In this study, Marwani E. and team unraveled how geographical origin and climate factors shape the volatile metabolite profiles of Robusta green coffee beans from five major regions in West Java. Through SPME-GC-MS analysis, they identified 143 volatile compounds, with aromatic hydrocarbons, alcohols, and terpenes as the dominant groups. PCA revealed that Bogor beans had a distinct profile compared to beans from Ciamis, Kuningan, Sumedang, and Tasikmalaya. Key discriminant metabolites included benzaldehyde, isovaleric acid, and caffeine, whose levels correlated with temperature, rainfall, and altitude. This research highlights the chemical diversity of West Java’s Robusta coffee and the strong link between environmental conditions and bean quality.
