Coffee is the most widely traded tropical agricultural commodity in the world with global production for 2016 of over 151 million 60‐kg bags, according to the International Coffee Organization. Such popularity and its chemical complexity demand the development of analytical chemistry methodologies for the characterisation of different coffee compounds. This paper proposes the use of time‐of‐flight secondary ion mass spectrometry (ToF‐SIMS) for this purpose. The main steps involving sample preparation and spectra acquisition are described alongside initial multivariate analysis results.
