Wine is an extremely sophisticated chemical matrix in which the harmonious equilibria between many components (alcohols, acids, aromas, polyphenols, etc.) determine its final quality and value. The study of wine composition by metabolomic tools, referred as Wineomics, has emerged as a revolutionary approach to unravel the chemical space of wines and to associate wine composition with important viticultural and enological traits including grape variety, geographical origin, terroir or typicity. One of the most promising applications of metabolomic tools for wine analysis is the study of wine traceability and authenticity, a major issue for the wine industry and consumers. These studies are extremely complex, because counterfeits are becoming more sophisticated and they require powerful techniques capable to detect subtle differences between wines. In this chapter, we describe the targeted and untargeted approaches by Mass and NMR spectrometry-based metabolomics as well as some recent examples of their abilities in wine authenticity studies.< Leer menos
