What is coffee roasting color analysis?
Along with tasting your coffee, the most effective tool in analyzing the degree of roast, especially for consistency, is a color meter. This tool gives a specific number for the color that coffee is roasted to. Best practice for using this tool is to measure the color of the whole bean coffee and then measure the color of the same coffee, but ground. This gives you two numbers and shows a comparison of those numbers.
For example (hypothetically, and keep in mind, the higher the number the lighter the roast:) My standard roast for breakfast blend is “58” for whole-bean and “67” for ground. I can give myself a +/- deviation of 1.5 points. If I measure a roast of my breakfast blend at “58” whole-bean but the ground measurement is “70,” I know that my roast went too quickly, the coffee did not roast through well enough meaning it was likely too fast of a roast. I may want to cup it now and make sure that the profile is not too far out of spec to sell the coffee as “Breakfast Blend.”
Having a reliable tool that gives you concrete, measured, clear information about your coffee is vitally important to running a consistent and reliable coffee roasting program. Find the right color meter to fit your needs below.

Javalytics Desktop Color Analyzer
The JAV-RDA-U measures traditional degree of roast darkness. The JAV-RDA-U views samples through the bottom of an optically flat dish. You can choose to run from the built in touch screen LCD display or from the optional PC network connection. The touch screen LCD display is the simplest human interface available: an incredibly easy to read, high contrast, and bright blue liquid crystal display, with touch screen operation.
It could not be easier, simply touch the screen with a finger. Operating from a computer, using the optional network software control (JAV-NET), allows the user to input several definable variables (operator, country of origin, roast, etc) and saves data in a comma separated value file with a time and date stamp for each sample.
