Geographical origin identification of Romanian wines by ICP-MS elemental analysis
Food Chemistry, 2013
Trace elemental analysis, besides its ability to determine stable isotopes ratios, represents a possible complementary tool useful to differentiate wines based on their regional origins. Wines and their provenance soils from two major wine producing areas in Southeast Romania ('Valea Calugareasca' and 'Murfatlar'), and also wine from the region of Moldova (Eastern Romania) were analyzed by inductively coupled plasma mass spectrometry (ICP-MS), and statistical data of elemental composition was used to differentiate these wines according to grape type and geographical origin. Moreover, this study gathers relevant elemental trace composition of wines produced in most important Romanian vineyards, thus offering a useful wine differentiation tool by their production district. The results show that the differentiation of Romanian wines according to their provenance is based on the following main elements: Ni, Ag,
Chemometric prediction of the geographical origin of Croatian wines through their elemental profiles
Journal of food and nutrition research
The inorganic chemical pattern of wine is a reflection of regional soil geochemistry, climate and processing. Elements can be considered as good markers of the geographical origin of wine since they are neither metabolized nor modified during the wine making process [1]. Wine elements concentration depends on several factors such as: grape variety, area of production, soil characteristics , environmental conditions and climate. Their determination facilitates establishment of a " fingerprint " for each element [2], giving an opportunity to develop a link between wines and their geographical origin [3]. If properly developed, a chemically-based independent system of classification would support the " wine origin " identification that is used in all wine-producing countries with a main goal to prevent fraudulent practices in the wine industry [4]. Recently, several studies dealt with determination of geographical affiliation of wines based on their elements composi...

Major, minor and trace elements in wines from Greece were determined by inductively coupled plasma–mass spectrometry (ICP–MS). The concentrations of 44 elements (Na, Mg, P, K, Ca, Cu, Co, Cr, Zn, Sn, Fe, Mn, Li, Be, B, V, Sr, Ba, Al, Ag, Ni, As, Sn, Hg, Pb, Sb, Cd, Ti, Ga, Zr, Nb, Pd, Te, La, Sm, Ho, Tm, Yb, W, Os, Au, Tl, Th, U) in 90 white and red wines from six different regions in Greece for two consecutive vinification years, 2017 and 2018, were determined. Results for the elements aforementioned were evaluated by multivariate statistical methods, such as discriminant analysis and cluster analysis, and the wines were discriminated according to wine variety and geographical origin. Due to the specific choice of the analytes for multivariate statistical investigation, a prediction rate by cross-validation of 98% could be achieved. The aim of this study was not only to reveal specific relationships between the wine samples or between the chemical variables in order to classify the wines from different regions and varieties according to their elemental profile (wine authentication), but also to observe the annual fluctuation in the mineral content of the studied wine samples.

The control of geographic origin is one of a highest priority issue regarding traceability and wine authenticity. The current study aimed to examine whether elemental composition can be used for the discrimination of wines according to geographical origin, taking into account the effects of soil, winemaking process, and year of production. The elemental composition of soils, grapes, musts, and wines from three DO (Designations of Origin) and for two vintage years was determined by using the ICP-MS semi-quantitative method, followed by multivariate statistical analysis. The elemental composition of soils varied according to geological formations, and for some elements, the variation due to soil provenance was also observed in musts and wines. Li, Mn, Sr and rare-earth elements (REE) allowed wine discrimination according to vineyard. Results evidenced the influence of winemaking processes and of vintage year on the wine’s elemental composition. The mineral composition pattern is trans...

Geographical wine traceability is an important topic in the context of wine authentification. Therefore, many researchers have addressed this subject by developing different methodologies based on multivariate analysis of organic and inorganic parameters and also by isotopic signature. The goal of this research was to assess the potential of elemental composition and isotopic signature of lead (207Pb/206Pb, 208Pb/206Pb and 204Pb/206Pb) and strontium (87Sr/86Sr) of wines from three Romanian vineyards, in order to highlight reliable markers for wine geographical origin. The ICP-MS method was used for the concentration determination for 30 elements (Ag, Al, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cs, Cu, Fe, Ga, In, K, Li, Mg, Mn, Na, Ni, Pb, Rb, Se, Sr, Tl, V, U, Zn, Hg). In this study 10 wines (2 red and 8 white) obtained from ‘Merlot’, ‘Fetească neagră’, ‘Fetească albă’, ‘Fetească regală’, ‘Băbească gri’, ‘Șarba’, ‘Aligoté’, ‘Sauvignon blanc’, ‘Muscat Ottonel’, ‘Italian Riesling’ cultivars ...

In this work, the characterization of white and red wines from Austria and Argentina was carried out based on the isotopic and multi-elemental profile data. They were determined using vanguard techniques such as isotope ratio mass spectrometry and inductively coupled plasma mass spectrometry. In particular, Al, As, B, Ca, Co, Cu, Fe, K, Li, Mg, Mn, Na, Ni, Pb, Rb, Sr, V, Zn, δ18O, and δ13C were determined. The results show that the samples of wines from Argentina generally present higher concentrations of the elements analyzed compared to Austrian wines. δ18O values from wine water were characteristic of each country, while δ13C values from ethanol did not present any geographical distinction. Linear discriminant analysis using isotopes and elements allowed us to classify 100% of the wines according to the origin and additionally, 98.4% when separately investigating red and white wines. The elements Sr, Li, V, Pb, B, Mn, Co, Rb, As, Na, Mg, Zn, and δ18O were identified as sensitive ...

Wines from three important wine-producing Southern Italian regions (Basilicata, Calabria and Campania) were characterized according to their content in macro-, micro-elements and lanthanides. The elemental composition was used in multivariate statistical analysis to discriminate the wines according to geographical origin. A total of 61 elements were determined in 120 red wines produced in the years 2000e2002, and precisely 40 samples for each region. Results indicated that element analysis provides a good prospect for discriminating wines by regions, even if the element composition is not dependent on the year of production of wine. A Canonical Variate Analysis showed that the discrimination of wines according to their provenance is based on the following elements:

Climate change is having an increasing influence on vine phenology and grape composition, affecting vinifications, wine chemistry and the quality of productions. Wine grape cultivation provides a good test case for measuring indirect impacts mediated by changes in agriculture, because viticulture is sensitive to climate and is concentrated in Mediterranean climate regions that are global biodiversity hotspots. Moreover, on a regional level and on a shorter time scale, the seasonal weather conditions modify the quality of yields determining the final properties of wine. In the present research, we studied wines from Italy and Slovenia with the purpose of differentiating them by the different vintages, which are supposed to be influenced by temperature and rain during each year’s growing season. Specific chemical techniques were used, in particular mass spectrometry (ICPMS) and isotopic mass spectrometry (IRMS), both of which are usually employed to detect wine adulterations and to es...
