The study of terroir, increasingly popular in scientific circles, remains a challenging field, particularly in terms of sensory analysis. This paper summarizes our own contribution to the field-an approach for tracing the typicity of wines by sensometrics, using the Malbec variety as a case study. This large-scale research fingerprinted 81 wines fr...

The sensory and phenolic profiles of Cabernet Franc wines from different geographical indications (GIs) of Mendoza, Argentina, were studied for the first time. Different statistical methods showed that it is possible to discriminate wines of different GIs by aroma and taste descriptors. In terms of phenolic composition, anthocyanins showed higher r...

The chemical and sensory characteristics of the wines are related to the geographical origin of the grape, as a result of the interplay between the plant material (G), its acclimatization to the environment (E) and the human factor that influences both the vineyard and the winery. The range of phenotypes that a single genotype can express depending...

This study evaluated the phenolic profiles of Malbec wines made from grapes of 23 parcels distributed in 12 geographical indications (GIs) from Mendoza, Argentina. Wines were elaborated under standardized winemaking conditions over three consecutive vintages (2016–2018). Data discriminated wines from different GIs and parcels, based on an integrati...

Los viñedos de Mendoza se encuentran en cinco zonas que corresponden a los distintos oasis productivos y en ellas existen Indicaciones Geográficas (IG), para identificar los productos originarios de cada localidad, con diferente reputación, calidad, y características. El Cabernet Franc es un cultivar que en Argentina se encuentra presente en todas...

The most reputed vineyards in Mendoza, Argentina, are located in the Uco Valley and Luján de Cuyo, regions with different altitudes (900-1500 m asl), soil types and temperatures. The winemaking quality is associated with the concept of terroir, including environmental factors and plant material (genotype). The aim of the present study was to evalua...

Malbec wines from 27 parcels from the three most important winemaking regions of Mendoza, Argentina, were produced under standardized winemaking conditions, and analyzed for phenolic composition and by means of sensory descriptive analysis. Different methods of characterization and cluster analysis for each data matrix showed that some locations of...

The quality of grapes and wines depends on the "terroir", a concept that in the simplest sense refers to the effects of plant material, environmental factors and canopy management. Therein, the soil characteristics have been described as a key factor. In this study, grapevines and wines from two contrasting alluvial soils, rocky shallow (shallow) a...
