Discrimination by advanced spectroscopic techniques of wines aged in cask from those obtained through the use of alternative woods, in order to protect the consumer, the quality and typicality of Piedmontese wines
The search for tools capable of detecting fraud in the agri-food sector, and in particular in the oenological sector, is made urgent by the dizzying increase in cases of counterfeiting and “wine-piracy” which we are witnessing in recent years, a phenomenon that threaten the incomes of thousands of small producers as well as damaging the image of a fundamental sector for the Piedmontese and national economy such as the wine sector.
Recent research has highlighted the possibility of discriminating wines based on the type of refinement (chips or barriques) through spectroscopic techniques combined with chemometric methods. The combined application of more traditional and reproducible analytical techniques such as GC-MS and NMR, flanked by portable and low-cost techniques, such as NIR spectroscopy, constitutes an important opportunity to evaluate complementary methods of investigation to be applied to the classification of products obtained from the aging of the wines in barrique from those obtained with the use of chips, for the protection of the quality of Piedmontese wines.
The aim of the research is therefore to recognize wines obtained with production or aging techniques other than those possibly declared. The project intends to explore the possibility of achieving this goal by integrating multiple and integrated analytical approaches such as mass spectrometry combined with gas chromatography, IR spectroscopy and above all 1H-NMR spectroscopy.
