Relação custo x características físico-químicas e sensoriais de vinhos cv. tannat, safra 2013/2014, oriundos do Uruguai e da região da campanha do Rio Grande do Sul

Abstract

The Campanha region is situed in the southwest of Rio Grande do Sul, near the border with Uruguay, the country dedicated for the production of great Tannat wines for its favorable terroir, making this culture to expand increasingly in this region. But the fact bordering Uruguay, brings harm to the Gaucho wine, since imported into the country without fees and taxes, and the consumer still has a mistaken view of the national product, believing that imported wine has more quality the national. The variety Tannat is an iconic vitis vinifera grape of Uruguay and has also highlighted the Gaucho Campaign, resulting in full-bodied wines of excellent color, aromas and, if well processed, provides a very balanced wine on the palate, with regard to the acidity and astringency, different from other Tannat wines produced in Brazil. The Tannat wines produced in the campaign in the region are often compared with those produced in Uruguay, due to the proximity of regions and similar climatic features. Thus, physicochemical and sensory characteristics of eight samples were analyzed wine purchased in local shops, four Uruguayan and 4 of the Campaign Region, in order to analyze the potential of this cultivar to produce varietal wines in relation to price. It was found that as much as sensory analysis and physical-chemical analyzes, the price affect the results, and samples with higher added value excelled in most of the variables analyzed. In the sensorial analysis, the preference of the judges was one of the samples of the Campaign Region. Already in the physical and chemical analysis, the samples showed different results statistically in virtually every parameters analyzed however, there was no direct relationship between quality and price parameters. Thus, further study of the regions and cultivate Tannat is necessary in order to evaluate the characteristics of wines produced in subsequent crops.
