| The components and methodology for characterization of terroir was portrayed by Gómez-Miguel and Sotés (1993-2015, 2003) and Gómez-Miguel (2011). This approach is based on a Geographical Information System (GIS) which puts together data form environmental agents (climate, lithology, vegetation, topography, soils, altitude, slope...), data from landscape variables inherited from sensing remote, aerial photo interpretation and a digital elevation model (DEM), and data from grapevine growing management practices (orientation, variety, phenology stages, productivity, grape quality). It allows to analyze both statistics of every variable and their spatial distribution to accomplish a parametric quantification of the variables, to understand how each different variable have influence on the terroir characterization, and, eventually, it shows up the most significant variables. Campo de Borja?s Appellation (DO Campo de Borja) is spread over 65,296.2 ha in the northeast of Spain which includes 6,242.89 ha (2014) of vineyards. Integrated Terroir Zoning (ITZ) of this Appellation has been developed under 1:25,000 scale at different steps: a) stablishing the set of variables that describes the terroir; b) delineating and describing the Homogeneous Terroir Units (HTU); and c) performing the definite ITZ and its validation through the integration of HTU with stocks (variety and rootstock) and its outputs (wort and wine). Initially, it was characterized and delineated vegetation, climate, lithology and geomorphology (landforms, drainage, altitude, exposition and slope) and soils as environmental agents, which shape the terroir of Campo de Borja?s Appellation (Gómez-Miguel et al., 2014; Lázaro-López et al., 2015). On this work, we are aimed to describe process of outlining and defining of HTU and terroir. As a result, HTU with the best score of the Appellation are highlighted as the outcome of the concoction between zoning of every single factor and the wine quality assessment (Quality index, QI). On balance, it has been detailed 22 terroir [(J02, J03, J04, J05, J06, J07, J08, J09, J10, J11, J13, J14, J16, J17, J18, J19, J20) and ( CxPT1G, CxpT2T, CxpT3T, HxaC3y5, PxAC1T)] distributed on 17 HTU (03C, 04C, 05C, 07C, 08C, 09C, 10C, 11C, 12C, 13C, 15C, 16C, 18C, 19C, 21C, 23C, 29C). The concluding map pictures a land assessment related to the wine quality, shorting them into different categories of relative quality. Altogether illustrates the vineyard?s scene of the region and its potency of development. In fact, the best HTUs collect three quarters of the vineyards, when they only gather one third of the whole area, which heads to an outlook of growth of 15,599.27 ha. Regarding the suitable HTUs too, this area could reach up to 24,845.1 ha, assembling 13% of Appellation?s vineyard. As far as grapevine variety is concerned, Grenache, Tempranillo, Syrah, Cabernet Sauvignon share a same growing rate. | |
