High-throughput oenomics: shotgun polyphenomics of wines.


Red wine is a complex mixture of organic compounds including polyphenols and the use of ultra high performance liquid chromatography-electrospray ionization-quadrupole-time-of-flight-mass spectrometry (UHPLC-ESI-Q-TOF-MS) is a promising technique to better understand its quality and authenticity. To optimize the characterization of red wine, we developed an original and fast method that represents the first shotgun polyphenomics analysis of wine. We show that our new method yields significantly more information than previous fast methods such as direct injection-ESI-MS of wine, with the identification of 103 compounds in 2 min. As a first application, we show that the use of a specific selected ion ratio demonstrates significant differences between Pinot Noir, Merlot, and Syrah wine spectra in a preliminary study.
