Frequently asked questions


In a practical and simple way, the ABG Color System guides coffee roasters in the search for a pattern in their roasting. By making comparisons between different scales and denominations already known, the roasters can make the analysis through the color spectrum of the scale and the roasted, ground, and compacted coffee.

ABG COLOR SYSTEM serves to measure the color of the coffee after roasting, as well as the repeatability of the roasting pattern.
It has an important commercial role for roasters that sell to consumers who increasingly look for information and knowledge on the subject.

The scale is also very useful for educational purposes. With an increasing consumer demand for quality coffees, the roasting point is a crucial issue. And roasters, coffee shops, courses and workshops can demonstrate in a didactic way the differences between the types of roasting and their implications for the quality of good coffee.

How to use?
  • Coffee must be ground and have a maximum particle size of 340 microns (1 micron = thousandth part of 1 mm), which is the grind for espresso. Too fine grind is not recommended because the particle becomes hygroscopic, that is, it absorbs moisture from the air very easily, changing its color perception.  Coarser grinding does not maintain uniformity of particles and impairs color perception.
  • Compact the ground coffee with the tamper to assure a uniform surface for the reflection of light.

  • Ground coffee compacted in the dishes should be close to the edge, that is: keep the dish full. The closer to the surface, the better the comparative view will be.

  • Make comparative reading or visualization in a well-lit place, preferably with indirect natural light. Direct natural light will impair color perception. Example: make the comparison next to a window.

  • With artificial light, these should be the lamp specifications: Daylight Special, IRC (Color Rendering Index) better than 90%, and a guarantee of at least 400 lumens on the color scale surface.
How accurate is the color evaluation?
  • Important: For a high precision evaluation it is essential that the verification is done in specific equipment, known as a reflectance colorimeter.

  • The ABG Color System uses comparative visualization, and its results are considered remarkably close to those obtained in the most sophisticated equipment, if the evaluation conditions are correctly fulfilled.

  • It is useful for small roasters and cafeterias, and for domestic use.

  • Its use is prohibited for research purposes or for issuing technical reports, due to the interpretive capacity of each user.
