Characterization of the aromatic profile of Ruché wine from Piedmont (Italy) with gas chromatography–mass spectrometry and unsupervised machine learning techniques

The volatile composition of Ruché, a red wine produced from a native grape in Piedmont (Italy), was investigated using headspace-solid phase microextraction (SPME) coupled to gas chromatography-mass spectrometry (GC/MS). The main volatile compounds of the wine were identified and quantified. Chemometric techniques were applied to identify features and possible clusters among the different samples.
