| Sumario: | Argentina is an important worldwide wine producer. In this country, there are several recognizable provinces
that produce Sauvignon blanc wines: Neuquén, Río Negro, Mendoza, and San Juan. The analysis of the provenance of
these white wines is complex and requires the use of expensive and time-consuming techniques. For this reason, this work
discusses the determination of the provenance of Argentinean Sauvignon blanc wines by the use of UV spectroscopy and
chemometric methods, such as principal component analysis (PCA), cluster analysis (CA), linear discriminant analysis
(LDA), and partial least square discriminant analysis (PLS-DA). The proposed method requires low-cost equipment and
short-time analysis in comparison with other techniques. The results are in very good agreement with results based on
the geographical origin of Sauvignon blanc wines. |
