Factors which affect coffee quality.

Following analysis of the chemical factors contributing to reduced quality in coffee, the pre- and postharvest factors influencing quality are reviewed; these include cultivar selection, site, climatic conditions, changes during ripening, incidence of microorganisms, effects of fertilizers, enzymatic and microbial fermentation, storage, mixture of coffee types, and roasting. Finally the effects of roasting on the physical and chemical characteristics of beans and on quality are examined together with the effects of grinding on flavour.
