Malbec wines from 27 parcels from the three most important winemaking regions of Mendoza, Argentina, wereproduced under standardized winemaking conditions, and analyzed for phenolic composition and by means ofsensory descriptive analysis. Different methods of characterization and cluster analysis for each data matrixshowed that some locations of Mendoza could be significantly separated from each other. The results of unsupervised statistical methods were compared using a test for similarities and divergences, also showing thatdifferent locations may be associated. The current report is the first one characterizing Malbec wines from thethree major producing regions of Argentina using two different ways for locations classification. The effects ofclimate and geographical origin of Malbec grapes on the quality parameters of resulting wines were also evidenced. These results have enological and viticulture interest for the winemaking industry as the vineyard siteselection for Malbec can considerably affect quality attributes.
