This article presents a preliminary study on the analysis of samples of Colombian coffee for the detection and classification of defects (i.e. using "Cup Tests"), which was conducted in Almacafé quality control laboratory Almacafé in Cúcuta, Colombia). The results obtained show the application of an Electronic Nose (EN), called "A‐NOSE," used in the coffee sector for the cupping tests. The results show that e‐nose technology can be a useful tool as quality control of coffee grain.
