Brazil is the largest producer of sacks of green coffee beans, and the Brazilian population is the largest consumer of coffee beans in the world. Several parameters make this drink so appreciated by the consumer, highlighting the sensory characteristics and its stimulating effect, which is caused by the presence of caffeine. In this sense, the stage of grains reception is fundamental because it is where the grains are selected and important chemical changes that give the coffee the flavor, aroma and peculiar color can occur in its processing. Coffea arabica (Coffea canephora) and Coffea canephora (Coffea conillon) are the most widely used coffee roasters in the world, due to their high yields and good industrial yields. For this work, 300 g of 20 lots, 15 lots of arabica coffee and 5 lots of conilon coffee were collected, where the separations were made by types of intrinsic and extrinsic defects and coffee classification, according to Normative Instruction no8, of June 11, 2003, Technical Regulation of Identity and Quality for Classification of Granted Raw Coffee. The main defects identified in the coffee bean lots distributed to companies in the rural state of Pernambuco were grains of the following types: black, burnt, green, broken, ladle, pomegranate, barley, impurities (bark, stone, stick and clod). Finally, grain grading results show that the most recurring defect in arabica coffee samples is green grains followed by broken grains, and in the conilon coffee samples the main defects were green, burned and broken, thus receiving classification 8. Greater control should be taken at this stage, in order to have a better classification of coffee, the best product to the consumer associated with a good industrial yield.
