  abstract = {{BACKGROUND} {T}he effects of the environment and genotype in the coffee bean chemical composition were studied using nine trials covering an altitudinal gradient [600-1100 m above sea level (a.s.l.)] with three genotypes of {C}offea arabica in the northwest mountainous region of {V}ietnam. {T}he impacts of the climatic conditions on bean physical characteristics and chemical composition were assessed. {RESULTSW}e showed that the environment had a significant effect on the bean density and on all bean chemical compounds. {T}he environment effect was stronger than the genotype and genotype-environment interaction effects for cafestol, kahweol, arachidic ({C}20:0), behenic acid ({C}22:0), 2,3-butanediol, 2-methyl-2-buten-1-ol, benzaldehyde, benzene ethanol, butyrolactone, decane, dodecane, ethanol, pentanoic acid, and phenylacetaldehyde bean content. {A} 2 degrees {C} increase in temperature had more influence on bean chemical compounds than a 100 mm increase in soil water content. {T}emperature was positively correlated with lipids and volatile compounds. {W}ith an innovative method using iterative moving averages, we showed that correlation of temperature, vapour pressure deficit ({VPD}) and rainfall with lipids and volatiles was higher between the 10th and 20th weeks after flowering highlighting this period as crucial for the synthesis of these chemicals. {G}enotype specific responses were evidenced and could be considered in future breeding programmes to maintain coffee beverage quality in the midst of climate change. {CONCLUSIONT}his first study of the effect of the genotype-environment interactions on chemical compounds enhances our understanding of the sensitivity of coffee quality to genotype environment interactions during bean development. {T}his work addresses the growing concern of the effect of climate change on speciality crops and more specifically coffee.},
