Fingerprints for Main Varieties of Argentinean Wines: Terroir Differentiation by Inorganic, Organic, and Stable Isotopic Analyses Coupled to Chemometrics

Abstract: Our main goal was to investigate if robust chemical fingerprints could be developed for three Argentinean red wines based on organic, inorganic, and isotopic patterns, in relation to the regional soil composition. Soils and wines from three regions (Mendoza, San Juan, and Córdoba) and three varieties (Cabernet Sauvignon, Malbec, and Syrah) were collected. The phenolic profile was determined by HPLC-MS/MS and multielemental composition by ICP-MS; (87)Sr/(86)Sr and δ(13)C were determined by TIMS and IRMS, respec… Show more

“…Although this technology has been available for more than 10 years, the use of CCT for elemental analysis of wine has been scarce until recently [15][16][17]. The common strategy is based on the use of different sets of conditions for determining spectrally interfered and non-interfered elements, respectively.…”

“…In Argentina, different chemometric procedures have been applied in order to establish quality criteria, genuineness and geographical and varietal differentiation in wine (Fabani, Arrúa, Vázquez, Diaz, Baroni & Wunderlin, 2010;Bentlin, Pulati, Dressler, & Pozebon, 2011;Di Paola-Naranjo et al, 2011;Fanzone et al, 2012), but none of them have applied the spectroscopy methods mentioned above.…”
