Effects of climate and anthocyanin variables on the zoning of Pinot Noir wine from the Casablanca Valley
The Casablanca Valley is one of the youngest wine grape regions of the Chilean appellation of origin. The growers of this area note the presence of microclimates within the valley as one of its main features. These microclimates have historically been associated with two geographical
zones: the Zona Alta and the Zona Baja. The objective of this research was to explore the effects of climate variables and anthocyanin profiles in Pinot Noir wines of the Casablanca Valley as a differentiator of productive zones. The climate variables were measured using weather stations located
at different points across the valley. Wine samples from the same locations were characterised according to their anthocyanin profiles. The data were processed using analysis of variance, principal components analysis and partial least squares discriminant analysis to determine differences
between the two groups explored. The results indicate a strong correlation between variables and zones (98.3% R2Y), leading to the conclusion that there are significant differences between the Zona Alta and Zona Baja group. Finally, the existence of a vineyard that does not belong
to the Zona Baja group suggests a reassessment should be performed of the vineyards belonging to the administrative areas defined as part of the Casablanca Valley.
