Fingerprints for main varieties of argentinean wines: Terroir differentiation by inorganic, organic, and stable isotopic analyses coupled to chemometrics
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 varietie...

Chemometrics allowed robust differentiation between regions, wine varieties, and the same variety from different regions.
