the color of the roasted beans only represents ,"doneness" relative to the specific roast profile, as it is defined.
Two identical green coffee bean samples can be roasted to the same color, but have dramatically different physical characteristics, most notably in bean size, pore size and pore volume, by simply changing the temperature and time parameters.
Color is simply the most practical gauge of how complete the specific roast is.

Whole roasted beans were run for three consecutive 20 second scans. The sample was then roughly ground, and run for three consecutive 20 second scans.
HERE'S THE DIFFERENCE
Colortrack is part of a new wave of laser technology breakthroughs, made possible by pc based data acquisition hardware and software. The ColorTrack Laser Module transmits and receives some 10,000 individual readings in a one second scan. Since the recomended scan time is 20 seconds, that leaves about 200,000 readings to be analyzed per test.
The unique signal generated by the laser module, operates specifically in the 785 nanometer range of the color spectrum, which is the optimum range for detection of shade differences, and never before available on a color analyzer.
The combination of the type of signal, and the dramatically increased sample size, have provided an instrument capable of analyzing roasted coffee color, in ways never before imagined. It may be possible in time to eliminate the grinding and other sample preparation procedures altogether.

Winner of the SCAA Best New Product Open Class 2009, the benchtop ColorTrack takes 200,000 readings in a 20 second scan. The results are delivered to a pc, including graphical representation, and a comprehensive statistical breakdown, including the average reading, mode, median, and standard deviation. Profiles can be saved as a file for storage or export.
