    •Multi-elemental fingerprinting can be used for determination of geographical origin of hops.•The most significant parameters in the discrimination were Si, Ti, Fe and Sr.•Effective differentiation between European and non-European was achieved. For brewers, it is important to know the geographic origins of the hop plants (Humulus lupulus L.) used in their brewing processes since the contents and compositions of the bitter resins and essential oils in them depend on the environmental conditions during their growth. In this study, the multi-elemental profiles of hop plants from each of the world’s main growing regions were determined by non-destructive energy dispersive X-ray fluorescence spectrometry (EDXRF). Understanding the multi-element profiles of the plants could be a useful tool in determining the geographic origins of produced hop plants.
