PUC Pontificia Universidad Católica de Chile, Departamento de Fruticultura y Enología, Chile
13 clonal selections of cv Cabernet Sauvignon, established in Nancagua VI Region, Chile (34.39 °S 71.17 °W). The genetic identity of the vines was confirmed by ampelography and microsatellite markers (SSR). Evaluations in the 2012–2013 season include: performance, analytical and sensorial parameters on the wines made by microvinification. The results were statistically analyzed with the Statgraphics Plus program and multiple comparison test of Tukey at 95% confidence level. Sensorially, the wines were evaluated by a panel of 12 experts. The results were likewise analyzed by testing principal components (PCA) with covariance matrix without rotation. In the season studied the selection 108 highlighted with a high yield (kg/plant), in the composition of the wine selections generally highlighted for contents of total polyphenols and anthocyanins over average. The results show typical sensory characteristics of wines from that grape variety, and it was possible to group the selections by their attributes (PCA) with cherry red wines at different intensities, but without significant differences, with fruity and vegetal aromas, interesting complex flavors and with structured tannins.
