Terroir studies in the Eger wine region of Hungary
Abstract
The aim of our study was to use an advanced methodology to create a geo-referenced model database describing production sites in the Eger wine region of Hungary. The database includes geo-referenced information of geomorphology (slope, exposition, and elevation), lithology, soil type, depth of water table and pH of soil water. Special dataset of 3 production sites cultivating Vitis vinifera L. cv. ‘Kékfrankos’ (Blaufränkisch), the most abundant red grape variety of the Eger wine region and of Hungary was introduced in the database. The vines on the selected sites were of similar age, as well as of plant and row distance; all vertically shoot positioned. Soil and canopy management were performed similarly.
Meteorological data were collected from automatic weather stations nearby the examined sites, physical and chemical soil properties were analyzed, phenological stages, yield quantity and quality, as well as wine analytical data and the results of organoleptic evaluation were registered for 3 years. Ortophotos of the investigated sites and hyperspectral NDVI pictures of the sites were also added to the database. This study serves as the first model for Hungary, how GIS can aid the classification and characterization of different terroirs and may promote the elaboration of a precise viti-vinicultural practice and appellation origin control system.
