The role of the landscape as a component of the terroir in Spain (DO Somontano, NE Spain)

Abstract

The components and methodology for characterization of the terroir in Spain have been described by Gómez-Miguel et al. (2003), Sotés et al. (2003), taking into account the full range of environmental factors (i.e: climate, vegetation, topography, soils, altitude, etc.), landscape variables (derived from photo-interpretation and a digital elevation model), and variables specific to the country’s viticulture (i.e: size and distribution of the vineyards, varieties, phenology, productivity, quality, designation regulations, etc.). This paper describes the integration of the resulting database in a Geographic Information System (G.I.S.) that allows the spatial and statistical analysis of all variables; the parametric system of variable quantification; the selection of main endogenous and exogenous variables for terroir characterization; and the role of the variables that describe the landscape in the final results. The analysis has been carried out on over 1.8 million ha. This paper presents the results of a case study in the county “Somontano” that covers an expanse of 142,000 ha and includes 4,173 ha of vineyards. The observed distribution of vineyards in this county is correlated to the integrated landscape-terrain classification and productivity but does not depend on the total available area for cultivation. It is significant that a subset of geological formations that accounts for 45 percent of the total area sustains over 90 percent of the vineyards.
The results of the study have general implications for landscape-terrain classification in Spain and define a set of methodological guidelines. These guidelines refer to:
a) Definition of the set of variables that define the landscape: characterization of the lithological and morphological components; homogenization of lithological units; cartography of the geological formations; integration of a digital elevation model to derive altitude, orientation, exposure, and slope. The spatial scale should be at least 1:25.000.
b) Definition of the Homogeneous Land Units (HLU): The parameter characterization was carried out from the units which were previously defined from the data of the environmental analysis.
c) Experimental design: Selection of Homogeneous Land Units and characterization within the units.
d) Final zoning: Integration of the Homogeneous Land Unit with the plant (variety and rootstock) and the product (must and wine).

Effects of abscisic acid treatment on Vitis vinifera L. Savvatiano and Mouchtaro grapes and wine characteristics

Grapes development is determined by grape cultivar and vineyard climatic conditions and consequently affecting the phenolic and aroma on grapes and wines. Abscisic Acid (ABA) plays a key role in the promotion of fruit ripening and fruit anthocyanin content. Herein, we report the impact of ABA to grape ripening and wine quality.

Pinot noir: an endemic or a flexible variety?

Pinot noir has its historical roots in Burgundy and is generally considered as an endemic vine variety which means that its adaptation is very specific to this environment

Predatory Arthropods associated with potential locally-adapted native insectary plants for Australian vineyards

Three locally-adapted native plants were evaluated to determine their capacity to provide insectary benefits to predatory arthropods in association with vineyards, and thereby to enhance biological control of insect pests. Native plants are preferred as supplementary flora, as they are naturally adapted to Australia’s climatic conditions.

Influence de l’ensoleillement sur la composante aromatique des baies de raisin

Syrah is a grape with weak aromatic expression. This atypical grape variety as a fruit allows the production of wines of great reputation for which the aromatic particularity plays an important role. The varietal aroma consists of volatile substances directly perceptible by the olfactory mucosa and of aroma precursors, of which the glycosides constitute an important class.

Investigating the role of endophytes in enhancing grapevine resilience to drought

Grapevine is a crop of great economic importance for several countries. The intensification of grapevine production has mostly been sustained by the increasing use of water resources at the expense of the environmental water balance. Moreover, in the last decades, climate change and the consequent expansion of drought have further compromised water availability, making current agricultural systems even more fragile both ecologically and economically. Recently, many research groups have highlighted the important role of endophytes in facilitating plant growth under optimal or stressful conditions. Within the framework of the PRIMA project, we aim to investigate the possible exploitation of the natural endophyte biodiversity as a sustainable tool to make grapevine plants more resilient to water deficit environmental conditions.
