The objective of this work was to analyze the coffee quality by using the spatial correlation. The work was done in the 2004 and 2005 harvesting seasons at Brauna Farm, located in Araponga, Minas Gerais state, Brazil. Coffee quality maps were generated. From the quality maps, the spatial autocorrelation analyses were performed by using the Moran Index. The results obtained indicated that the coffee quality has spatial dependence.
