Global Arabica coffee trials show the complex influence of genetics and climate on quality

After sensory testing of ten coffee varieties in seven regions of the world for three years (between 2021 and 2023), researchers from World Coffee Research (WCR) demonstrated how the interaction between genotype and environment impacts the quality and flavor profile of the coffee. drink. At the same time, they want to refine the test, removing factors such as post-harvest and roasting from the equation, which interfere with the drink's sensorial properties. The first results of the largest variety test in the world, according to the scientific institution itself, were released in June. The objective is to understand the scope of these interactions between DNA and growing conditions, so that this information can help participating countries define varieties with greater quality potential. Furthermore, the results will serve as a basis for new quality experiments. The research is part of the International Multilocation Variety Trial or IMLVT project, which tests 31 high-performance ...
