COFFEE IS A GLOBALLY IMPORTANT CROP WITH A COMPLEX SUPPLY CHAIN SUPPORTING OVER 20 MILLION FAMILIES WORLDWIDE. IN 2018, GLOBAL COFFEE PRODUCTION WAS ESTIMATED AT 160 MILLION BAGS OF GREEN COFFEE, BUT THE GLOBAL AVERAGE COFFEE MARKET PRICE HAS RECENTLY DROPPED TO ITS LOWEST LEVEL SINCE 2005. IN ADDITION, COFFEE IS IDENTIFIED AS A CLIMATE SENSITIVE SPECIES AND RESEARCH SUGGESTS THAT BY 2050 THE LAND CURRENTLY UTILIZED FOR COFFEE GROWING WILL SHRINK AN ESTIMATED 38% TO 90%. GIVEN THESE ECONOMIC AND CLIMATIC PRESSURES COFFEE PRODUCERS ARE FACING A SEVERE CHALLENGE LEAVING THEM VULNERABLE AND AT RISK OF BEING FORCED OUT OF THE SECTOR. ONE WAY FOR COFFEE PRODUCERS TO INSULATE THEMSELVES FROM THESE CHALLENGES IS TO DIFFERENTIATE IN THE MARKET AND PRODUCE SPECIALTY, HIGH QUALITY, AND ENVIRONMENTALLY FRIENDLY COFFEES. HOWEVER, THE LINKS BETWEEN THE ENVIRONMENT, AGRONOMICAL PRACTICES, AND THE CHEMICAL AND SENSORY QUALITY OF COFFEE IS NOT FULLY UNDERSTOOD. FIRM LINKAGES BETWEEN AGRONOMICAL PRACTICES AND QUALITY WOULD ALLOW FARMERS TO INFORM THEIR STRATEGY IN THE FUTURE AND CONTRIBUTE TO A MORE SUSTAINABLE COFFEE VALUE CHAIN.THIS PROJECT AIMS ADVANCE OUR FUNDAMENTAL UNDERSTANDING OF COFFEE PLANT HEALTH, PRODUCTION, AND SUSTAINABILITY WITHIN THE CONTEXT OF EXAMINING THE AGRICULTURE SYSTEM FROM SEED TO CUP. A FURTHER UNDERSTANDING OF THE RELATIONSHIP BETWEEN FARMING MANAGEMENT, GREEN COFFEE METABOLITES, AND THE SENSORY CHARACTERISTICS WILL ALLOW FOR PRODUCTION OF A DIVERSIFIED COFFEE PRODUCT. THE RESULT WILL ESTABLISH HOW DESIRABLE SENSORY CHARACTERISTICS ARE RELATED TO THESE FARM-LEVEL ADAPTATIONS. THIS WILL BE COMPLETED BY USING MASS SPECTROMETRY TO PROFILE THE CHEMICAL FINGERPRINT OF SHADE-GROWN AND MONOCULTURE SUN-GROWN COFFEE, EACH FARMED IN AN OPTIMAL AND SUBOPTIMAL COFFEE-GROWING REGION OF COSTA RICA. DESCRIPTIVE ANALYSIS WILL CAPTURE THE QUANTITATIVE SENSORY PROFILE AND HEDONIC MEASURES WILL BE USED TO EVALUATE THE PURCHASE INTENT OF COFFEE ROASTERS. RESEARCH CONCLUSIONS CAN BE APPLIED TO MULTIPLE LEVELS OF THE COFFEE SUPPLY CHAIN, WITH EMPHASIS TOWARDS PROVIDING FEEDBACK TO COFFEE FARMERS.
