What is it about?
In this study, ten different varieties of Coffea arabica L., were cultivated with irrigation and no irrigation regimes and these samples were analyzed by direct infusion electrospray ionization mass spectrometry (ESI-MS), in positive mode.

Why is it important?
The cup test showed that the coffees cultivated in not-irrigated regime had slightly larger cupping notes that the ones cultivated under irrigation, probably because they presented higher sucrose content.
Perspectives
It was possible to efficiently sort the groups of irrigated and non-irrigated using PLS-DA to obtain all the minimum requirements for evaluation of efficiency of the rating model. Sucrose and the ion m/z 431 (not identified) suffered a negative influence of irrigation. The trigonelline, and the ion m/z 723 (not identified) were influenced positively by irrigation.
