Cover Story: mass spectrometry (IRMS) and nuclear magnetic resonance (NMR) spectroscopy, is revealed to be a useful tool for the characterization, confirmation, and promotion of high-quality PDO olive oils. As an example, Italian “Colline Pontine” PDO olive oils (Lazio region) of consecutive crop years were investigated using the proposed protocol, and the results, elaborated by statistical analyses, allowed the identification of specific sensory and chemical markers.
