The role of the environmental factor as a component of the terroir in Spain (A.O. Cigales, NW Spain)

Abstract

The components and the methodology for characterization of the terroir in Spain have been described by Gómez-Miguel et al. (2003) and 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 specific variables of the country’s viticulture (i.e: size and distribution of vineyards, varieties, phenology, productivity, quality, designation regulations, etc.). This paper describes: the integration of the resulting database in a Geographic Information System (GIS) 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 over 2.4 million ha. This paper presents the results of a case studied in the Cigales region (A.O. Cigales) that expands on 62,210.5 ha and includes 2,351.5 ha of vineyards. The observed distribution of vineyards in this region is ¿well? 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 59 percent of the total area sustains over 95 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: 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 (UHM) (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).

The role of mechanization in zone/terroir expression

Vineyard mechanization will be addressed in this review paper primarily as related to pruning and harvesting since these operations typically require a great deal of the total yearly labour demand (Intrieri and Poni, 1998). However, to be able to define how mechanization interacts with “terroir”, a rigorous definition of the latter term is needed.

White wine light-strike fault: a comparison between flint and green bottles under the typical supermarket conditions

Consumer preference favors flint-glass wine bottles over the traditional dark-colored, but it is documented that light exposure can cause white wines to produce off-aromas and change in color, and consequently da[1]mage their quality. Aim of the study was to study the white wine shelf life under the typical supermarket conditions, by recording the light and temperature exposure, the colorimetric changes, and the light-strike fault. METHODS: One pilot experiment based on two white wines and eight-time points and one kinetic experiment based on four white wines and seven-time points were designed and realized using a typical supermarket shelf for 32 and 50 days, correspondently. By installing prototype sensors at 32 points of the shelf, the temperature, UV, IR, and Visible light exposure were registered every 10 min. Approximately 600 commercial wines, bottled in flint and colored glass, were used. The colorimetric changes of the wines were registered and the light-strike fault was evaluated.

Genetic and hormonal regulation of grape berry cuticle formation

The plant surface typically comprises of various epidermal cell types which synthesise and deposit a protective waxy layer known as the cuticle. The cuticle is a significant contributor to important crop traits related to drought tolerance, biotic stress, postharvest fruit quality as well as providing structural support. In this work we have investigated grape berry cuticle formation in the context of the accumulation of anti-fungal specialised metabolites and the ability of the cuticle to structurally cope with the rapid expansion of ripening berries. Metabolic QTL analysis was performed in a grapevine cross population, using chemical profiling data collected via GC-MS analysis for cuticular waxes.

Caractérisation du terroir en Espagne : méthodologie de l’évaluation et de la validation

In recent years, there has been a growing interest in characterizing the ecological environment of vineyard production, and the growing need to delimit and characterize with precision the different homogeneous viticultural units. This has allowed the development of new studies which have as their objective the Vineyard Zoning. The delimitation and characterization of wine-growing areas poses specific problems in Spain, not only linked to the specific characteristics of the territory, but also to the size, distribution and index of viticultural occupation in the designations of origin.

Varieties and rootstocks: an important mean for adaptation to terroir

A large genetic diversity exists among V. vinifera varieties, but also among cultivated rootstocks. This diversity is important to adapt plant material to different environmental conditions
