    International markets are increasingly signaling demand for quality-differentiated coffee, which the Colombian Coffee Growers Federation (FNC) proposed to exploit to identify those regional coffees that would fulfill the requirements to be classified as denomination of origin. The objective of this study was to develop and implement a sound, robust and repeatable approach with and for the FNC to identify regional causal relationships between coffee quality and environmental characteristics as bases for labels of denomination of origin. Environmental differences between coffee-growing areas in the departments of Cauca and Nariño were statistically significant for several characteristics, including the number of dry months, annual precipitation and diurnal temperature range. The dominant varieties (Caturra and Colombia) did not show major differences in quality attributes, and were pooled for the analyses with the environmental data. There are significant differences in biochemical and sensorial product characteristics between the two departments. The spatial patterns in product characteristics exhibit a non-random, regionally-changing structure that is related to those in the environmental data. The generated results provided ample evidence to support the application for regionally-based denominations of origin. Recommendations were derived to help mainstreaming the developed approach and thereby facilitate policy decisions for its use in other geographies and with other crops. Furthermore, the importance of systematic interdisciplinary institutional collaboration for large-scale denomination of origin projects was corroborated for food policy dialogue and decision making. It seems plausible that producers of high-quality products within other commodities are likely to follow the FNC in seeking denomination of origin for their goods. The presented approach is crucial to facilitate policy.
