Abstract: Coffee is a major source of foreign currency of Timor-Leste and is the primary source of income for about one quarter of the population. This study characterized the Ermera’s coffee and assesses the impact of soil and climatic conditions and post-harvest technology especially in physical and organoleptic characteristics of green coffee. In the first part of the work, I was accompanied the post-harvest technology practiced by the companies and farmers, picking up 13 samples. Proceeded to the physical analysis of green coffee (weight of 100 grains, bean size, defects and humidity), roasting and sensory analysis. Also evaluated the effect of roasting by the change in volume and weight, color, defects, acidity and moisture content. Concluded that most samples can be classified in the higher classes for export due to high mass values (14.6 and 19.5 g/100 grains) and coarse-grained (17-20 sieves) and low number of defects. In sensory analysis, detected the bitterness is medium, due to presence of “Híbrido Timor”. The samples prepared by the traditional method stood out mainly due to contain a greater number and variety of defects, although this has not been reflected in the organoleptics characteristics. It was not possible to draw conclusions about the effect of fermentation and mechanics un-mucilage. The characteristics of the samples are more related to the production region, which are dependent on the characteristics of cherry and processing.
