“…A complex characterization of wine chemical composition may provide key specific markers for wine origin differentiation (Almeida and Vasconcelos 2003). In this regard, fingerprinting techniques using multivariate approaches have the potential to guarantee the geographical provenance of wine (Saurina 2010;Drivelos and Georgiou 2012;Monakhova et al 2014;Camin et al 2015;Azcarate et al 2015).…”

Wine geographical traceability is an important topic in the context of wine authentication and for that, many researchers worldwide have addressed this subject by developing different methodologies based on multivariate analysis of natural chemical composition data (inorganic or organic parameters) and isotopic signature. The goal of this work was to assess the potential of elemental composition and strontium isotope ratio ( 87 Sr/ 86 Sr) of wines from important wineproducing regions in Romania, located in relatively small geographical areas, in order to highlight reliable markers for wine geographical origin discrimination. Elemental profile determinations were performed by ICP-MS, GFAAS, and FAAS techniques after microwave acid digestion of the wine samples. The 87 Sr/ 86 Sr isotope ratio of the resulted extracts was determined by quadrupole inductively coupled plasma mass spectrometry (Q-ICP-MS), after separating strontium and rubidium using cation-exchange chromatography with Dowex 50W-X8 resin and the complexation ability of the carboxylic acid EDTA. The variation of elemental composition (Ga, Sr, and Al), Ca/Sr ratio, and the 87 Sr/ 86 Sr ratio of the investigated wine clearly demonstrated that these variables are suitable tracers for wine geographic origin determination. The proposed methodology allowed a 100 % successful classification of wines according to the region of provenance.

“…Except for phenolic compounds, other metabolomic data such as volatile compounds or minerals are also used in wine sample differentiation with different detecting techniques, such as GS‐MS and ICP‐MS (Springer and others ; Versari and others ; Azcarate and others ; Cozzolino ; Gambetta and others , ; Roberts and Cozzolino ; Ziółkowska and others ). Besides, the robust wine authentication ability of electronic nose, visible and near‐infrared spectroscopy, and mid‐infrared spectroscopy were also reported in previous studies (Cozzolino and others ; Cozzolino and others ; Bevin and others ; Bevin and others ; Cynkar and others ).…”

“…Researchers report that with the help of multivariate statistical tools, wines of different varieties, regions, and vintages can be differentiated according to their phenolic features (Rastija and Srečnik ; Jaitz and others ; Galgano and others ; Serrano‐Lourido and others ; Pavloušek and Kumšta ; Salvatore and others ; Rubert and others ). Besides, other metabolomic compounds, such as volatiles and minerals, have also been used in wine differentiation (Springer and others ; Versari and others ; Azcarate and others ; Cozzolino ; Gambetta and others , ; Roberts and Cozzolino ; Ziółkowska and others ).…”

To develop a robust tool for Chinese commercial wines' varietal, regional, and vintage authentication, phenolic compounds in 121 Chinese commercial dry red wines were detected and quantified by using high-performance liquid chromatography triple-quadrupole mass spectrometry (HPLC-QqQ-MS/MS), and differentiation abilities of principal component analysis (PCA), partial least squares discriminant analysis (PLS-DA), and orthogonal partial least squares discriminant analysis (OPLS-DA) were compared. Better than PCA and PLS-DA, OPLS-DA models used to differentiate wines according to their varieties (Cabernet Sauvignon or other varieties), regions (east or west Cabernet Sauvignon wines), and vintages (young or old Cabernet Sauvignon wines) were ideally established. The S-plot provided in OPLS-DA models showed the key phenolic compounds which were both statistically and biochemically significant in sample differentiation. Besides, the potential of the OPLS-DA models in deeper sample differentiating of more detailed regional and vintage information of wines was proved optimistic. On the basis of our results, a promising theoretic design for wine authentication was further proposed for the first time, which might be helpful in practical authentication of more commercial wines.

“…Коммерческая ценность вина определяется не только его химическими [1] и органолептическими характеристиками, но и географическим наименованием. Успешное при-менение принятых схем классификации в соот-ветствии с географическим происхождением су-щественно повышает цену продуктов, ассоции-рующихся с определенной страной или регионом и имеющих устойчивую репутацию [2].…”
